TCM Problem Inspection Procedure |
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 any problems are not found in Step 1 and 2, the TCM could
be faulty. If so, make sure there are no DTCs before replacing the TCM
with a new one, and then check the vehicle again. If DTCs are found,
examine this first before replacing TCM. |
4. |
RE-TEST THE ORIGINAL TCM: Install the original TCM (with
possible fault) 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 an intermittent problem (Refer to
“Intermittent Problem Inspection Procedure” in Basic Inspection
Procedure). |
