Gear Shift Lock Solenoid Control Circuit/Open
- Severity
- High
- Driving
- Drivable — book it in
An open circuit or general electrical fault in the gear shift lock solenoid circuit. This solenoid locks the selector lever in park until the brake pedal is pressed. Depending on which way the fault goes it either traps the lever in park, or - more seriously - stops locking it at all, so the lever can be knocked out of park without the brake being applied.
Possible causes
- CommonFailed shift lock solenoid
- CommonFaulty brake pedal switch, so the solenoid is never told to release
- CommonWiring or connector fault under the console
- PossibleBlown fuse on the circuit
- PossibleDrink or dirt in the selector assembly
- RareFailed control module driver
What you might notice
- Cannot move the selector out of park
- Selector moves out of park without the brake pedal pressed
- Brake lights not working as well
- Check engine light on
What to check, in order
- Check whether the brake lights work. The shift lock releases on the brake switch signal, so a brake switch fault is the most common cause and it announces itself at the back of the car.
- Test whether the lever moves out of park without the brake pedal pressed. If it does, the lock is not working and the vehicle should be parked with the handbrake firmly applied until it is repaired.
- Check the fuse for the circuit.
- Inspect the selector assembly for spilled drink - console selectors sit under cup holders.
- If the lever is trapped in park, the vehicle has a manual override release. Its location is in the handbook; use that to move the car rather than forcing the lever.
