The ignition interlock system connects the automatic transmission shifter and the ignition lock system. With the ignition key in the LOCK or ACCESSORY position, the interlock system prevents the transmission from being shifted out of park. When the key is in the OFF or RUN position the shifter unlocks and can be moved to any gear position. The system also prevents the operator from turning the ignition key to the LOCK or ACCESSORY positions.
NOTE: If the vehicle has column shift, install a new interlock cassette (column shift) when replacing the ignition lock cylinder. Adjust the system after replacing the cassette. Refer to procedure in this group.
NOTE: If the vehicle has floor shift, adjust the interlock cable after replacing the lock cylinder.
The interlock cable slides into the housing behind the lock cylinder and attaches to the floor mounted shifter. The floor shift interlock system is adjusted by an integral locking clip in the interlock assembly. If the system requires adjustment and not replacement, refer to the Floor Shift Interlock Adjustment procedure in this Group.
