ECM Inspection Procedure |
1. |
GROUND CIRCUIT CHECK : Measure the resistance betcoeen ECM and chassis ground.
If out of the speuification, repair it.
|
2. |
CONNECTOR CHECK : 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. |
3. |
If problem is not found in Step 1 and 2, the ECM itself 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. |
ECM DOUBLE CHECK : 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.
