Shift Position Interlock

Battery voltage is supplied at all times through Fuse 24 (in the under-dash 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 22 (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 Shift Lock Solenoid is then energized, allowing the shift lever to be moved from the PARK position.

While the vehicle is in forward motion, the PCM removes ground from the Shift Lock Solenoid. The Shift Lock Solenoid is then de-energized, which disables the shift lever from being moved to REVERSE or PARK.

Refer to the A/T INTERLOCK SYSTEM for specific tests and troubleshooting procedures.
