Inspection |
1. |
TCM ground circuit test: Measure resistance between TCM and
chassis ground using the backside of TCM harness connector as TCM side check point.
|
2. |
TCM connector test: Disconnect the TCM connector and visually
check the ground terminals on TCM side and harness side for bent pins
or poor contact pressure. |
3. |
If problem is not found in Steps 1 and 2, the TCM could be faulty.
If so, replace the TCM with a new one, and then check the
vehicle again. If the vehicle operates normally then the problem was
likely with the TCM. |
4. |
The original TCM re-test : 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. If problem does not occur, this is problem of other parts. |
