17-18 SELF-DIAGNOSIS SYSTEM
Self-Diagnosis
Note:
 (*1): Limp Home Mode: when parts related the ETV malfunctioned, backup methods are used in
       ECU control.
          (*1-1) Limp Home Mode 1: Mode to press a rider for repair. Limit engine power to lower than
       that of when normal.
          (*1-2) Limp Home Mode 2: Mode to restrict riding. The ECU does not accept throttle operation
       signals and considers the throttle is fully closed.
          (*1-3) Limp Home Mode 3: Mode to evacuate to a repair shop. The ECU stops controlling the
       ETV and manages engine output by controlling fuel injection and ignition timing. Engine power
       is limited to lower than that of when normal.
 (*2): D-J Method: When the engine load is light like at idling or low speed, the ECU determines the
       injection quantity by calculating from the throttle vacuum (intake air pressure sensor output volt-
       age) and engine speed (crankshaft sensor output voltage). This method is called D-J method.
 (*3): α-N Method: As the engine speed increases, and the engine load turns middle to heavy, the
       ECU determines the injection quantity by calculating from the throttle opening (throttle position
       sensor output voltage) and the engine speed. This method is called α-N method.
 (*4): Actuator Malfunction Backup Mode: When certain parts (the parts indicated in the table above)
       malfunctioned, the ECU set the special failsafe control; fuel cut, fuel quantity correction, ignition
       cut, ignition timing correction electric throttle valve specification correction.

    *: This depends on the number of stopped cylinders.

                                                   NOTE
  ○When inspecting the ECU connector, refer to the terminal numbers of the ECU connectors (see
    Terminal Numbers of ECU Connectors(3-16)).
