SHIFT INTERLOCK SYSTEM (Continued)
COLUMN
Vehicles equipped with a column shifter utilize a
brake transmission shift interlock (BTSI) solenoid,
which prevents the transmission gear shifter from
being moved out of PARK without a driver in place
(Fig. 371).

OPERATION

The Brake Transmission Shifter/Ignition Interlock
(BTSI) is engaged whenever the ignition switch is in
the LOCK or ACCESSORY position (Fig. 372). An
additional electrically activated feature will prevent
shifting out of the PARK position unless the brake
pedal is depressed at least one-half inch. A magnetic
holding device integral to the interlock cable is ener-
gized when the ignition is in the ON/RUN position.
When the key is in the ON/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 in the gated PARK position.
The following chart describes the normal operation
of the Brake Transmission Shift Interlock (BTSI) sys-
tem. If the "expected response" differs from the vehi-
cle's response, then system repair and/or adjustment
is necessary.
