WARNING: Before performing crankshaft position system variation learn procedure, always set parking brake and block drive wheels in order to prevent personal injury. Release throttle immediately when engine starts to decelerate in order to eliminate over revving engine. Once learn procedure has been completed, control module will return engine control to operator and engine will respond to throttle position.

Battery must be fully charged and in good condition. Scan tool connection at Data Link Connector (DLC) should be clean and tight before starting crankshaft position system variation learn procedure.

  1. Close hood. Block drive wheels and set vehicle parking brake. Turn all accessories off. Start engine. Ensure engine is at least 158°F (70°C). Turn ignition off. Using scan tool, select and enable CRANKSHAFT POSITION SYSTEM VARIATION LEARNING PROCEDURE. Start engine.
