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.
