EAS27380 SELF-DIAGNOSTIC FUNCTION TABLE If the ECU detects an abnormal signal from a sensor while the vehicle is being driven, the ECU illu- minates the engine trouble warning light and provides the engine with alternate operating instruc- tions that are appropriate for the type of malfunction. When an abnormal signal is received from a sensor, the ECU processes the specified values that are programmed for each sensor in order to provide the engine with alternate operating instructions that enable the engine to continue to operate or stop operating, depending on the conditions. Self-diagnostic function table Communication error with the meter 6 - 6 FUEL INJECTION SYSTEM FI FI Fault code No.
