Abstract
A method and a device for automatic detection of an equipment status of optional power consuming components, such as an air conditioning compressor, for an automobile are described. A signal formed in the automotive controller is monitored as a function of an engine load to determine whether the signal undergoes a certain change, for example, reaches a predetermined range, when an optional power consuming component is turned on, or power is demanded through corresponding switch operation, indicating the presence of the optional power consuming component, with the goal of achieving a permanent change in control data as a function of the automotive equipment present.
