* TCM judges with the priority-D>2>L>R>N>P
* No timing solenoid control for N-D
* No self-learning control
* No lockup
* No prevent reverse gear control

Conditions for Clearing the DTC

* The TCM turns off the MIL when no further failures are detected on the next ignition cycles.
* The scan tool can clear the DTC from the TCM history.
* The TCM clears the DTC from the TCM history memory after 40 consecutive ignition cycles without fault.
* The TCM detects single of the PNP switch.

Cause of Failure

* Wiring harness or connector between PNP switch and TCM
* PNP switch
