FUEL INJECTION SYSTEM

8-27

EAS30505

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 
number 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 while 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 meter display. This 

number 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 following conditions is present and the start switch is 

pushed:

Checking the engine trouble warning light

The engine trouble warning light comes on for around 2 seconds after the main switch has been set 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.

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 illumi-
nates 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.
