Operation

OPERATION

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.

NOTE: The power door locks and rear liftgate lock actuators are not serviced separately. They are part of the door lock or rear liftgate lock assemblies. Refer to Door Latch Assembly or Liftgate Lock Actuator for removal and installation information.

Central Locking

To operate Central Locking using the ignition key, turn the driver's door lock cylinder counterclockwise to lock and clockwise to unlock both doors, rear liftgate, and fuel door. Using the keyless entry transmitter, press the lock button to lock the doors, rear liftgate, and fuel door and the unlock button to unlock the doors (driver's door an fuel door only in selective mode), rear liftgate and fuel door. Using the power lock switch, press the upper portion to unlock and the lower portion to lock both doors, and the rear liftgate. Unlocking the vehicle with the ignition key or the keyless entry transmitter operates the Central Locking System and disarms the anti-theft alarm.

Remote Keyless Entry

The Remote Keyless Entry transmitter has four buttons for operation. They are UNLOCK, LOCK, PANIC, and IGNITION KEY RELEASE. Both the Lock and Unlock buttons have embossed ISO symbols. The Remote Keyless Entry transmitter has the ability to toggle the system between a Global mode or a Selective mode. The Unlock button when pressed will unlock the doors, rear liftgate and fuel door, and flash the turn signal lamps one time to indicate the vehicle is unlocked. The Lock button when pressed will lock the doors, rear liftgate and fuel door, and flash the turn signal lamps three times to indicate the vehicle is locked. If the lamps do not flash during locking, a door or the rear liftgate is not closed properly. The Panic button when pressed for at least one second will cause the exterior lamps to flash and a panic alarm to sound for three minutes. To deactivate, press the Panic button a second time or turn the ignition switch to the ON/RUN position. The Ignition Key Release button allows the key blade in the Remote Keyless Entry transmitter to flip open from the stored position.

The Sentry Key Remote Entry Module (SKREEM) transceiver is capable of retaining an access code even when power is removed. The module retains in memory the ID numbers of any Ignition Key transponder that is programmed into it. For added system security, each SKREEM is programmed with a unique secret key code. Additional and/or replacement keys can be obtained only from a Chrysler dealer.

Automatic Relocking Function

To avoid unlocking the vehicle unintentionally, the vehicle is automatically relocked by the Central Locking Pump/Security System Module via the SKREEM. Automatic Relocking takes place after the vehicle has been unlocked with either the Remote Keyless Entry Transmitter or the driver's door lock cylinder. The vehicle will be relocked if the SKREEM module doesn't receive a message within 40 seconds from any of the following:

- An open door signal.
- The key in the ignition sense.
- The power lock switch signal.
- The rear liftgate signal.

Automatic Locking

The power lock switch in the center console operates the automatic locking feature. With the ignition switch in the ON/RUN position, pressing and holding the upper portion of the power lock switch for at least five seconds activates automatic locking. With the automatic locking feature activated, the doors and rear liftgate will lock upon reaching a speed of approximately 15 km/h (9 MPH). If after automatic locking is active, the vehicle is unlocked with the interior power lock switch, this state is maintained until a door is opened, or until the ignition is turned off. Automatic locking is accomplished again only upon reaching the specified speed. The logic circuitry for automatic locking is integrated into the Central Locking Pump/Security System Module. The automatic locking feature can also be toggled or inhibited with the DRB III(R), for additional information see Toggling Customer Preferences.

Emergency Unlocking

In the event of a vehicle collision, the doors are unlocked automatically by a crash sensor integrated into the Central Locking Pump/Security System Module. The doors are unlocked after a delay time of 8 to 11 seconds. The emergency unlocking function interrupts all functions performed by the Central Locking Pump/Security System Module, which are reactivated only after interrupting the ignition. The emergency unlocking function is only active when the vehicle is unlocked from the outside.
