Abstract
An electronic control circuit of the type including a microprocessor, a circuit for monitoring the operational state of the microprocessor connected directly to a first output of the microprocessor, and a warning light of the control circuit and its input and output peripherals. The warning light is connected to a second output of said microprocessor through a starter and protection circuit and thus diagnostic data are available in series at the input terminal of said warning light which is also the output of said starter and protection circuit.
