FUEL INJECTION SYSTEM
7-29
EAS27350
ECU SELF-DIAGNOSTIC FUNCTION
The ECU is equipped with a self-diagnostic function in order to ensure that the fuel injection 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, the ECU provides an appro-
priate substitute characteristic operation, and alerts the rider of the detected malfunction by illuminat-
ing the engine trouble warning light.
• After the engine has been stopped, the lowest fault code number appears on the odometer/tripme-
ter/fuel reserve tripmeter/clock LCD. Once a fault code has been displayed, it remains stored in the
memory of the ECU until it is deleted.
Engine trouble warning light indication and fuel injection system operation
* The warning light flashes when any one of the conditions listed below is present and the start switch

Checking the engine trouble warning light
The engine trouble warning light comes on for 1.4 seconds after the main switch has been turned to
“ON” and it comes on while the start switch is being pushed. If the warning light does not come on under
these conditions, the warning light (LED) may be defective.
