Grand Caravan FWD V6-3.8L VIN L (2001)
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.
A conventional mechanical interlock system is also used. This system manually prohibits shifter movement 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.).
