P1717

DTC P1717: Open in Transmission Range Switch ATP RVS Switch Circuit




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 RVS switch is OPEN with the shift lever in the R position while shifting between the P, R, and N positions, the PCM detects a RVS switch OPEN failure and a DTC is stored.

Enable Conditions

Malfunction Threshold
No RVS signal is detected with the shift lever in the R position while shifting between the P, R, and N positions.

Driving Pattern
1. Start the engine, and shift to the P, R, and N positions.
2. Shift to the R position, and wait for at least 320 milliseconds.

Diagnosis Details

Conditions for illuminating the MIL
When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the PCM memory. If the malfunction recurs during the next (second) drive cycle, the DTC and the freeze frame data are stored. The MIL does not come on.

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