1. |
TEST TCM GROUND CIRCUIT: Measure resistance between TCM and chassis
ground using the backside of TCM harness connector as TCM side check
point. If the problem is found, repair it.
|
2. |
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.
|
3. |
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
