Introduction
The fuel pump, injectors and ignition coils are all powered via the injection relay. The relay also sends voltage to the engine control unit, which enables activation of the relay itself.
Component assembling position
A injection relay; b etv relay (throttle valve actuator motor), c radiator fan relay, d engine control unit.
Connection wiring diagram
Ccm engine control connection, t injection relay. 85 Brown/black - bn/bk injection relay activation, 87 brown/white-bn/w ecu input voltage, u direct power to injectors, ignition coils and fuel pump, r battery power (+30), 30 and 86 brown - bn.
In the event of fault
In the event of an injection relay fault, the engine stops (if running) or will not start. The relay is not commanded by the ecu.
Fault codes generated and possible correlated faults
Fault codes generated by the engine control unit and displayed by the dds (fuel injection relay diagnosis):
Note
Check integrity of electric circuit - short-circuit to vdc = with dashboard on, using a voltmeter, a voltage is measured between the wire tested and ground.
Check integrity of electric circuit - short-circuit to ground = with the battery cables disconnected, using an ohmmeter, continuity is detected between the wire tested and ground.
Check integrity of electric circuit - open circuit = with the battery cables disconnected, using an ohmmeter, no continuity is detected between the two ends of the wire tested.
The dashboard service display shows the error "fuel injection" and the eobd warning light activates.
Possible correlated faults: the engine stops (if running) or will not start. Check:
Using the dds, activate the ignition coils, the fuel pump or the injectors. The injection relay is driven and its contacts (pin 87 and pin 30) should close.
If none of the aforementioned tests identify the problem and the relay is in proper working order, replace the engine control unit.
Component replacement methods
No special measures are necessary in order to replace the injection relay.
Distance travelled on fuel reserve: trip fuel
This function shows the distance travelled on fuel reserve (in
km or miles depending on the specific application).
When the fuel light comes on, the display automatically
switches to the "trip fuel" indicator.
Trip fuel reading remains stored even after key-off until the
vehicle i ...
Riding mode customisation
This function customises each riding style.
To access the function it is necessary to view the "setting"
menu page 48, using button (1, fig. 14) ?
or (2, fig. 14)

Front brake lever
Pull the lever (1, fig. 94) Towards the twistgrip to operate the
front brake. The system is hydraulically assisted and you only
need to pull the lever gently.
The control lever (1, fig. 94) Features a dial adjuster (2, fig. 94)
For lever distance from the twistgrip on handlebar
adjustment.
