  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.)

Specification : Below 1©

  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.
  2. 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.

  3. 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.
