Abstract

A control system for electrical components of a motor vehicle has an emergency battery and emergency circuitry which, when the starter battery fails, connects the control unit to the emergency battery and cuts off comfort functions like window lifters while allowing the basic control mode to operate in which door locks, a theft alarm and a lid lock for the compartment containing the starter battery remain operative.
