Shift Position Interlock
Battery voltage is supplied at all times through fuse 13 (in the under-hood fuse/relay box) to the brake pedal position switch. With the Ignition Switch in ON (II) or START (III), battery voltage is supplied through fuse 21 (in the under-dash fuse/relay box) to the Shift Lock Solenoid. When the Brake Pedal is pressed, a battery voltage input is supplied to the PCM and the MICU. If, at the same time, the accelerator pedal is not pressed, the PCM provides ground to the Shift Lock Solenoid. The solenoid is then energized allowing the Shift Lever to be moved.
