2023 2023 RPO EM2 ML5 PCJ Description
200” Wheel Base
212” Wheel Base ADAS System Involved vehicles are marked “Open” on the Investigate Vehicle History screen in GM Global Warranty Management system. This site should always be checked to confirm vehicle involvement prior to beginning any required inspections and/or repairs.
Condition Isuzu Motors Limited has decided that a defect, which relates to motor vehicle safety, exists in certain 2023 model year Chevrolet Low Cab Forward 5500HD/XD Medium Duty vehicles with 200 inch or 212 inch wheelbase. For these vehicles, the ADAS (Advanced Driver Assistance Systems) camera and ABS (Antilock Brake System) module were not calibrated according to the correct wheelbase.
Therefore, when driving in a curve certain ADAS features and the ESC (Electronic Stability Control) system working together with the ABS module may not function properly. If the ADAS camera and ABS module are not calibrated to the correct wheelbase option, one or more of the following events could occur – in each case, increasing the risk of a crash:
• Automatic Emergency Braking System (AEBS) activation (as well as the AEBS warning light) may be delayed when driving in a curve and therefore the AEBS may then decelerate the vehicle more aggressively when activated.
• Adaptive Cruise Control may reduce following distance by about 8-10 m when driving in a curve.
• ESC may activate in an understeer condition without illuminating brake lights.
• ESC may delay activation in an oversteer condition, increasing potential for an oversteer event to occur.
Correction Dealers will recalibrate (1) the ADAS camera to the correct wheelbase of the vehicles, and (2) the ABS module so the ESC system will function properly with the affected vehicles’ wheelbases.

2. Select and start SPS2.
3. Select Settings (1).
4. Select the Warranty Claim Code tab (2).
The VIN, Warranty Claim Code and Date/Time will be listed on a roster of recent programming events. If the code is retrievable, dealers should resubmit the transaction making sure to include the code in the SPS Warranty Claim Code field.
Note: Carefully read and follow the instructions below.
• Ensure the programming tool is equipped with the latest software and is securely connected to the data link connector. If there is an interruption during programming, programming failure or control module damage may occur.
• Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. Install a GM Authorized Programming Support Tool to maintain system voltage. Refer to www.gmdesolutions.com for further information. If not available, connect a fully charged 12 V jumper or booster pack disconnected from the AC voltage supply. DO NOT connect a battery charger.
• Follow the on-screen prompts regarding ignition power mode, but ensure that anything that drains excessive power (exterior lights, HVAC blower motor, etc) is off.
• Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO.
Important: The service technician always needs to verify that the VIN displayed in the TLC left side drop down menu and the top center window match the VIN plate of the vehicle to be programmed prior to using Service Programming System 2 (SPS2) for programming or reprogramming a module.
• For the TLC application, service technicians need to always ensure that the power mode (ignition) is “ON” before reading the VIN from the vehicle’s VIN master module and that they do not select a VIN that is already in the TLC application memory from a previous vehicle.
• If the VIN that shows up in the TLC top center window after correctly reading the VIN from the vehicle does not match the VIN plate of the vehicle, manually type in the VIN characters from the vehicle VIN plate into the TLC top center window and use these for programming or reprogramming the subject module with the correct vehicle VIN and software and/or calibrations.
• The Engine Control Module (ECM) is the master module (for VIP vehicles) that TLC reads to determine the VIN of the vehicle. If the VIN read from the vehicle by TLC does not match the VIN plate of the vehicle, the ECM also needs to be reprogrammed with the correct VIN, software and calibrations that match the vehicle’s VIN plate.
• The Body Control Module (BCM) is the master module (for GEM vehicles) that TLC reads to determine the VIN of the vehicle. If the VIN read from the vehicle by TLC does not match the VIN plate of the vehicle, the BCM also needs to be reprogrammed with the correct VIN, software and calibrations that match the vehicle’s VIN plate.
Caution: Be sure the VIN selected in the drop-down menu (1) is the same as the vehicle connected (2) before beginning programming. Page 3 of 25 Product Safety Recall

Important: If the vehicle VIN DOES NOT match, the message below will be shown. 5877000 Important: Techline Connect screens shown above. 5644477 Important: If the same calibration/software warning is noted on the TLC Summary screen, select OK and follow screen instructions. After a successful programming event, the WCC is located in the Service Programming System dialogue box of the SPS Summary screen. No further action is required. Refer to the Warranty section of the bulletin.
The following procedure was intended to be performed indoors. If your circumstances do not allow you to program the Front view Camera Programming indoors, an alternative, outdoor procedure is available. However, this indoor procedure is preferable.
This procedure will instruct you how to program the Front view Camera by establishing the centerline of the vehicle, determining the amount of offset of the Front view Camera, properly positioning the Front view Camera Target parallel to the front of the vehicle, and completing the procedure by entering three measurements taken during the procedure into IDSS. Page 4 of 25 Product Safety Recall
N232396501 ABS Module and Frontview Camera Module Reprogramming Carefully read the following procedure before performing it. Then, perform all the steps in order and exactly as written.
Important:
• The scan tool used for this procedure must be the same from start to finish. If the scan tool is changed midway, the procedure will fail.
• Do NOT touch the camera lenses.
• The vehicle should be unloaded (no cargo) and no one should be in the vehicle while performing this procedure. Use IDSS from outside the driver’s door.
• Use masking tape on the floor to mark on to avoid permanently marking the floor.
• Be sure the tires installed on the vehicle are all the same size and meet the original manufactured specification. Tire sizes other than the OEM specification may cause the ADAS system to not function properly. Do not program the Front view Camera until the correct tires are installed on the vehicle.
• Due to the time requirements of programming, it is recommended that an external power source be used to maintain system voltage. Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming.
To ensure trouble-free programming, it is recommended to use one of the following external power sources:
• A Midtronic PCS charger
• A fully charged 12V jumper or booster pack disconnected from the AC voltage supply Special Tools and Supplies
• J-53207 Laser Measuring Tool
• J-53325 Cross-line Laser Level
• GE-53292 Plumb Bob/ Twisted Link Set (2 included)
• GE-53206 Stereo Camera Target
• GE-53291 Target Stand

Condition
Isuzu Motors Limited has decided that a defect, which relates to motor vehicle safety, exists in certain 2022-2023 model year Chevrolet Low Cab Forward 5500HD/XD Medium Duty vehicles with 200 inch or 212 inch wheelbase. For these vehicles, the ADAS (Advanced Driver Assistance Systems) camera and ABS (Antilock Brake System) module were not calibrated according to the correct wheelbase. Therefore, when driving in a curve certain ADAS features and the ESC (Electronic Stability Control) system working together with the ABS module may not function properly. If the ADAS camera and ABS module are not calibrated to the correct wheelbase option, one or more of the following events could occur – in each case, increasing the risk of a crash:
• Automatic Emergency Braking System (AEBS) activation (as well as the AEBS warning light) may be delayed when driving in a curve and therefore the AEBS may then decelerate the vehicle more aggressively when activated.
• Adaptive Cruise Control may reduce following distance by about 8-10 m when driving in a curve.
• ESC may activate in an understeer condition without illuminating brake lights.
• ESC may delay activation in an oversteer condition, increasing potential for an oversteer event to occur.
Correction
Dealers will recalibrate the ABS module so the ESC system will function properly with the affected vehicles’ wheelbases.
Parts
No parts are required for this repair.

• Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. Install a GM Authorized Programming Support Tool to maintain system voltage. Refer to www.gmdesolutions.com for further information. If not available, connect a fully charged 12 V jumper or booster pack disconnected from the AC voltage supply. DO NOT connect a battery charger.
• Follow the on-screen prompts regarding ignition power mode, but ensure that anything that drains excessive power (exterior lights, HVAC blower motor, etc) is off.
• Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO.
Important: The service technician always needs to verify that the VIN displayed in the TLC left side drop down menu and the top center window match the VIN plate of the vehicle to be programmed prior to using Service Programming System 2 (SPS2) for programming or reprogramming a module.
• For the TLC application, service technicians need to always ensure that the power mode (ignition) is “ON” before reading the VIN from the vehicle’s VIN master module and that they do not select a VIN that is already in the TLC application memory from a previous vehicle.
• If the VIN that shows up in the TLC top center window after correctly reading the VIN from the vehicle does not match the VIN plate of the vehicle, manually type in the VIN characters from the vehicle VIN plate into the TLC top center window and use these for programming or reprogramming the subject module with the correct vehicle VIN and software and/or calibrations.
• The Engine Control Module (ECM) is the master module (for VIP vehicles) that TLC reads to determine the VIN of the vehicle. If the VIN read from the vehicle by TLC does not match the VIN plate of the vehicle, the ECM also needs to be reprogrammed with the correct VIN, software and calibrations that match the vehicle’s VIN plate.
• The Body Control Module (BCM) is the master module (for GEM vehicles) that TLC reads to determine the VIN of the vehicle. If the VIN read from the vehicle by TLC does not match the VIN plate of the vehicle, the BCM also needs to be reprogrammed with the correct VIN, software and calibrations that match the vehicle’s VIN plate.
Caution: Be sure the VIN selected in the drop-down menu (1) is the same as the vehicle connected (2) before beginning programming.

Repair Instructions
Stereo Camera Programming
The following procedure was intended to be performed indoors. If your circumstances do not allow you to program the Stereo Camera Programming indoors,
an alternative, outdoor procedure is available. However, this indoor procedure is preferable.
This procedure will instruct you how to program the ADAS Stereo Camera by establishing the centerline of the vehicle, determining the amount of offset of the
Stereo Camera, properly positioning the Stereo Camera Target parallel to the front of the vehicle, and completing the procedure by entering three
measurements taken during the procedure into IDSS.
Carefully read the following procedure before performing it. Then, perform all the steps in order and exactly as written.
Important:
• The scan tool used for this procedure must be the same from start to finish. If the scan tool is changed midway, the procedure
will fail.
• Do NOT touch the camera lenses.
• The vehicle should be unloaded (no cargo) and no one should be in the vehicle while performing this procedure. Use IDSS from
outside the driver’s door.
• Use masking tape on the floor to mark on to avoid permanently marking the floor.
• Be sure the tires installed on the vehicle are all the same size and meet the original manufactured specification. Tire sizes other
than the OEM specification may cause the ADAS system to not function properly. Do not program the ADAS Stereo Camera until the correct tires
are installed on the vehicle.
• Due to the time requirements of programming, it is recommended that an external power source be used to maintain system
voltage. Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming.
To ensure trouble-free programming, it is recommended to use one of the following external power sources:
o A Midtronic PCS charger
o A fully charged 12V jumper or booster pack disconnected from the AC voltage supply
Special Tools and Supplies
• J-53207 Laser Measuring Tool
• J-53325 Cross-line Laser Level
• GE-53292 Plumb Bob/ Twisted Link Set (2 included)
• GE-53206 Stereo Camera Target
• GE-53291 Target Stand
NOTE: All measurements taken and input in this procedure MUST be in metric units (e.g., millimeters).
1. Ensure the Vehicle is not loaded. Position the vehicle on a flat, even, hard, and level surface. Ensure that there is at least 8.0 Meters (26.5
feet) of flat, even, hard, and level surface directly in front of the vehicle. This area must be clear of all objects (shop equipment, poles, other
vehicles, etc.) at least 2 meters (6.5 feet) from each side of the centerline of the front of the vehicle. (See Figure 1.) Ensure the parking brake
is set.
2. Ensure that the windshield is clean, and the wheels are straight ahead.
3. Ensure that the tire size is correct for the vehicle and the tire pressure on all tires has been adjusted to proper specifications.

12. When completed there should be 2 Xs under the vehicle as shown labeled A and B in Figure 10.
13. Remove both Plumb Bobs from the frame holes.
PLUMB BOB STRING SET UP
14. If not already completed per the special tool instructions, make two overhand loops in one of the Plumb Bob strings as shown in Figure
11. The overall length from loop to loop when stretched taut should be approximately 54cm.
KBTree Page 6 of 21
about:blank 1/19/2023
ESTABLISHING CENTERLINE OF VEHICLE
Important: when performing Steps 15 – 20, it is critical that the looped string be held taut. Also, the exact position of the loops on the marker pen
and the Plumb Bob point must be kept the same for each Step. Finally, both the Plumb Bob point and the marker pen should be kept completely
straight up while performing each Step.
NOTE: When performing Steps 15 – 20, refer to Figure 12.
15. Using the Plumb Bob weight point, hold one of the loops steadily on Point (A) made on the passenger’s side of the vehicle. Place the
capped marker pen into the other loop and put the string taut. Pull the taut string towards to the rear-center of the vehicle to make an
estimation of where the masking tape should be for marking the floor and put down a piece of masking tape. (See Figure 12.)
16. Perform Step 15 again, but with the marker pen uncapped, to create about a 3-inch arc on the masking tape at Point (C). (See Figure
13.)
KBTree Page 7 of 21
about:blank 1/19/2023
17. Perform Steps 15 and 16 towards the front-center of the vehicle to create a marked arc on the floor at Point (D). (See Figure 12.)
18. Place the point of the Plumb Bob weight into one loop with the point lightly pressed down directly on the center of Point (B) made on the
driver’s side of the vehicle. Place the capped marker pen into the other loop and pull the string taut. Pull the taut string towards to the rearcenter
of the vehicle to determine if more masking tape is needed on the floor. Lay down more masking tape as necessary. (See Figure 12.)
19. Perform Step 18 again, but with the marker pen uncapped, to create about crossed arc at Point (C) on the floor. (See Figure 12.)
20. Perform Steps 18 and 19 towards the front-center of the vehicle to create a crossed arc at Point (D) on the floor. (See Figure 12.)
21. From about three feet in front of the vehicle use the Cross-Line Laser Level (Special Tool J-53325) to establish the centerline of the
vehicle by placing the tool on the floor, turning it on, and aiming the beam directly through the intersection of both points C and D. (See
Figure 14.)
NOTE: Ensure that enough room is left from the front of the bumper to the Cross-Line Laser Level to allow for about a 12-inch strip of masking tape
laid on the floor lengthwise with the vehicle.
NOTE: When performing Steps 21 – 22, refer to Figure 14.
22. With the Cross-Line Laser Level still in place, put down a 12-inch piece of masking tape lengthwise under the laser beam directly in front
KBTree Page 8 of 21
about:blank 1/19/2023
of the Cross-Line Laser Level. Trace the laser beam line onto the piece of masking tape with a marker pen. (See Figure 14.) This is the
Center of the Vehicle reference mark.
Establish Camera Offset
NOTE: For Steps 23 – 29, refer to Figure 15 as a reference.
23. With the Cross-Line Laser Level still in place, lay an approximately 16” strip of masking tape horizontally on the windshield about 4 inches
above the stereo camera. (See Figure 16.)
24. Use a piece of cardboard angled above the masking tape to reflect the laser beam as shown in Figure 17. Use the laser light to mark the
center of the vehicle on the masking tape with two dots above each other. Use a ruler to connect the dots into a straight line with a ball point
pen. (See Figure 18.) Label this line as the centerline of the truck (C.T.).
KBTree Page 9 of 21
about:blank 1/19/2023
25. Use the mount for the Cross-Line Laser Level to attach it to the end of the Target Stand (Special Tool GE-53291) as shown in Figures 19
and 20. Which way the laser will have to be mounted depends on how high the Stereo Camera is mounted on the vehicle you are servicing.
NOTE: Adjust the Cross-Line Laser Level height as close as possible to the center of the left (passenger) Stereo Camera lens. If the laser beams
flash at any point during Steps 26 and 27, the Cross-Line Laser Level MUST be adjusted so that the angle and height of the horizontal laser beam is
more level with the Stereo Camera lens.
26. Point the Cross-Line Laser Level at the passenger side Stereo Camera lens and adjust the Laser until the passenger side lens is
bisected vertically and horizontally. (See Figure 21.)
KBTree Page 10 of 21
about:blank 1/19/2023
27. Trace the vertical laser beam over the center of the passenger side lens onto the strip of masking tape over the camera with a ball point
pen. (See Figure 15.) Mark this line as the center of the lens (C.L.).
28. Keeping the ruler or tape measure parallel with the floor, measure 80mm towards the driver’s side from the center of the lens line and
make a dot with a ball point pen. This is the center of the camera. (See Figure 15.) Mark the dot center of camera (C.C.).
29. Measure the distance between the center of the truck (C.T.) and the center of the camera (C.C.) in millimeters and write it down for later
use. This measurement is the camera offset of the vehicle.
Establish Camera Height
30. Ensure that the Cross-Line Laser Level is still bisecting the passenger side Stereo Camera Lens as shown in Figure 21. Adjust the laser
as necessary.
31. Place the end of a tape measure on the floor. Extend the tape measure straight upwards. Record where the horizontal laser beam
crosses the tape measure (See Figure 22) and write it down for later use. This is the height of the camera.
KBTree Page 11 of 21
about:blank 1/19/2023
Set Up Target
32. Remove the Cross-Line Laser Level from the Target Stand and the mount. Place the Cross-Line Laser Level on the floor and turn it on
facing forward from the front of the vehicle. Align the laser beam with the Vehicle Centerline reference mark made on the floor in Step 22.
(See Figure 23.)
33. If not already completed per the special tool instructions, attach the Stereo Camera Target (Special Tool GE-53206) to the Target Stand
(Special Tool GE-53291). Refer to Figure 24 and adjust the height of the target so that both ends of the target position line are 1,000mm
(1m) above the floor.
KBTree Page 12 of 21
about:blank 1/19/2023
34. Tape the Plumb Bob string without the loops to the top of the Target Stand. The Plumb Bob string must pass directly through the center
of the Target (over the small center mark) as shown in Figure 25. The Plumb Bob weight point should barely be off the floor.
Establishing Target Distance for 4650mm (+/- 20mm)
NOTE: Adjusting the Target distance should be done by two people.
KBTree Page 13 of 21
about:blank 1/19/2023
35. Turn on the Laser Measuring Tool (Special Tool J-53207) and place it against the center of the vehicle’s front bumper cover facing
forward. (See Figure 26.)
36. Using the Laser Measuring Tool, place the center of the Target 4,650 mm (+/- 20 mm) from the center of the front bumper cover. (See
Figure 27.)
37. Adjust the Target until the Cross-Line Laser Level beam is directly over the Plumb Bob string and the small center mark shown in Figure
25.
38. Ensure that the middle of the target is still 4,650 mm (+/- 20 mm) from the vehicle’s front bumper cover. Adjust the target as necessary.
Apply about a 2-foot length of masking tape to the floor centered under the Plumb Bob point, running lengthwise with the laser beam. Mark
the masking tape with an X directly underneath the point of the Plumb Bob weight. (See Figure 28.)
KBTree Page 14 of 21
about:blank 1/19/2023
39. Use a ruler or piece of cardboard tilted an angle to see the laser beam on the masking tape. (See Figure 29.) Establish two different
points of the laser beam about 1 foot apart on the lengthwise masking tape with a dot from the marker pen. (See Figure 30.) Connect the two
dots with a straight edge and mark a line. (See Figure 31.)
Establishing Target Distance for 7650mm (+/- 20mm)
NOTE: Adjusting the Target distance should be done by two people.

IMPORTANT SAFETY RECALL
March 2023
This notice applies to your vehicle, VIN: _____________________________________
Dear General Motors Customer:
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.
Isuzu Motors Limited has decided that a defect, which relates to motor vehicle safety, exists in certain 2022-2023 model year Chevrolet Low Cab Forward 5500HD/XD Medium Duty vehicles with 200 inch or 212 inch wheelbase. These vehicles are manufactured by Isuzu. As a result, GM is conducting a safety recall.
IMPORTANT
• Your vehicle is involved in GM recall N232396500.
• Schedule an appointment with your GM dealer.
• This service will be performed for you at no charge.
Why is your vehicle being recalled?
The Antilock Brake System (ABS) module was not calibrated according to the correct wheelbase. Therefore, when driving in a curve the Electronic Stability Control (ESC) system, working together with the ABS, may react prematurely or be delayed in reacting, therefore increasing the risk of a crash.
What will we do?
Your Chevrolet dealer will recalibrate the ABS module so the ESC system will function properly with the affected vehicles’ wheelbases. This service will be performed for you at no charge. Because of service scheduling requirements, it is likely that your dealer will need your vehicle longer than the service correction time of approximately 40 minutes.
What should you do?
You should contact your Chevrolet dealer to arrange a service appointment as soon as possible.
When scheduling your appointment, confirm with the dealer that they service Medium Duty Trucks.
Do you have questions?
If you have any questions or concerns that your dealer is unable to resolve, please contact the appropriate Customer Assistance Center at the number listed below.
For the hearing or speech impaired, please contact our Customer Assistance Center using the Telecommunication Relay Service by dialing 711 then providing the appropriate Customer Assistance Center number for your vehicle.

To: All General Motors Medium Duty Dealers
STOP DELIVERY ORDER
Effective immediately, stop the delivery of certain 2022-2023 model year Chevrolet Low Cab Forward 5500HD/XD Medium Duty vehicles in new or used vehicle inventory. Isuzu Motors Limited, the manufacturer of these vehicles, has notified the National Highway Traffic Safety Administration (NHTSA) about an upcoming safety recall that involves these vehicles. The GM recall number is N232396500.
It is a violation of federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification until the defect is remedied.
Isuzu Motors Limited has decided that a defect, which relates to motor vehicle safety, exists in certain 2022-2023 model year Chevrolet Low Cab Forward 5500HD/XD Medium Duty vehicles with 200 inch or 212 inch wheelbase. For these vehicles, the ADAS (Advanced Driver Assistance Systems) camera and ABS (Antilock Brake System) module were not calibrated according to the correct wheelbase. Therefore, when driving in a curve certain ADAS features and the ESC (Electronic Stability Control) system working together with the ABS module may not function properly. If the ADAS camera and ABS module are not calibrated to the correct wheelbase option, one or more of the following events could occur – in each case, increasing the risk of a crash:
• Automatic Emergency Braking System (AEBS) activation (as well as the AEBS warning light) may be delayed when driving in a curve and therefore the AEBS may then decelerate the vehicle more aggressively when activated.
• Adaptive Cruise Control may reduce following distance by about 8-10 m when driving in a curve.
• ESC may activate in an understeer condition without illuminating brake lights.
• ESC may delay activation in an oversteer condition, increasing potential for an oversteer event to occur.
Dealers will recalibrate (1) the ADAS camera to the correct wheelbase of the vehicles, and (2) the ABS module so the ESC system will function properly with the affected vehicles’ wheelbases.
Until further instructions are received, involved vehicles that are in dealers’ possession (new or used vehicle inventory, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc.) must be held and not delivered to customers, dealer-traded, released to auction, used for demonstration purposes or any other dealer use. All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System (CPOIS) will be de-certified.
The Investigate Vehicle History (IVH) screen in the Global Warranty Management (GWM) system has been updated for this upcoming recall. This action has been taken to assist dealers with determining which vehicles are involved so they can properly respond to customer inquiries.
A list of involved vehicles that have been identified as being in dealer new vehicle inventory is attached to this message. It is sorted by dealer Business Associate Code (BAC) for easy reference. Your dealership’s BAC will not be listed if none of the involved vehicles are currently in your new vehicle inventory. To identify involved vehicles in dealer used inventory, run an Open VIN Report or Field Action Initiation Report using Field Action Reports-GFAM within the Maxis Dealer Application in GlobalConnect.
Question and Answer Document (Q&A)
Attached to this message you will find a document that addresses the ten most likely questions customers may have regarding this Safety Recall. Please use this information as an aid to confidently answer customer concerns.
Until the recall bulletin is released, the Investigate Vehicle History (IVH) screen in the Global Warranty Management (GWM) system will display “01/23/2023” under Release Date and “Incomplete – Remedy Not Available” under Status. This means the required repair is not yet available and dealers should not attempt to perform any repairs.
We are working with the supplier to obtain the required parts as quickly as possible. When a sufficient quantity of parts is available, the recall bulletin will be released, and dealers can begin repairing vehicles.

Description of the Defect : When the subject vehicles were modified to extend the frame to a 200 inch or 212 inch wheelbase, the ADAS camera and ABS module were not recalibrated to account for the different inputs from the vehicle resulting from the stretched frame. Therefore, when driving in a curve certain ADAS features and the ESC system working together with the ABS module may not function properly.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : If the ADAS camera and ABS module are not recalibrated after the frame is
stretched, one or more of the following events could occur – in each case, increasing the risk of a crash:
• Automatic Emergency Braking System (AEBS) activation (as well as the AEBS warning light) may be delayed when driving in a curve and therefore the AEBS may then decelerate the vehicle more aggressively when activated.
• Adaptive Cruise Control may reduce following distance by about 8-10 m when driving in a curve.
• ESC may activate in an understeer condition without illuminating brake lights.
• ESC may delay activation in an oversteer condition, increasing potential for an oversteer event to occur.
Description of the Cause : The ADAS camera and ABS module were not recalibrated after the frame was stretched. Identification of Any Warning NR
that can Occur : Involved Components : Component Name 1 : Electronic Hydraulic Control Unit (EHCU)
Component Description : Base component for controlling the hydraulic service brakes. Anti-lock Brake System, Electronic Stability Control, Automatic Emergency Braking.

Description of Remedy :
Description of Remedy Program : Isuzu dealers will recalibrate (1) the ADAS camera to account for the
(extended) length of the vehicles, and (2) the ABS module so the ESC system will function properly with the affected vehicles’ longer wheelbases. All subject vehicles are covered under the New Truck Warranty. There is no expectation that these vehicles will need to be remedied outside of the warranty period. How Remedy Component Differs from Recalled Component :
Identify How/When Recall Condition was Corrected in Production : Physically there is no difference, this is a recalibration of the ABS module and ADAS camera.
On January 10, 2023, INAC QA travelled to the frame modification facilities that carry out the “factory option” frame extensions on behalf of Isuzu and trained the staff so all modified trucks produced after 1/10/2023 have the ADAS cameras and ESC systems properly calibrated. Recall Schedule :
Description of Recall Schedule : Isuzu, Chevrolet, and Hino will notify their respective vehicle owners and
dealers of this recall. Customers will be informed that the recall repairs will be done free of charge. The recall owner notification is expected to begin 3/10/2023. For additional information, Isuzu owners may contact Isuzu Customer Relations at 1-866-441-9638, Chevrolet owners may contact the GM Medium Duty Truck assistance line at 1-800-862-4389, and Hino owners may contact Hino Customer Service at 1-248-699-9390.
