Summary
TECHNICAL SERVICE BULLETIN: VOLUNTARY EMISSIONS SERVICE CAMPAIGN: FUEL TANK AND/OR PCSV CHECK VALVE INSPECTION/REPLACEMENT + ECU SW UPGRADE (SC288/SC288A) CLOSED & SUPERSEDED - This bulletin is now closed and superseded by SC356. This bulletin provided information to inspect the fuel evaporative system and, if necessary, replace the fuel tank and/or the Purge Control Solenoid Valve (PCSV) check valve on certain 2021-2024MY K5 (DL3a) vehicles equipped with a Gamma II 1.6L T-GDI engine, produced from March 27, 2020 through January 23, 2024. This bulletin also provides information to upgrade the ECU software logic. The subject vehicles may experience fuel tank swelling due to an issue with the PCSV check valve, which results in pressurized air to flow into the fuel tank. This may cause the Check Engine Light to illuminate, and in some cases, the engine to run rough, and/or an inability to refuel. These conditions may cause the vehicle to release air pollutant which exceed Federal and California standards.
