Ignition Lock Solenoid: Description and Operation
How the Circuit Works
Key Interlock
Voltage is supplied at all times to the key interlock switch through fuse 47. When you push the key into the ignition switch, battery voltage is provided to
the key interlock solenoid. If the A/T shift lever is in PARK, the park pin switch provides ground to the key interlock solenoid, energizing the solenoid
and allowing the key be turned to the LOCK (0) position.
Shift Position Interlock
Battery voltage is supplied at all times through fuse 47 to the brake switch. With the ignition in ON (II) or START (III), battery voltage is supplied
through fuse 8 (in the driver's under-dash fuse / relay box) to the shift lock solenoid When you push the brake pedal, battery voltage is applied through
the WHT / BLK wire to the PCM. 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 PCM. The PCM then applies voltage through the WHT / RED wire to the shift lock solenoid. If the shift lever is in the PARK position, the circuit
provides ground to the shift lock solenoid. The solenoid is then energized allowing the shift lever to be moved from the PARK position.
