Shift Interlock Switch: Service and Repair
1998 Ford Taurus V6-3.0L DOHC VIN SSECTION Service and Repair
The shift interlock mechanism is to prevent shifting the transaxle out of the PARK position unless the brake pedal is applied. The shift interlock system consists of the following components:
^ An actuator assembly attached to the ignition switch.
^ Necessary wiring.
The actuator is energized when the ignition switch is turned to the RUN position. This locks the floor shifter in the PARK position.
When the brake pedal is applied and the stoplight switch is activated, the shift lock actuator is deactivated and the floor shifter can be moved out of the PARK position.
The ignition/shifter interlock cable locks the floor shift lever in the PARK position when the ignition switch is in the LOCK position. It also requires the floor shift lever to be in the PARK position to turn the ignition switch to the LOCK position.
