VOLUNTARY EMISSIONS SERVICE CAMPAIGN
SUBJECT:
FUEL TANK AND/OR PCSV CHECK VALVE
INSPECTION/REPLACEMENT + ECU SW UPGRADE (SC288)
This bulletin provides 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 October 17, 2023. 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.
Please note the replacement part(s) are not yet available. As soon as replacement part(s) become available,
this Technical Service Bulletin (TSB) will be updated with the proper inspection/replacement procedure,
replacement part(s) and labor op code information. Before conducting the procedure, verify that the vehicle
is included in the list of affected VINs.
 NOTICE

 NOTICE
•
Confirm a fully charged battery (12.3 volts or higher is necessary) is used or utilize a fully
charged jump starter box connected to the battery.
•
Ensure the KDS is sufficiently charged at 60% or higher prior to reflash.
•
All ECU upgrades must be performed with the ignition set to the ‘ON’ position unless otherwise
stated.
•
Damaged VCI II units should not be used and promptly replaced.
•
Be careful not to disconnect the VCI-II connected to the vehicle during the ECU upgrade
procedure.
•
DO NOT start the engine during ECU upgrade.
•
DO NOT turn the ignition key ‘OFF’ or interrupt the power supply during ECU upgrade.
•
When the ECU upgrade is completed, turn the ignition ‘OFF’ and wait 10 seconds before
