Consumer Cut Off/Overload Protection

General Functions of ZKE III

Consumer Cut Off
The Consumer Cut Off function interrupts battery voltage to circuits preventing inadvertent battery drain if one of these consumers were to remain activated. Circuits controlled by consumer cut off will be switched off as the GM enters into the sleep mode.




For example, the interior lights are connected to the consumer cut out circuit (KL 30) and can remain on if one of the control switches are left on. The consumer cut off will deactivate KL 30 to the interior lighting after 16 minutes (or with the DISplus/MoDIC).

The following circuits are controlled by consumer cut off:
- Map/Reading Lights
- Glove Box/Luggage Compartment Lights
- Transmission Range Indicator Light
- Overload Protection Relay for
- Power Seat Motors
- Steering Column Motors

Overload Protection




The seat and steering column motors receive operating power through the consumer cutoff/ overload protection relay module. The consumer cutoff signal from the GM signals the relay to maintain operating power to the consumers.

If the relay module detects an increase in amperage (overload) the relay will open. The relay module (K-72) is located in the electrical carrier behind the glove box. The relay is reset by switching the ignition "off for 16 minutes, disconnecting the relay or the DISplus/MoDIC.
