Fault-Tracing

Fault-tracing

Checking the diagnostic trouble codes (DTCs)
Check whether the transmission control module (TCM) has stored any diagnostic trouble codes for improper adjustment of the gear shift position sensor. If diagnostic trouble codes (DTCs) are stored in the control module, these must be remedied and erased first.

Yes - No Fault Found

No - Checking the function

-------------------------------------------------

Checking the function
Start the readout to check that status of the signal coming from the transmission control module (TCM).
Move the gear selector to any position other than P or N. Check that the status of the signal indicates that the gear selector is not in position P or N.
Check the cable between the transmission control module (TCM) and the engine control module (ECM). Check for a short-circuit to supply voltage. Check the signal cable for loose connection, contact resistance and oxidation.
Also check the intermediate connectors. Check for contact resistance and oxidation
Remedy as necessary.
