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.
|
2. |
TEST ECM CONNECTOR: Disconnect the ECM connector
and visually check the ground terminals on ECM side and harness side
for bent pins or poor contact pressure. If the problem is found, repair
it.

If problem is not found in Step 1 and 2, the ECM
could be faulty. If so, make sure there were no DTC's before swapping
the ECM with a new one, and then check the vehicle again. If DTC's were
found, examine this first before swapping 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 does not occur, this is intermittent problem (Refer to “Intermittent
Problem Inspection Procedure” in Basic Inspection Procedure).
