Abstract

PURPOSE:To perform optimum repairs by storing information on abnormality in the body of an automobile, an information transmission system and a control system to enable the reproduction of abnormal conditions. CONSTITUTION:Outputs of various sensors 2a-2f of an automobile are processed with a microcomputer 1, the output of which controls a fuel injector 3. When a manual switch 4 is operated, any input information during the period is stored into a non-volatile memory 5. The switch 4 is operated when a driver senses poor engine condition or any abnormality. Checking the contents of the memory 5 during the repairing enables discrimination of possible abnormality.
