DTC P0706 (Europe or N. American Emissions)

DTC Descriptor

This diagnostic procedure supports the following DTC:

- DTC P0706 Transmission Range Switch Circuit Malfunction (Short).

Conditions for Setting the DTC

- The transmission control module (TCM) detects more than 2 or more signals from the park/neutral position (PNP) switch circuit for 2 seconds continuously.
- Detection continuously occurs 5 times.

Action Taken When the DTC Sets

- The TCM will request the illumination of hold lamp and store the DTC when the TCM detects failures on 2 consecutive ignition cycles.
- The 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 preventative reverse gear control.

Conditions for Clearing the DTC

- The TCM turns OFF the hold lamp when no further failures are detected on the next 3 consecutive 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 "D range" signal from the PNP switch.

Cause of Failure

- The wiring harness or connector between the PNP switch and the TCM.
- The PNP switch.
- The TCM.
