OPERATION

DOOR ENTRY

The vehicle is entered by pushing the outside door handle. This will activate an electrical switch which is received by the Body Control Module (BCM). If the virtual state of the door is unlock, then the BCM will power the doors unlatch motor, activate the illuminated entry and smart glass function. If the outside door handle switch request is present more than 10 seconds, then a stuck fault will be stored in the BCM. A stuck outside handle will not prevent actuation from an inside handle signal.

DOOR EXIT

The vehicle is exited by pulling the inside door handle. This will activate an electrical switch which is received by the Body Control Module (BCM). The virtual lock state for this door will be set to unlock and BCM will power the doors unlatch motor and perform the smart glass function. If the handle is pulled far enough, then a cable will mechanically open the door. If the inside door switch request is present for more than 10 seconds, then a stuck fault will be stored in the BCM. If an inside door lock switch signal is active then inputs from the outside handle and door lock switch shall be ignored.

DOOR LOCK SWITCH

When the Body Control Module (BCM) receives an input from the lock switch indicating a door lock/unlock request is present, the BCM will set both doors of the vehicle to virtual lock or unlock. If the door lock switch request is present for more than 10 seconds then a fault will be stored in the BCM.

DOOR LOCK INHIBIT

If the key is in the ignition and either door is ajar, then a request to lock the vehicle shall be ignored when activating either door lock switch. Pressing the RKE lock/unlock button under these conditions shall result in a normal lock/unlock lock status.

AUTOMATIC DOOR LOCKS

This vehicle has a automatic door lock feature that will set the vehicle to virtual lock when certain conditions are set. This feature can be enabled or disabled by using the Scan Tool or by the customer. It is initially set to enabled. The vehicle is set to virtual lock when all the requirements listed below have been met:

- Vehicle speed is equal to or greater than 18 mph
- All doors are closed
- The engine controller has set the okay to lock doors
- The doors were not previously locked, via the power door lock switch or RKE when the ignition is in the run/start position

Once all conditions are met, the Body Control Module (BCM) will set the vehicle to virtual lock and send a message to the cluster indicating lock status. Once an automatic door lock has occurred, opening any door will reactivate the automatic door lock feature when the above listed conditions are again met.

KEY CYLINDER FUNCTION

The driver door key cylinder will allow the operator to perform a driver door entry, disarm the vehicle, set the vehicle to virtual unlock, activate the illuminated entry and Smart Glass function. The key cylinder switch has a separate resistively multiplexed input to the Body Control Module (BCM). This switch has two positions: Neutral (diagnostic) and Unlock.

The key cylinder is located on the drivers door below the outside mirror.

Turning the key towards the rear of the vehicle indicates an unlock signal to the (BCM). When an unlock input from the key cylinder is detected, the body controller will unlatch the driver door, activate the Smart Glass function, disarm the Vehicle Theft Alarm (VTA), activate the illuminated entry and set the vehicle to virtual unlock.

REMOTE KEYLESS ENTRY

The UNLOCK button will unlock either the drivers door or both doors if pressed twice.

When the Body Control Module (BCM) receives an unlock input, the park/tail lamps will flash one time to indicate the drivers door is unlocked, or will flash twice to indicate that both doors are unlocked, disarm the Vehicle Theft Alarm (VTA) and activate the illuminated entry.

Once the LOCK button is pressed, the horn will sound a short chirp to notify that the all door lock signal was received. When the Body Control Module (BCM) receives a lock input, both doors are locked, the horns chirp and the park/tail lamps are flashed on and off one time and initiates the Vehicle Theft Alarm (VTA) process.
