Power Locks - Service Information: Operation: Notes

The Power Lock System is operated with pneumatic supply lines connected to actuators at each power lock. Locking and unlocking is accomplished when the Body Control Module (BCM) is actuated by the Sentry Key Remote Entry Module (SKREEM). The BCM then transmits a signal to the Central Locking Pump/Security System Module via the Controller Area Network (CAN) bus. The Central Locking Pump/Security System Module incorporates a pump to supply pressure or vacuum and valves which direct the supply via pneumatic supply lines to the Power Lock System component.

For additional information about the BCM, SKREEM or Central Locking Pump/Security System Module functions as they relate to the power locks system, refer to ELECTRONIC CONTROL MODULES - SERVICE INFORMATION .
