Kia Optima: Inspection
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). |
