Power Locks - Description

DESCRIPTION

POWER LOCKS

Electric door latches are used to accomplish opening and closing of the vehicle doors and electronics to accomplish the lock function. There are cables on the driver and passenger inside handles and the driver's door key cylinder that can open the doors in case of a power failure.

The lock status of the vehicle is a virtual lock, that is, the Body Control Module (BCM) monitors which door is considered locked, and will ignore the outside handle input on the door.

The BCM will send a message to the cluster that will identify if any one or both doors are unlocked. If only one door is unlocked, then DOOR UNLOCKED in the odometer display will blink continuously. DOOR UNLOCKED will remain steadily on in the odometer display if both doors are unlocked. No message will be displayed if both doors are locked.

DOOR ENTRY INHIBIT

Once the vehicle is started and driven to a speed of 8 to 13 Km/h (5 to 8 mph) then any actuation by the door inside or outside handles will be ignored. This has no effect on the virtual lock status of the vehicle.

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 the door will be set to unlock and BCM will power the doors unlatch motor. If the handle is pulled hard 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 a Passenger inside door lock switch signal is active then inputs from the outside handle and door lock switch shall be ignored. The Driver door outside handle has a separate input and works independently from the inside handle and lock switch.

REMOTE KEYLESS ENTRY

This vehicle utilizes a Remote Keyless Entry (RKE) module that has a serial link to the Body Control Module (BCM). The RKE system allows locking and unlocking as well as arming and disarming of the security system with a hand held transmitter.
