Inputs and outputs of engine control unit and connection to can network


The diagram illustrates the inputs and outputs for the engine control unit. The signals from the brake buttons, the exhaust by-pass valve command signal and the gear sensor signal are transmitted over the can line.

1I emergency engine cutout switch

2I start button

4I side stand button

6I clutch button

7I battery voltage for congruence verification

8I power from ride-by-wire relay (etv)

9I oxygen sensor for horizontal cylinder

10I oxygen sensor for vertical cylinder

11I map sensor for horizontal cylinder

12I map sensor for vertical cylinder

13I main throttle grip position sensor

14I secondary throttle grip position sensor

15I main throttle valve position sensor

16I secondary throttle valve position sensor

17I engine temperature sensor

18I air temperature sensor

19I oil pressure switch (has no effect on any engine control strategy, but information is sent to dashboard via can line)

1U vertical and horizontal cylinder fuel injector

2U vertical and horizontal cylinder coil

3U electric ride-by-wire

4U injection relay (powers fuel pump, injectors and coils)

5U starter motor relay command

6U radiator fan relay command

7U ride-by-wire relay command

8U oxygen sensor heater for vertical and horizontal cylinder

1C connection with can network

Specific operating strategies
Idle speed No electric motor is used for idle speed regulation (bypass is modulated instead with the throttle valve), as idle speed control is effected by the ride-by-wire system. Idle speed is ma ...

Lap registration function
This function describes the "lap" time registration. If the function is activated (see "lap activation/deactivation description), the lap time can be registered as follows: Pressing the flash headlight button (11, fig. 12) The first time starts the "lap timer" for ...

Refitting the cooling system hoses and unions
Position the pump/radiator sleeve (22) and the radiator/radiator sleeve (23). Fit sleeve (23) and sleeve (22) to their corresponding fittings (n) and (o), and bring them fully home on collars (p). Note Sleeves (23) and (22) must be oriented so that the grooves (q) match the tabs (r) on fitt ...

Alternator
It is equipped with a 12 v, 430 w generator, consisting of a fixed element (stator, a) located on the generator cover and of a movable element (rotor, b) fixed to the crankshaft. Note To check the battery charging system for faults, use the dds diagnosis instrument and follow the instruct ...
