Shift Position Interlock
Battery voltage is supplied at all times through fuse 41 to the brake switch. With the ignition in
ON (II) or START (III), battery voltage is supplied through fuse 18 to the
shift lock solenoid. When you push the brake pedal, battery voltage is applied through the WHT/BLK wire to the transmission control module (TCM). If. at the same time, you do not push the accelerator pedal, a low voltage signal is sent through the RED/BLK wire to the
TCM. The TCM then applies voltage through the WHT/GRN wire to the shift lock circuit in the passenger's multiplex control unit. If the shift lever is in the PARK position, the shift lock circuit provides ground to the shift lock solenoid. The solenoid is then energized and the shift lever can be moved from the PARK position.
