Inspection |
1. |
TCM ground circuit test : Measure the resistance between TCM and chassis
ground. (Inspect the terminal connected to the chassis ground with the
back of harness connector as the inspection point of TCM side.)
|
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. |
Reinspection of original TCM : Install the original TCM (probably broken)
into a known-good vehicle and check the vehicle. If the problem occurs
again, replace the original TCM with a new one.
If the problem does not recur, this is an intermittent problem and other
part may be faulty.
