Shift Interlock: Description and Operation

With the engine running or the starter switch in the ON or START position and the transmission control lever in the "P" position, the lever cannot be shifted from "P" to another position unless the brake pedal is depressed. A signal is sent through the parking position detecting switch to the shift lock controller and the shift lock solenoid energizes preventing the transmission control lever from being moved. When the brake pedal is depressed, a signal is sent to the shift lock controller. The shift lock controller then deenergizes the shift lock solenoid and allows the transmission control lever to be moved.
