DTC P0705

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC P0705 Transmission Range Switch Circuit Malfunction (No Signal)

Conditions for Setting the DTC

* The transmission control module (TCM) detects no signal from the transmission range (TR) switch circuit for 28 s continuously from short of detection.
* No signal from the TR switch circuit.
* Vehicle speed is 30 km/h (19 MPH) or greater.

Action Taken When the DTC Sets

* The TCM will request the illumination of Hold/Malfunction Indicator Lamp (MIL) and store the DTC when the TCM detects failures on 2 consecutive ignition cycles.
* The TCM judges the D range
* 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/Malfunction Indicator Lamp (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 D range of the TR switch.

Diagnostic Aids

Failure caused by:

* The wiring harness or connector between the TR switch and the TCM
* The TR switch
* The TCM
