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
General Motors has decided that certain 2019-2020 model year Chevrolet Medium Duty 4500HD/5500HD/6500HD vehicles fail to conform to S5.3.1(c) of Federal Motor Vehicle Safety Standard (FMVSS) No. 105, “Hydraulic and Electric Brake Systems.” If the vehicle’s body control module (BCM) loses communication with the vehicle’s electronic brake control module (EBCM), the vehicle’s antilock brake system (ABS) malfunction indicator lamp (MIL) will not illuminate as required by FMVSS 105. The vehicle’s service-engine-soon MIL will illuminate. If an owner is unaware that the ABS system is not functioning properly, the owner may not have it serviced, increasing the risk of a crash.
Correction
Dealers will update the software calibration for the body control module (BCM).
Parts
There are no parts required for this repair.

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.

• 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

pack disconnected from the AC voltage supply. DO NOT connect a battery charger.
• Turn OFF or disable systems that may put a load on the vehicles battery such as; interior lights, exterior lights
(including daytime running lights), HVAC, etc.
• Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M)
system status indicators to NO.

Dealer Responsibility – For USA
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 under a sale or lease until the defect or noncompliance is
remedied.
The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type
must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair
within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the
condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably
equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To
avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment
with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told
how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable
time.
Dealer Responsibility – All
All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers’ possession
and subject to this recall must be held and inspected/repaired per the service procedure of this bulletin before customers
take possession of these vehicles. Involved vehicles must be held and not delivered to customers, dealer-traded,
released to auction, used for demonstration, or any other purpose.
All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System
(CPOIS) will be de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting
FMVSS Noncompliance Recall

Only
Page 4 of 4
an accepted/paid warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified
for sale within the CPOIS system, or once again be used in the CTP program.
Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle,
or ownership, from this time forward.
Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer
information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the
required correction according to the instructions contained in this bulletin. Recall follow-up cards should not be used for
this purpose, since the customer may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this field action enters your vehicle inventory you must take the steps
necessary to ensure the program correction has been made before selling the vehicle. In addition, for vehicles entering
your facility for service, you are required to ensure the customer is aware of the open field action and make every
reasonable effort to implement the program correction as set forth in this bulletin prior to releasing the vehicle.
Dealer Reports
For dealers with involved vehicles, a listing with involved vehicles has been prepared and will be provided to U.S. and
Canadian dealers through the GM GlobalConnect Recall Reports or sent directly to export dealers. The listing may
contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor
vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in
several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to
complete this recall.
Customer Notification
USA – General Motors will notify customers of this recall on their vehicle.
Customer Reimbursement
Customer requests for reimbursement of previously paid repairs to correct the condition described in this bulletin are to
be submitted to the dealer prior to or by June 30, 2021. See General Motors Service Policies and Procedures Manual,
Product Field Action Customer Reimbursement Procedure (USA) or local Policies and Procedures, for details.
GM bulletins are intended for use by professional technicians, NOT a “do-it-yourselfer”. They are written to inform these technicians of
conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained
technicians have the tools, equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT
assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your dealer for information on whether your
vehicle may benefit from the information.
