A/T Shift Lock Control Solenoid Connector Terminal identification
Circuit/System Description
With the ignition in the ON position and the shift lever is in PARK, battery positive voltage is supplied from the body control module (BCM) to the automatic transmission shift lock control solenoid through the normally-closed automatic transmission shift lock control switch. When the transmission control module (TCM) indicates the shift lever is in the PARK position, the engine control module (ECM)/powertrain control module (PCM) sends a class 2 serial data message to the BCM indicating the transmission is in the PARK position. This allows current to flow through the switch to the automatic transmission shift lock control solenoid. Since the automatic transmission shift lock control solenoid is permanently grounded, the shift lock control solenoid energizes, locking the shift linkage in the PARK position. When the driver presses the brake pedal, the contacts in the automatic transmission shift lock control switch open, causing the automatic transmission shift lock control solenoid to de-energize, unlocking the shift lever from the PARK position.
