FUEL INJECTION SYSTEMFI
EAS00899
ECU’S SELF-DIAGNOSTIC FUNCTION
The ECU is equipped with a self-diagnostic function in order to ensure that the engine control system is
operating normally. If this function detects a malfunction in the system, it immediately operates the en-
gine under substitute characteristics and illuminates the engine trouble warning light to alert the rider
that a malfunction has occurred in the system. Once a malfunction has been detected, a fault code is
stored in the memory of the ECU.

To inform the rider that the fuel injection system is not functioning, the engine trouble warning light
flashes when the start switch is being pushed to start the engine.

If a malfunction is detected in the system by the self-diagnostic function, this mode provides an ap-
propriate substitute characteristic operation, and alerts the rider of the detected malfunction by illumi-
nating an engine trouble warning light.

After the engine has been stopped, the fault code number appears from the lowest value in order of
precedence on the LCD meter. Once a fault code has been displayed, it remains stored in the memory
of the ECU until it is deleted.
