Transaxle Control Module(TCM) Problem Inspection Procedure
| 1. |
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.
|
| 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 (Refer to “Intermittent
Problem Inspection Procedure” in Basic Inspection Procedure). |
