Shift Interlock System
An ignition/shifter interlock mechanism is installed to prevent shifting the transaxle out of the PARK position unless the ignition switch is rotated to RUN and the brake pedal is applied. The floor shift interlock system consists of:
- an actuator assembly integral to the ignition/shifter interlock cable assembly.
- a bracket retaining the actuator.
- the necessary wiring.
The solenoid is energized when the ignition switch is turned to the RUN position, locking the transaxle range selector lever in the PARK position. When the brake pedal is applied and the stoplight switch (13480) is activated, the ignition/shifter interlock actuator is deactivated and the transaxle range selector lever can be moved out of the PARK position.

Action
- Shift Interlock System Does Not Release or Lock Properly
- Circuitry open/shorted.
- Blown fuse.
- Damaged stoplight switch.
- Damaged ignition/shifter interlock cable.
yes if not properly tightened the vibration and road conditions can loosen the terminal clamps
when removing the key from the ignition, the key symbol on the dash flashes five times, which refers to key coding ,I have three keys that all get the same response.I know that the security system also relates to key coding,is there a reset button for the security system?
