OPERATION
The Brake/Transmission Shift Interlock (BTSI)
Solenoid prevents the transmission shift lever from
being moved out of PARK (P) unless the brake pedal
is applied. The BTSI solenoid is hardwired to and
controlled by the Intelligent Power Module (IPM).
Battery voltage is applied to one side of the solenoid
with the ignition key is in either the ON/RUN or
START positions (Fig. 211). The ground side of the
solenoid is controlled by a driver within the IPM. It
relies on voltage supplied from the stop lamp switch
to the stop lamp sense circuit within the IPM to tell
when the brake pedal is depressed. When the brake
pedal is depressed, the ground circuit opens, de-ener-
gizing the solenoid. When the brake pedal is
released, the ground circuit is closed, energizing the
solenoid.
When the ignition key is in either the ON/RUN or
START positions, the BTSI solenoid is energized, and
the solenoid plunger hook pulls the shift lever pawl
into position, prohibiting the shift lever from moving
out of PARK (P) (Fig. 212). When the brake pedal is
depressed, the ground circuit opens, de-energizing
the solenoid. This moves the gearshift lever pawl out
of the way (Fig. 213), allowing the shift lever to be
moved into any gear position.

SHIFT INTERLOCK SOLENOID (Continued)

A conventional mechanical interlock system is also
used. This system manually prohibits shifter move-
ment when the ignition switch is in the LOCK or
ACC positions. Solenoid operation is not required in
these key positions. When the ignition key is in the
OFF position, the gearshift lever is unrestricted, and
able to move into any gear position (during towing,
dead battery, etc.).
For intended BTSI system operation, refer to the
following chart:

SOLENOID - TCC
DESCRIPTION
The torque converter clutch (TCC) solenoid is fas-
tened to the transaxle valve body, and its connector
protrudes through the transaxle case (Fig. 222).
OPERATION
The torque converter clutch solenoid is responsible
for controlling application of the torque converter
clutch. It is controlled by the Powertrain Control
Module (PCM), which determines when conditions
are acceptable for torque converter lock-up.
