4-22 FI SYSTEM DIAGNOSIS ITEM FAIL-SAFE MODE STARTING RUNNING ABILITY ABILITY Secondary injection signal #1 Fuel-cut (secondary side) — “YES” #2, #3 & #4 cylinders can run. #2 Fuel-cut (secondary side) — “YES” #1, #3 & #4 cylinders can run. #3 Fuel-cut (secondary side) — “YES” #1, #2 & #4 cylinders can run. #4 Fuel-cut (secondary side) — “YES” #1, #2 & #3 cylinders can run. Secondary throttle valve Secondary throttle valve is fixed to actuator full close position. When motor dis- “YES” “YES” connection or lock occurs, power from ECM is shut off. STP sensor Secondary throttle valve is fixed to “YES” “YES” full close position. Gear position signal Gear position signal is fixed to 6th “YES” “YES” gear. PAIR control solenoid valve ECM stops controlling PAIR control “YES” “YES” solenoid valve. E EXCV actuator EXCV actuator is fixed to full open L position. When motor disconnection “YES” “YES” or lock occurs, power from ECM is shut off. P M The engine can start and can run even if the above signal is not received from each sensor. But, the engine running condition is not complete, providing only emergency help (by fail-safe circuit). In this case, it is nec- A essary to bring the motorcycle to the workshop for complete repair. When two ignition signals or two injector signals are not received by ECM, the fail-safe circuit can not work S and ignition or injection is stopped.
