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

Battery voltage indicator (battery)
This function describes the battery voltage indicator. To access the function it is necessary to view the ""setting" menu", using buttons (1) "s" or (2) "t" select the "battery" function and press the reset button (3) to confirm. The information will be displayed as follows: if battery vol ...

Checking the camshafts and supports
Check the cam contact surfaces for scratches, grooves, steps and waving. Worn cams are frequently the cause of poor timing, which leads to loss of engine power. Place the camshaft between two centres and check the run-out on the areas indicated using two dial gauges. Service limit: 0.1 ...

Reassembly of belly fairing
Position the oil cooler shield (7) inserting the tab (a) into the slit (b) in the electrical components support (s). Note On refitting, make sure that the tab (c) remains positioned under the retainers (d) of the shield (7). Fit clips (11) on bracket (13) and orient them as shown in the f ...
