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 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.
|
4. |
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 Inspection Procedure” in Basic Inspection Procedure).
