Injection Stop Control
Self-Diagnosis Function
B822H11101002
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 indicator light). To check the function of the
individual FI system devices, the dealer mode is provided. 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 1 or tripmeter 2.
*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, ignition signal, #1,
#2, #3 and #4 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 and more.
Signal Descriptions
TIP-OVER SENSOR SIGNAL (FUEL SHUT-OFF)
When the motorcycle tips over, the tip-over sensor sends a signal
to the ECM. Then, this signal cuts OFF current supplied to the fuel
pump, fuel injectors and ignition coils.
OVER-REV. LIMITER SIGNAL
The fuel injector stops operation when engine rpm reaches rev.
limit rpm.
The fuel cut-off circuit is incorporated in this ECM in order to
prevent over-running of engine. When engine speed reaches 7
200 r/min, this circuit cuts off fuel at the fuel injector. But under no
load, the clutch lever is pulled or the gear position is neutral, this
circuit cuts off fuel when engine speed reaches 7 100 r/min.
CAUTION
!
Under no load, the engine can run over 7 100 r/min
though the fuel cut-off circuit is effective, which may
possibly cause engine damage. Do not run the engine
without load over 7 100 r/min at anytime.
