3-24 FUEL SYSTEM (DFI)
Troubleshooting the DFI System
The warning indicator light (LED) [A] is used for the FI
indicator, immobilizer indicator (equipped models) and oil
pressure warning indicator.
When a problem occurs with DFI system, the warning in-
dicator light (LED) [A] and FI warning symbol [B] blinks to
alert the rider. In addition, the condition of the problem is
stored in the memory of the ECU. For models equipped with
an immobilizer system, the warning indicator light (LED)
and immobilizer warning symbol [C] blinks, when a prob-
lem occurs in the 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 warning indicator
light (LED), FI and/or immobilizer warning symbols do not
blinks, and service code is not displayed.
