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.
