Shift Interlock: Description and Operation

When the ignition switch is in the RUN or CRANK position, the shift interlock system prevents the driver from shifting the vehicle from park unless the brake pedal is depressed. Once the brake pedal is depressed, the solenoid is de-energized. The restructure arm moves clear of the shift lever arm, allowing the gear selector to operate normally.

The shift interlock system can be overridden and the vehicle can be shifted by turning the ignition switch to OFF. This removes battery voltage at the solenoid, leaving it de-energized.
