Shift Interlock: Description and Operation
Ignition Interlock Cable Routing
Ignition Key Cylinder Actuation
The Brake Transmission Shifter/Ignition Interlock (BTSI), is a cable and solenoid operated system. It interconnects the automatic transmission floor
mounted shifter to the steering column ignition switch. The system locks the shifter into the PARK position. The Interlock system is engaged
whenever the ignition switch is in the LOCK or ACCESSORY position. An additional electrically activated feature will prevent shifting out of the
PARK position unless the brake pedal is depressed at least one-half an inch. A magnetic holding device in line with the park lock cable is energized
when the ignition is in the RUN position. When the key is in the RUN position and the brake pedal is depressed, the shifter is unlocked and will move
into any position. The interlock system also prevents the ignition switch from being turned to the LOCK or ACCESSORY position, unless the shifter
is fully locked into the PARK position.
