| DTC Code | DTC Name |
|---|---|
| P085011 | Park/Neutral Switch Circuit Short to Ground |
| P085015 | Park/Neutral Switch Circuit Short to Auxiliary Battery or Open |
DESCRIPTION
Instead of having a parking position as one of the positions as on a conventional shift lever, a P position switch (shift position indicator) is provided independently under the shift lever. The switch is a momentary type, in which the button does not lock mechanically.
The P position switch (shift position indicator) contains resistors R1, R2, R3 and R4. When the P position switch (shift position indicator) is not pressed, the switch provides a combined resistance of R3 and R4; and when the P position switch (shift position indicator) is pressed, the switch provides a combined resistance of R1, R2, R3 and R4. The voltage at the P1 terminal of the shift control ECU varies with the changes in the resistance of the switch. The shift control ECU determines the P position switch (shift position indicator) operation according to this resistance signal.

Tech Tips
After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the All Readiness check procedure.
Turn the power switch on (READY).
Depress the brake pedal and move the shift lever to select neutral (N).
Push the P position switch (shift position indicator) to select park (P).
