ECM PROBLEM INSPECTION PROCEDURE

1. TEST ECM GROUND CIRCUIT: Measure resistance between ECM and chassis ground using the backside of ECM

harness connector as ECM side check point. If the problem is found, repair it.

Specification (Resistance): 1! or less

2. TEST ECM CONNECTOR: Disconnect the ECM connector and visually check the ground terminal on ECM side

and harness side for bent pins or poor contact pressure, If the problem is found, repair it.

3. If problem is not found in Step 1 and 2, the ECM could be faulty. If so, replace the ECM with a new one, and then

check the vehicle agaon. If the vehicle operates normally then the problem was likely with the ECM.

4. RE-TEST THE ORIGINAL ECM: Install the original ECM (may be broken) into a known-good vehicle and check the

vehicle. If the problem occurs again, replace the original ECM with a new one. If problem dose not occur, this is
intermittent problem (Refer to INTERMITTENT PROBLEM PROCEDURE in BASIC INSPECTION PROCEDURE).
