Service Bulletin Bulletin No.: 18-NA-020 Date: April, 2020 TECHNICAL Subject: Malfunction Indicator Lamp Illuminated with DTC P0300 and/or P0299/P2227 Set This Bulletin replaces PIP5511A. Please discard PIP5511A. Brand: Model: Buick Envision Chevrolet Equinox GMC Terrain Model Year: from to VIN: from to Engine: Transmission: Equipped with 2.0L Engine (RPO LTG) 2016 2020 2018 - - Equipped with 2.0L or 1.5L Engine (RPOs LTG, LYX) All Involved Region or Country U.S. and Canada Condition Some customers may comment on a malfunction indicator lamp illuminated. During diagnosis, a technician may find DTC P0299, P2227, or P0300 set/stored. Cause This condition may be caused by a moisture build up inside the charge air cooler. Long drives through rainy conditions and/or high humidity conditions (heavy fog) can cause moisture to collect in the charge air cooler. A heavy acceleration can draw moisture into the engine causing DTC P0300. In cold temperatures, ambient and PCV moisture can freeze in the charge air cooler, restricting flow, and causing DTC P0299 and/or P2227. Correction Perform a smoke leak test of the charge air cooler, then follow the repair steps in the appropriate Service Procedure below, depending on the build date and vehicle outside temperature experience. Note: Charge Air Cooler Shutter is only to be used in northern states or provinces where temperatures are consistently 20°F/-7°C or less in the winter. Note: In rare cases where the addition of a charge air cooler shutter doesn't prevent CAC freezing, install the lower portion of the soft grill cover. Remove cover from the grill when temperatures are consistently above 20F/-7C. Note: DO NOT use the grill cover when towing, mountainous and/or during very hot ambient temperatures 86F/30C. If a customer comes in to have the mastic removed from the charge air cooler, install the new shutter at that time, and use the shutter installation labor time. Note: If the charge air cooler is frozen and/or contaminated, remove and wash it out. Use the add-on labor operation. Copyright 2020 General Motors LLC. All Rights Reserved.

The added shutter is activated to close and open based on temperature. 1. Perform a smoke leak test of the charge air cooler. 4597334 • If a leak is determined, replace the charge air cooler with the newly designed part. Refer to Charge Air Cooler Replacement in SI. • If there is NO leak, but a P0300, P0299 and/or P2227 are present, AND the vehicle was built ON or BEFORE March 1,2018, then replace the charge air cooler with the newly designed part. Refer to Charge Air Cooler Replacement in SI. • If there is NO leak, but a P0300, P0299 and/or P2227 are present, AND the vehicle was built AFTER March 1, 2018, refer to SI for further diagnosis. Important: DO NOT replace the CAC ducts as part of this repair unless there is evidence of damage and/or a leak from the CAC ducts. Important: In warmer climates with high humidity, P0300 may be set during extended highway driving due to the condensation of moisture in the charge air cooler. Installing the lower portion of the soft grill cover will help prevent this occurrence. The customer should remove the cover for non-highway driving or when pulling a trailer. Service Procedure Equinox, Terrain If the charge air cooler is icing in colder weather conditions, even after using the grill covers, OR the temperature is expected to be consistently below 20°F/ -7°C, install a shutter in front of the Charge Air Cooler, following the steps listed below.
