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.
|
3. |
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).
