System Features
- The Central Locking system of ZKE V controls the door lock, trunk lock and Fuel Filler Flap actuators.
- The familiar single/double locking strategy is maintained from previous systems with the introduction of a new style door lock mechanism combined with dual actuator motors.
The new style actuators are sealed, self contained units with no replaceable parts. The door lock actuators use hall effect sensors in place of pin contacts and microswitches to provide:
- Door lock key position (driver's door only),
- Door open/closed status (replaces door jamb switch).
The mechanical interior lock rods only lock the actuator they control. There is no affect on the central lock control of other doors. The rear doors are equipped with the child lock out lever preventing the door from being opened from the inside regardless of the actuators position.
- A new automatic locking feature activates the door lock actuators when a road speed signal of 2.5 MPH is detected via the K-Bus. The factory default encoding of this feature is off, but can be encoded on for individual users with the Key Memory function.
- The Driver's door lock location is the only point outside of the vehicle where the key can mechanically control all of the central locking system functions. The outside locks (driver's door and trunk) incorporate the familiar overrunning lock cylinder that breaks away and freewheels if an attempt is made to destroy the lock with a screwdriver, dent puller, etc.
- The trunk can be locked/unlocked with the key but does not lock/unlock the entire vehicle as on previous systems. When unlocked, the trunk can be opened by depressing the trunk release switch pad located above the license plate or from the remote trunk button in the left kick panel as on previous systems. Pressing the trunk release button on an FZV key also opens the trunk.
- GM V and EWS 3.3 interface via the K bus to monitor double lock status and to initiate double lock override. This feature allows the doors to be opened from the inside it an accepted EWS key is switched on in the ignition when double locked.
- The central locking switch is housed in a combined housing with the hazard flasher switch. Locking the vehicle from the central switch single locks the vehicle except for the fuel filler flap.
- Continuous locking/unlocking will initiate a timed arrest of the locking system. The GM counts each time the locks are actuated. After approximately 12 cycles, the timed arrest is active. The timed arrest is deactivated one actuator cycle for every 8 seconds until the counter is reset to 0. The timed arrest is overridden if a crash signal is received from the MRS II.
- The selective unlocking feature of the E38/E39 is maintained on the ZKE V. A single unlock request from the driver's door with the key or via the remote transmitter unlocks the driver's door only. A second unlock request unlocks the remaining doors and trunk. This feature can be modified for individual users with the new Key Memory capabilities to activate all lock actuators simultaneously.
