5-16 FI SYSTEM
SELF-DIAGNOSIS FUNCTION
The self-diagnosis function is incorporated in the ECM. The function has two modes, “User mode” and
“Dealer mode”. The user can only be notified by the LCD (DISPLAY) panel and LED (FI light). To check the
function of the individual FI system devices, the dealer mode is prepared. In this check, the special tool is
necessary to read the code of the malfunction items.
USER MODE
*1
Current letter displayed any one of the Odometer, Tripmeter or
Clock.
*2
When one of the signals is not received by ECM, the fail-safe
circuit works and injection is not stopped. In this case, “FI” and
Odometer (*1) are indicated in the LCD panel and motorcycle
can run.
*3
The injection signal is stopped, when the crankshaft position
sensor signal, tip-over sensor signal, both #1/#2 ignition signals,
both #1/#2 injector signals, fuel pump relay signal or ignition
switch signal is not sent to ECM. In this case, “FI” is indicated in
the LCD panel. Motorcycle does not run.
“CHEC”: The LCD panel indicates “CHEC” when no communication signal from the ECM is received for 3
seconds.
For Example
: The ignition switch is turned ON, and the engine stop switch is turned OFF. In this case, the speed-
ometer does not receive any signal from ECM, and the panel indicates “CHEC”.
If CHEC is indicated, the LCD does not indicate the trouble code. It is necessary to check the wir-
ing harness between ECM and speedometer couplers.
The possible cause of this indication is as follows;
Engine stop switch is in OFF position. Side-stand/ignition inter-lock system is not working. Ignition
fuse is burnt.
NOTE:
Until starting the engine, the FI light turns ON.
The FI light is also turned ON when engine temperature is high or oil pressure is low.
