When an ECM is reflashed, initialized, or replaced, and the driveplate of the fly wheel has been replaced, follow these procedures to relearn the crankshaft position (CKP) system variation:
Caution: Before performing the Crankshaft Position System Variation Learning Procedure always set the vehicle parking brake and block the drive wheels in order to prevent personal injury. Release the throttle immediately when the engine starts to decelerate in order to eliminate over revving the engine. Once the learn procedure is completed, the control module will return engine control to the operator and the engine will respond to the throttle position.
