ABSTRACT:
An apparatus for detecting and indicating abnormality in an electronic control system for an internal combustion engine, which system includes an operation control unit operable on a supply voltage from a first power source to supply a plurality of output means with operation control signals dependent on the values of parameter signals detected by a plurality of input means. A plurality of abnormality detecting circuits detect abnormality in the operation of respective ones of the input and output means, and generate abnormality-indicative signals when abnormality is detected. A memory stores data of the abnormality-indicative signal supplied from the abnormality detecting circuits. Abnormality indicating circuit indicates the data stored in the memory. The memory is operable on a supply voltage from a second power source, and adapted to erase the data stored therein when it starts to be supplied with a supply voltage from the second power source.
