A failure-monitor system is described for an automotive control system comprising: a power source; a detector for detecting failure of elements of the control system and producing a fault signal identifying the faulty element; a memory for storing the fault signal identifying the faulty element; a display unit including indicators, each corresponding to one of the elements of the control system. The display unit associates with the memory for turning on one of the indicators corresponding to the faulty element identified by the contents of the memory. A reset signal generator associates with a preselected vehicle switch operated during normal vehicle driving, and is responsive to the vehicle switch being in a predetermined position to produce a reset signal for resetting the memory. A back-up circuit is responsive to the fault signal of the detector to connect the memory to the power source bypassing a system main switch.
