ABSTRACT:
An electronic control system for an engine of a vehicle is provided with an idling RPM set-point regulator to deliver at its output a nominal idling speed control signal, and a summer for combining the control signal with a modulating error signal which is generated in response to a detection of a defect in a component part of the vehicle. The modulated nominal control signal causes a corresponding change in the normal running of the engine during idling operation or during reduced load thus signalling to the operator a faulty condition. Additional warning means are provided for generating optical warning signals, and means for generating the modulating error signal to be supplied to the electronic control system when a defect occurs in the warning means.
