Inspection Procedure

HARNESS INSPECTION

ECM Connector Pin Numbers (from Wire Side):




Pins number 13 and 26 must have a complete path to ground. If there is incorrect or incomplete conection of the engine control module's ground wire, the engine control module will not function correctly.




Test the ground wiring integrity by disconnecting the ECM harness connector from the ECM and probing pins 13 and 26 for continuity to ground.
