The transmission range switch is attached to a control shaft. Operating the shift lever makes the control shaft rotate via the shift cable. The A/T gear position indicator shows 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 high (5 V or 12 V) at the powertrain control module (PCM) input terminal when each transmission range switch position is open, and it is low (0 V) when each switch is closed. If the RVS switch is open with the shift lever in R while shifting between P, R, and N, the PCM detects an RVS switch open failure and stores a DTC.

[ ]: HDS Parameter
Malfunction Threshold
No RVS signal [REVERSE SWITCH (ATPRVS)] is detected with the shift lever in R while shifting between P, R, and N.
Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
- Transmission range switch ATP RVS line open (includes connector loose connection or disconnection)
- Transmission range switch failure
- Shift cable adjustment failure
- PCM internal circuit failure
Confirmation Procedure
Operating Condition
- Start the engine.
- With the brake pedal pressed, shift to P, R, through N, then shift to R again, and wait for at least 320 milliseconds.
With the HDS
None.
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, a Confirmed DTC and the freeze data are stored. The MIL does not come on.
Conditions for clearing the DTC
The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the 12 volt battery.
