General Functions of ZKE IV

Consumer Cut Off
The Consumer Cut Off function interrupts battery voltage to circuits preventing inadvertent battery drain if one of the consumers were to remain activated. The GM will deactivate the interior lights after 16 minutes if one of the doors is left open. Convertibles also have the following lighting circuits controlled by this feature:
- Glove Box Light
- Trunk Light

The circuit will switch back on when any monitored wake up trigger such as the door contacts or the lock/unlock signals become active.

Overload Protection
The Central Locking circuit of the GM is protected against overloads and short circuits by the electronic Overload Protection which is an integral part of the GM.

- Power protection for the door locking circuit is provided by a "time monitored" activation of the door lock actuators by the GM. The door lock actuators are provided power for the duration of time needed to run the actuator to the desired position. The maximum on time for the actuators is 0.7 seconds.
