WHEN I SHUT OFF THE ENGINE THE ONLY DOOR THAT AUTOMATICALLY UNLOCKS IS THE DRIVERS DOOR
The power lock system allows all of the doors and liftgate to be locked or unlocked electrically by operating a switch on either front door trim panel. The power lock system receives non-switched battery current through a fuse in the Junction Block (JB), so that the power locks remain operational, regardless of the ignition switch position.
The instrument cluster locks the doors automatically when the vehicle speed exceeds 25.7 Km/h (15 mph), all doors are closed, and the accelerator pedal is depressed. The rolling door lock feature can be disabled through the EVIC.
This vehicle also offers several customer programmable features, which allows the selection of several optional electronic features to suit individual preferences.
The power lock system for this vehicle can also be operated remotely using the Remote Keyless Entry (RKE) transmitters.
The central locking system controls powered operation of the door and liftgate locks and the illuminated entry system. Central locking includes the following features:
- Automatic locking of the doors and liftgate when the vehicle speed exceeds approximately 25 km/h (15 mph).
- Locking prevention with a door lock switch or the RKE transmitter if the key is in the ignition switch and the driver’s door is open.
- Driver selectable unlocking mode: Unlock only the driver’s door or all doors and the liftgate with one press of the RKE transmitter unlock button. The driver’s door cylinder can also be used to unlock the door. One turn of the cylinder will unlock the driver’s door, two turns within five seconds will unlock all doors.
- Automatic illumination of interior courtesy lamps when the vehicle is unlocked.
- Locking all doors and the liftgate by pressing the lock button on the RKE transmitter, or by pressing a lock switch on one of the front doors.
DOOR LOCK MOTORS
The lock mechanisms are actuated by a reversible electric motor mounted within each door. The power lock motors are integral to the door latch units.
The power lock motors cannot be adjusted or repaired. If inoperative or damaged, the door latch unit must be replaced.
REMOTE KEYLESS ENTRY
The Remote Keyless Entry (RKE) system locks and unlocks the doors and liftgate, turns on interior lamps, and arms and disarms the Vehicle Theft Security System (if equipped). The RKE system operates on non-switched battery current through a fuse in the Integrated Power Module (IPM), so that the system remains operational regardless of the ignition switch position.
The RKE transmitters are also equipped with a Panic button. If the Panic button on the RKE transmitter is depressed, the horn will sound and the exterior lights will flash on the vehicle for about three minutes or until the Panic button is depressed a second time. A vehicle speed of approximately 25.7 kilometers-per-hour (15 miles-per-hour) will also cancel the panic event.
The RKE system can also perform other functions on this vehicle. If the vehicle is equipped with the optional Vehicle Theft Security System (VTSS), the RKE transmitter will arm the VTSS when the Lock button is depressed and disarm the VTSS when the Unlock button is depressed.
The RKE system includes two transmitters when the vehicle is shipped from the factory, but the system can retain the vehicle access codes of up to a total of eight transmitters. The transmitter codes are retained in the RKE module memory, even if the battery is disconnected. If an RKE transmitter is faulty or lost, new transmitter vehicle access codes can be programmed into the system using a scan tool.
This vehicle also offers several customer programmable features, which allows the selection of several optional electronic features to suit individual preferences. Customer programmable feature options affecting the RKE system include:
- Remote Unlock Sequence- Allows the option of having only the driver side front door unlock when the RKE transmitter Unlock button is depressed the first time. The remaining doors unlock when the button is depressed a second time within five seconds of the first unlock press. Another option is having all doors and liftgate unlock upon the first depression of the RKE transmitter Unlock button.
- Sound Horn on Lock- Allows the option of having the horn sound a short chirp as an audible verification that the RKE system received a valid Lock request from the RKE transmitter, or having no audible verification.
- Flash Lights with Lock and Unlock- Allows the option of having the park lamps flash as an optical verification that the RKE system received a valid Lock request or Unlock request from the RKE transmitter, or having no optical verification.
- Programming Additional Transmitters- Allows up to a total of eight transmitter vehicle access codes to be stored in the receiver memory.
Certain functions and features of the RKE system rely upon resources shared with other electronic modules in the vehicle over the CAN data bus network. For diagnosis of these electronic modules or of the data bus network, the use of a scan tool and the appropriate diagnostic information are required.
The instrument cluster locks or unlocks the doors when an actuation input signal from a door lock switch or Remote Keyless Entry (RKE) transmitter is received. The instrument cluster turns on the output drivers and provides a voltage level to the door lock motor for a specified time. All passenger doors can be locked or unlocked using a mechanical button mounted on the door trim panel. The drivers door can be locked or unlocked by using the key cylinder.
DOOR LOCK MOTORS
The door lock motors are controlled by the instrument cluster. A positive and negative battery connection to the two motor terminals will cause the motor to move in one direction. Reversing the current will cause the motor to move in the opposite direction.
REMOTE KEYLESS ENTRY
- LOCK: Pressing the LOCK button locks all doors, sounds horn (chirp) once if enabled, flashes the park lamps once if enabled, and arms the Vehicle Theft Security System (VTSS), if enabled. The chirp verifies that the instrument cluster has sent a message for door lock operation. If a door has not been closed before pressing the LOCK button, the vehicle may not be secured and the VTSS (if equipped) will not arm until the door is closed.
- UNLOCK: Pressing the UNLOCK button once will unlock the driver’s door first if enabled, flashes the park lamps twice if enabled, activates the illuminated entry system, and disarms the Vehicle Theft Security System (VTSS), if equipped. Pressing the UNLOCK button twice within five seconds will unlock all doors, if driver’s door first is enabled.
- PANIC: Pressing the PANIC button sounds the horns at half second intervals, flashes the exterior lamps, and turns ON the interior lamps. The panic alarm will remain on for three minutes or until either the PANIC button is actuated again or the vehicle speed exceeds 25.7 Km/h (15 mph) which will cancel the panic event.
