FUEL INJECTION SYSTEM
EAS00899
ECU SELF-DIAGNOSTIC FUNCTION
The ECU is equipped with a self-diagnostic function to ensure the normal operation of the fuel injec-
tion system. If a malfunction is detected in the fuel injection system, the self-diagnostic function
immediately operates the engine with alternate operating instructions and the engine trouble warn-
ing light comes on to alert the rider of the malfunction. Once a malfunction has been detected, its
corresponding fault code is stored in the memory of the ECU.
• To alert the rider that the fuel injection system is not functioning, the engine trouble warning light
flashes when the start switch is pushed to start the engine.
• If a malfunction is detected in the fuel injection system, the ECU provides the proper alternate
operating instructions necessary to operate the engine and the engine trouble warning light
comes on to alert the rider of the malfunction.
• After the engine has been turned off, the lowest fault code appears on the odometer/fuel reserve
tripmeter/tripmeter 2 LCD. Once a fault code has been displayed, it remains stored in the mem-
ory of the ECU until it is deleted.
