Ranger 2WD V6-245 4.0L VIN X SFI (1997)
Shift Interlock Switch: Description and Operation
The switch prevents moving the shift lever out of PARK position unless brake pedal is depressed.
The brake-shift interlock system consists of an electrical solenoid mounted at the base of the steering column. If the key is in the RUN position, the
solenoid runs continually unless the brake is depressed.
Summary Of Interlock Operational Status
Key (ACC) & Steering Wheel Locked - Shift Unlocked - No Power to Solenoid
Key (LOCK) & Steering Wheel Locked - Shift Unlocked - No Power to Solenoid
Key (OFF) & Steering Wheel Unlocked - Shift Unlocked - No Power to Solenoid
Key (RUN) & Steering Wheel Unlocked - Shift Locked (Unless Brake Pedal Is Pressed) - Power to Solenoid
If the brake circuit fuse is blown or the solenoid has shorted internally, the vehicle will not shift from the PARK position even if the ignition is on and
brake pedal is pressed. The interlock can be temporarily overridden by the following procedure:
1. Apply parking brake.
2. Remove the ignition key.
3. Insert the ignition key and rotate one position clockwise (ignition off).
4. Shift the selector lever to neutral.
5. Start the vehicle.
NOTE: If the vehicle is shifted into PARK, the above procedure must be repeated.
