Description

The ECU contains a built-in self-diagnosis system by which troubles with the engine signal network are detected and a check engine warning light on the instrument panel flashes.

By analyzing various signals as shown in the later table (See page FI-25 or 26) the ECU detects system malfunctions which are related to the various operating parameter sensors or actuator. The ECU stores the failure code associated with the detected failure until the diagnosis system is cleared by removing the fuse stop 1 5A (AE), EFI 1 5A (AT) or AM2 7.5A (AW) with the ignition switch OFF. The check engine warning light on the instrument panel informs the driver that a malfunction has been detected The light goes out automatically when the malfunction has been cleared.
