BRAKE TRANSMISSION SHIFT INTERLOCK
MECHANISM
DESCRIPTION
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 (Fig. 37).
OPERATION
The system locks the shifter into the PARK posi-
tion. The Interlock system is engaged whenever the
ignition switch is in the LOCK or ACCESSORY posi-
tion. 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/brake
interlock cable is energized when the ignition is in
the RUN position. When the key is in the RUN posi-
tion and the brake pedal is depressed, the shifter is
unlocked and will move into any position. The inter-
lock system also prevents the ignition switch from
being turned to the LOCK or ACCESSORY position
(Fig. 38) unless the shifter is fully locked into the
PARK position.
