The Central Locking Pump/Security System Module (3) uses a combination of electrical wires (2) and air pressure/vacuum lines (1). The Central Locking Pump/Security System Module is located in the right rear of the luggage compartment underneath the trunk floor covering (4). It is wrapped in a sound deadening material in order to operate quietly without disturbing the vehicle operator.

The Central Locking Pump/Security System Module controls the air and vacuum lines that handle the locking and unlocking of the vehicle doors, the liftgate, and the fuel tank door.
