3-28 FUEL SYSTEM (DFI)
Troubleshooting the DFI System
  With the engine stopped and turned in the self-diagnosis
mode, the service code [A] is displayed on the LCD (Liquid
Crystal Display) by the number of two digits.
  If the problem is with the following parts, the ECU can
not recognize these problem. Therefore, the yellow engine
warning indicator light (LED) does not go on, and service
code is not displayed.
    Fuel Pump
    Fuel Pump Relay
    Stick Coil Secondary Wiring and Ground Wiring
    ECU Main Relay

   When the service code [A] is displayed, for first ask the
rider about the conditions [B] of trouble, and then start to
determine the cause [C] of problem.
   As a pre-diagnosis inspection, check the ECU for ground
and power supply, the fuel line for no fuel leaks, and for
correct pressure. The pre-diagnosis items are not indicated
by the yellow engine warning indicator light (LED).
   Don’t rely solely on the DFI self-diagnosis function, use
common sense.
