The invention pertains to an apparatus (10) for diagnosing and displaying the condition of various components in an electro-mechanical vehicle or other system. The apparatus (10) includes command signal producing devices (12), control signal receiving devices (14), and means (16) for delivering control signals to the receiving devices (14) in response to receiving the produced command signals. The means (16) includes means (128) for receiving diagnostic command signals and displaying a predetermined diagnostic code in response to receiving a predetermined command signal. Both in-service and out-of-service diagnostics are provided for and a minimum of equipment external to the apparatus (10) is required, thus making the system both efficient and low in cost.
