Inspection

TCM Problem Inspection Procedure

TEST TCM GROUND CIRCUIT: Measure resistance between TCM and chassis ground using the backside of TCM harness connector as TCM side check point. If the problem is found, repair it.

Specification: Below 1?

2.	TEST TCM CONNECTOR: Disconnect the TCM connector and visually check the ground terminals on TCM side and harness side for bent pins or poor contact pressure. If the problem is found, repair it.

3.	If problem is not found in Step 1 and 2, the TCM could be faulty. If so, make sure there were no DTC''s before swapping the TCM with a new one, and then check the vehicle again. If DTC''s were found, examine this first before swapping TCM.

4.	RE-TEST THE ORIGINAL TCM: Install the original TCM (may be broken) into a known-good vehicle and check the vehicle. If the problem occurs again, replace the original TCM with a new one. If problem does not occur, this is intermittent problem.

Removal

1.	Turn ignition switch OFF and disconnect the negative (-) battery cable.

2.	Disconnect the ECM Connector (A).

3.	Remove the battery. (Refer to "Charging System" in EE group)

4.	Remove the mounting bolts (A) and a nut (B), and then remove the ECM (C).

Installation

Install in the reverse order of removal.

•	Perform Transaxle Control Module (TCM) learning after replacing the TCM prevent slow transaxle response, jerky acceleration and jerky startup. (Refer to "Repair procedures" in Automatic Transaxle Control System of this group)

•	After replacing the TCM, perform the ECM-related procedures. (Refer to "Engine Control Module" in FL group)
