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. |

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). |
