repair procedures

TEST

  1. TCM Ground Circuit Inspection: Measure the resistance between the TCM and body ground, using the rear of the TCM cable connector as the TCM-side test point.

    Specification: Less than 1 ohm

  2. TCM Connector Inspection: Disconnect the TCM connector and ground clamp. Visually inspect the terminals for bending or poor contact on the TCM side and the wire harness side.

  3. If no problem is found in steps 1 and 2, the TCM may be faulty. In this case, replace the TCM. Then recheck the vehicle. If the vehicle now operates normally, the cause of the fault was most likely a faulty TCM.

  4. Retest with Original TCM: Install a suspected faulty TCM removed from the vehicle into a known good vehicle and check whether the fault occurs. If it does, replace the TCM. If the problem does not occur, it is intermittent. Check for an intermittent malfunction. If the problem does not occur, the problem was caused by other parts.

expansion

  1. Disconnect the battery negative (-) cable.

  2. Remove the interior fuse block.

    (Refer to Body Electrical System - Junction Box (Passenger Footwell)).

  3. Disconnect the TCM connector (A).

  4. Loosen the nuts and remove the TCM (A).

Installation

  1. Installation is the reverse of removal.
