Voltage Signal: Testing and Inspection

CIRCUIT DIAGRAM

HARNESS TEST
1. Disconnect the engine control module connector and turn the key to the START position.
2. Using a voltmeter, check the voltage between the engine control module harness connector terminal 8 and ground.

Voltage: 8 or more Volts.

3. Turn the key to the OFF position and check for continuity between engine control module harness connector terminal 2 and ground.

Continuity: Should exist.

4. If any of the previous tests produce unsatisfactory results, the harness will need to be repaired or replaced. Once repairs have been completed, road test the vehicle to confirm that the repair has corrected the problem.
