The transmission range switch is attached to a control shaft. Shifting the transmission to each position/mode makes the control shaft rotate via the shift cable. The shift 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 transmission control module (TCM) 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 position/mode in R while shifting between P, R, and N, the TCM 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 position/mode 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 a loose or disconnected connector)
- Transmission range switch failure
- Shift cable adjustment failure
- TCM internal circuit failure
Confirmation Procedure
Operating Condition
- Start the engine.
- With the brake pedal pressed, shift the transmission to P, R, through N position/mode, then shift the transmission to R position/mode again, and wait for at least 320 milliseconds.
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the TCM memory. If the malfunction returns in the next (second) drive cycle, the shift position indicator blinks and a Confirmed DTC and the freeze data are stored. The MIL does not come on.
Conditions for clearing the DTC
The shift position indicator comes off by turning the vehicle to the OFF (LOCK) mode. The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool clear command.
