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
•
Be sure to read and follow the “General Safety Information
and Caution” before doing any work related with the high voltage
system. Failure to follow the safety instructions may result in serious
electrical injuries.
•
Be sure to shut off the high voltage circuit according to the
“High Voltage Shut-off Procedures” before doing any work related
with the high voltage system to avoid serious electrical injuries.
