FUEL SYSTEM (DFI) 3-25
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.
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 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 warning indicator light (LED) and FI warning symbol.
Don’t rely solely on the DFI self-diagnosis function, use
common sense.
Even when the DFI system is operating normally, the
warning indicator light (LED) and FI warning symbol may
blink under strong electrical interference. Additional mea-
sures are not required. Turn the ignition switch OFF to s top
the indicator light and symbol.
If the warning indicator light (LED) and FI warning symbol
of the motorcycle brought in for repair still blinks, check the
service code.
When the repair has been done, the FI warning symbol
goes off. But the service codes stored in memory of the
ECU are not erased to preserve the problem history. The
problem history can be referred using the KDS (Kawasaki
Diagnostic System) when solving unstable problems
