DTC P0705: Short in Transmission Range Switch Circuit (Multiple Shift-position Input)







General Description
The transmission range switch is attached to the control shaft. Operating the shift lever makes the control shaft rotate via the shift cable. The A/T gear position indicator indicates which position is selected according to the Low/High signal combinations which vary based on the control shaft rotational angle. The control shaft changes the position of the transmission range switch, activates the manual valve, and switches hydraulic pressure to shift the transmission through forward/neutral/reverse. The transmission range switch signal is used to determine the shift schedule. The voltage is 12 V (High) at the powertrain control module (PCM) input terminal when each transmission range switch position is Open, and it is 0 V (Low) when each switch is closed. If the PCM detects multiple switch inputs instead of the correct switch input for the selected range at that time, it detects a malfunction and stores a DTC.

Enable Conditions

Malfunction Threshold
Case 1
The PCM detects the selected range switch input and another range switch input simultaneously for at least 1 second.

Case 2
The PCM detects the P, R, or N range switch input and the FWD switch input simultaneously for at least 1 second.

Case 3
The PCM detects the D or L range switch input and the RVS switch input simultaneously for at least 1 second.

Driving Pattern
Start the engine, and then place the shift lever in each position for at least 1 second.

Diagnosis Details

Conditions for illuminating the MIL
When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the PCM memory.

Conditions for clearing the MIL
The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic runs.

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by disconnecting the battery.
