Power Locks: Description and Operation
HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMSThe handles, locks, latches and entry systems consist of the components:
- liftgate latch
- liftgate lock cylinder
- generic electronic module (GEM)
- door latch
- hood latch
- remote keyless entry (RKE) transmitter
The passenger compartment doors are of a conventional latch-to-striker plate design with the striker located on the B and C pillars with a built-in door ajar switch.
The hood and liftgate striker plates locate into latches positioned in the vehicle body.
The hood can only be opened by operating the hood release cable handle situated in the instrument panel lower panel.
The liftgate/luggage compartment lid can be opened by a release switch located in the instrument panel. They can also be opened with the key in the liftgate/luggage compartment lid lock cylinder, by pressing the liftgate/luggage compartment lid release switch on the RKE transmitter or, on the wagon only, pressing the exterior liftgate release switch on the liftgate.
The door latch mechanisms are operated by a conventional actuating rod and cable system connected to the interior and exterior door handles.
The power lock system consists of the components used in the manual door lock system and includes the power door lock switches, power door lock actuator, circuit wiring and circuit protection.
The door handle and latch are removed from the inside of the door panel. The handle and latch cannot be removed separately. The actuating rods and latches are covered inside the door by a security shield.
The RKE transmitter operates the following functions:
- unlocking and locking the driver door
- unlocking and locking all doors
- unlocking and locking the liftgate
- arms and disarms the anti-theft alarm system
- deactivates a triggered alarm
- activate and deactivates the panic alarm
The RKE transmitter has a minimum operating range of 10 m (33 feet).
Inputs and Outputs
The RKE system receives inputs from the following:
- ignition switch (positions I and II)
- door ajar switches
- hood ajar switch
- interior liftgate/luggage compartment lid release switch
- exterior liftgate switch (wagon only)
- RKE transmitter
- anti-theft liftgate alarm inhibit switch
The RKE system distributes outputs to the following:
- GEM
- door lock actuators
- indicator LED
- parking lamps
- vehicle horn
RKE transmitter
The RKE system is completely independent in function but fully integrated within the GEM. The RKE system consists of a RKE transmitter and an antenna (radio frequency system).
The RKE transmitter for the radio frequency system operates without the RKE transmitter being directed at the vehicle. The normal range between the RKE transmitter and the antenna is 10 m (33 ft).
Before the RKE control system can be used, each RKE transmitter must be initialized to the vehicle. A maximum number of 4 RKE transmitters can be initialized to any vehicle. All RKE transmitters must be initialized at the same time.
The RKE system will not operate with the ignition lock cylinder in the RUN position.
Locking and Unlocking
The RKE transmitter contains four buttons to operate the system.
Press the LOCK button once to activate the central locking system and the alarm system (if equipped).
Press the LOCK button twice within three seconds and a horn tone will be heard along with a flash of the direction indicators indicating that the doors are locked. If any of the doors are ajar, the horn sounds twice.
Press the UNLOCK button once to unlock the driver door and disarm the alarm system (if equipped).
Press the UNLOCK button twice within three seconds to unlock the remaining doors.
Press the LIFTGATE RELEASE button once to release the liftgate/luggage compartment lid. This function works only if the ignition is in the OFF or ACC position or the vehicle speed is less than 4 mph (7 km/h).
Press the PANIC ALARM button to turn on the personal alarm.
Press the PANIC ALARM button a second time to turn off the personal alarm. The personal alarm also turns off if the ignition switch is turned to the ON or RUN position, or after 2 minutes of operation.
With the key in the OFF/ACC positions, pressing the RKE transmitter LOCK and UNLOCK buttons simultaneously for a minimum of 4 seconds toggles the unlocking mode from single door unlocking to central unlocking. Pressing both buttons again for 4 seconds toggles back to single door unlocking mode. Mode change is indicated by 2 flashes of the park lamps.
