On Vehicle Inspection: Inspection

  1. TCM ground circuit test: Measure the resistance between TCM and chassis ground.

    (Inspect the terminal connected to chassis ground with the back of harness connector as the inspection point of TCM side.)

    Specification:  Below 1 Ω

  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 a 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 operated properly, 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 reoccur, this is an intermittent problem and other part may be faulty.
