TEST TCM GROUND CIRCUIT: Measure resistance between TCM and chassis

TEST TCM CONNECTOR: Disconnect the TCM connector and visually
check the ground terminals on TCM 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 TCM could be faulty.
If so, make sure there were no DTC's before swapping the TCM with a
new one, and then check the vehicle again. If DTC's were found, examine
this first before swapping TCM.

RE-TEST THE ORIGINAL TCM: Install the original TCM (may be broken)
into a known-good vehicle and check the vehicle. If the problem occurs
again, replace the original TCM with a new one. If problem does not
occur, this is intermittent problem (Refer to “Intermittent Problem
