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 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.

[ ]: HDS Parameter
Malfunction Threshold
One of these conditions occurs.
- The PCM detects the selected range switch input and another range switch input (except FWD switch input [FORWARD SWITCH (ATPFWD)]) simultaneously for at least 1 second.
- The PCM detects the P, R, or N range switch input [A/T P, R, or N SWITCH] and the FWD switch input [FORWARD SWITCH (ATPFWD)] simultaneously for at least 1 second.
- The PCM detects the D or S range switch input [A/T D or S SWITCH] and the RVS switch input [REVERSE SWITCH (ATPRVS)] simultaneously for at least 1 second.
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 line short to ground
- Transmission range switch failure
- PCM internal circuit failure
Confirmation Procedure
With the HDS
None.
With the Driving Pattern
- 1.
Start the engine.
- 2.
With the brake pedal pressed, place the shift lever in each position for at least 1 second.
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory.
Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.
