Содержание

Fl SYSTEM CVT SYSTE FAIL SAFE FUNCTION Fl system CVT system is provided with fail safe function to allow the engine to start and the motorcy run in a minimum performance necessary even under malfunction condition ITEM Camshaft position sensor Crankshaft position sensor Intake air pressure sensor Throttle position sensor FAIL SAFE MODE When camshaft position signal has failed during running the ECM determines cylinder as before occurrence of such a failure The motorcycle stops Intake air pressure is fixed to 760 mmHg The throttle opening is fixed to full open position Ignition timing is also fixed Engine coolant temp sensor Intake air temperature sensor Atmospheric pressure sensor Ignition signal 1 IG coil 1 Engine coolant temperature value is fixed to 80 C Intake air temperature value is fixed to 40 C Atmospheric pressure is fixed to 760 mmHg 1 Ignition off Ignition signal 2 IG coil 2 2 Ignition off Injection signal 1 1 Fuel cut Injection signal 2 2 Fuel cut HO2 sensor E 02 19 Feedback compensation is inhibited Air fuel ratio is fixed to normal Current supply to motor is inter rupted Automatic mode Shifting to manual mode is inhibited Reduction ratio is fixed to an equivalent to 2nd range Manual mode During running on 2nd or higher range the reduction ratio is fixed to an equivalent to 2nd range If running on 1st range it is fixed to 1st range All shifting is inhibited CVT motor CVT pulley position sensor CVT speed sensor CVT secondary pulley revolution sensor CVT engine revolution signal CVT throttle position signal Throttle position signal is fixed to 30 open STARTING ABILITY NO RUNNING ABILITY YES Motorcycle can run but once en stops engine can not start NO NO YES YES YES YES YES YES YES YES YES YES YES YES 2 cylinder can run YES YES 1 cylinder can run YES YES 2 cylinder can run YES YES 1 cylinder can run YES YES YES YES YES YES YES YES YES YES YES YES YES YES The engine can start and can run even if the above signal is not received from each sensor But the running condition is not complete providing only emergency help by fail safe circuit In this case it is essary to bring the motorcycle to the workshop for complete repair
