MOTOR VEHICLE TESTING CIRCIUTRY

摘要

A circuit arrangement for testing operating functions in motor vehicles by means of parallel circuits which contain at least one switching element conductive during a normal operating function and one control lamp and which are adapted to be closed by a test switch, and with one transmitter each coordinated to the operating functions which automatically triggers a warning indication with abnormal operating functions; at least one warning lamp for the warning indication which is independent of the control lamps is thereby provided in the circuit arrangement.
