Copyright 2022 General Motors LLC. All Rights Reserved. Service Bulletin Bulletin No.: 22-NA-007 Date: October, 2022 TECHNICAL Subject: Poor Engine Performance in Extremely Cold Weather Conditions for LE2 Engines, Charge Air Cooler (CAC) Icing – Malfunction Indicator Lamp (MIL) Illuminated, DTC P0299, P0234, P0236, P2227, P00C7 Set Brand: Model: Model Year: VIN: Engine: Transmission: from to from to Chevrolet Cruze 2016 2019 — — 1.4L Turbo (LE2) — Involved Region or Country North America Condition Some customers may comment that when driving short distances and/or slow speed driving cycles, their vehicle experiences one or several of the following conditions within the first 10 to 15 minutes of vehicle operation in extremely cold weather conditions (-18°C or less / 0°F or less): • Loss of power • Hesitation on acceleration • Stalling condition • May also notice a Malfunction Indicator Lamp illuminated • After driving for a period of time, the driveability issues seem to diminish. This condition may also cause an increase in crankcase pressure, creating oil leaks at seals and gaskets. Technicians may find one or more of the following DTCs set: • P0234 • P0236 • P0299 • P2227 • P00C7 Cause This condition may be caused by ice accumulation in the charge air cooler (CAC) or turbocharger wastegate regulator solenoid valve (TCV), causing improper boost pressures. Correction Important: The DTCs and symptoms above are not exclusively related to freezing/icing conditions. Only follow this bulletin when the condition is directly correlated with extreme cold of -18°C or less / 0°F or less. System leaks should always be ruled out first for P0299. Signs of moisture will always be present in the CAC system and are not a reliable indicator of freezing/icing. If any of the above conditions are present, allow time for possible ice build up in the CAC to melt by allowing the vehicle to thaw in a warm environment. Follow the Service Procedure below once the vehicle has had time to thaw. Page 2 October, 2022 Bulletin No.: 22-NA-007 Important: Service agents must comply with all International, Federal, State, Provincial, and/or Local laws applicable to the activities it performs under this bulletin, including but not limited to handling, deploying, preparing, classifying, packaging, marking, labeling, and shipping dangerous goods. In the event of a conflict between the procedures set forth in this bulletin and the laws that apply to your dealership, you must follow those applicable laws. Important: Allow time for the vehicle to thaw in a warm environment to avoid damaging or breaking parts that may be required to be re-installed. Service Procedure 4171562 1. Remove the CAC (2) and drain any moisture built up. Refer to Charge Air Cooler Replacement in SI. Important: Do Not perform an oil change if the oil change was recently done. • If the oil change was recently done and no signs of moisture have been confirmed, proceed to Turbocharger Wastegate Regulator Solenoid Valve (TCV) Thermo-Wrap procedure. • If the oil change was not previously done or moisture has been found in the oil, proceed to step 2. 2. Perform an oil change. Refer to Engine Oil and Oil Filter Replacement in SI. Turbocharger Wastegate Regulator Solenoid Valve (TCV) Thermo-Wrap 3686945 1. Remove the turbocharger wastegate regulator solenoid valve (TCV) (1). Refer to Turbocharger Wastegate Regulator Solenoid Valve Replacement in SI. 2. Drain the TCV by turning the valve upside down. 6055068 3. Using clean shop air regulated to 80-100 PSI, blow through all three ports (1, 2 & 3) for 5 seconds each. Bulletin No.: 22-NA-007 October, 2022 Page 3 Note: Check port #2 to assure the spring gets lifted off the seat. This will be determined by the compressed air not dead heading when applied to port #2. When applying air to this port a small amount of air should be observed at port #3 and even less air will be noticed at port #1. If this does not happen, the TCV plunger may have hardened deposits from hot operating conditions which will impede TCV plunger movement, and the turbocharger wastegate regulator solenoid valve should be replaced. ⇒ Repeat step 3 twice. 6055077 4. Prior to reinstalling the TCV, pre-position the thermal wrap. This will aid in installation of the wrap once the TCV is reinstalled. 6046314 Note: The end result of the wrap will surround the TCV as shown in the graphic above. Do not snap the wrap until step 6. 5. Install the TCV. Refer to Turbocharger Wastegate Regulator Solenoid Valve Replacement in SI. 6046334 6. Once the mounting bolt and hoses are properly installed, pull the lower portion of the wrap upward, and snap it into position. 7. Clear all DTCs using GDS and evaluate. Page 4 October, 2022 Bulletin No.: 22-NA-007 Turbocharger/Supercharger Boost Pressure Sensor Inspection Important: Only perform steps 1-5 if DTC P0299 or P0234 is set. 4108751 1. Remove the turbocharger Air Pressure sensor (3). Refer to Turbocharger/Supercharger Boost Pressure Sensor Replacement in SI. 4910683 Important: Due to the sensitivity of the sensor, Do Not use any chemical cleaners including water and Do Not use compressed air to remove contaminates. 2. Inspect the sensor for any contaminates. Bulletin No.: 22-NA-007 October, 2022 Page 5 5020216 3. Allow time for any ice build-up to melt by placing the sensor port down. 4. Clean the sensor with a clean towel. 5. Install the sensor. Refer to Turbocharger/ Supercharger Boost Pressure Sensor Replacement in SI. Engine Control Module Programming for 2018–2022 Models Important: Updated Engine Control Module calibration: The updated calibration will enable a revised transmission shift pattern during cold weather operation which does not use overdrive as frequently. As a result, the customer may notice elevated engine RPMs during highway operation. This operating mode will reduce the potential for ice to build up inside the charge air cooler, and the potential for setting P0299 or P0234 diagnostic codes. Caution: Before downloading the update files, be sure the computer is connected to the internet through a network cable (hardwired). DO NOT DOWNLOAD or install the files wirelessly. If there is an interruption during programming, programming failure or control module damage may occur. • 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 12V jumper or booster pack disconnected from the AC voltage supply. DO NOTconnect 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. • Please verify that the radio time and date are set correctly before inserting USB drive into vehicle for programming, otherwise an error will result. • 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. Page 6 October, 2022 Bulletin No.: 22-NA-007 Caution: Be sure the VIN selected in the drop down menu (1) is the same as the vehicle connected (2) before beginning programming. 5743643 Important: If the vehicle VIN DOES NOT match, the message below will be shown. 5877000 Bulletin No.: 22-NA-007 October, 2022 Page 7 5644477 Important: Techline Connect screen shown above. Important: If the same calibration/software warning is noted on the TLC or SPS Summary screen, select OK and follow screen instructions. After a successful programming event, the Warranty Claim Code (WCC) is located in the Service Programming System dialogue box of the SPS Summary screen. Document the WCC on the job card. No further action is required. Refer to the Warranty Information section of the bulletin. 1. Reprogram the ECM. Refer to K20 Engine Control Module: Programming and Setup in SI.
