GROUND CIRCUIT TEST

1. Using an ohm meter, check for continuity between ground and ECM harness terminals 13 and 26.

Continuity Should Exist

If continuity does not exist, 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.
