POWERTRAIN VERIFICATION TEST 

1. After repairs are complete, erase all DTCs with the scan tool.
2. With the scan tool, navigate to "Miscellaneous Functions" and perform all Relearn Procedures/Routines that are related to the component or system that was repaired.
   • NGC/GPEC CONTROLLER: The "Cam/Crank Relearn" Procedure  must be performed every time there has been a repair/replacement made to a CMP Sensor and/or CKP sensor, flywheel, valvetrain, timing chain or gears.
