Gear Shift Lock Solenoid Control Circuit High

Severity: High
Driving: Drivable — book it in

The gear shift lock solenoid circuit is reading high - typically shorted to voltage or a lost earth. The module cannot control the park lock, so the lever may be trapped in park or may not be locked at all.

Possible causes

CommonWiring shorted to voltage or a lost earth between the module and the solenoid
CommonCorroded or damaged connector under the console
CommonOpen or shorted solenoid winding
PossibleBlown fuse on the circuit
RareFailed control module driver

What you might notice

Cannot move the selector out of park
Lever moves out of park without the brake pedal
Check engine light on

What to check, in order

Disconnect the solenoid and check whether the high reading persists at the harness.
Measure the solenoid winding resistance against specification.
Inspect the connector under the console.
Check the fuse and the brake switch circuit.
If the lever is trapped, use the manual override release described in the handbook rather than forcing it - forcing the lever breaks the detent mechanism and turns an electrical fault into a mechanical one.
