Inspection

Inspection

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.)

Specification : Below 1�©

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.
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.
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.
