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 engine 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 appropriate substitute characteristic operation, and alerts the rider of the detected malfunction by illuminating the engine trouble warning light.
After the engine has been stopped, the lowest fault code number appears on the odometer/trip meter/fuel reserve trip meter/clock LCD.
Once a fault code has been displayed, it remains stored in the memory of the ECU until it is deleted.

Checking the Engine Trouble Warning Light
The engine trouble warning light comes on for around 2 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.
If the warning light does not come on, under these conditions, the warning light (LED) may be defective.
ECU Detects an Abnormal Signal from a Sensor
If the ECU detects an abnormal signal from a sensor while the vehicle is being driven, the ECU illuminates the engine trouble warning light and provides the engine with alternate operating instructions 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 operating or stop operating, depending on the conditions.
