Fault codes
Dds: gear sensor diagnosis -> short circuit to ground or open circuit (s.C. Gnd or c.O.) - Short circuit to vdc (s.C. Vdc) - congruence (generic error - signal not correct).
Dashboard: the error "gear sensor" is shown on the service display. The eobd warning light activates.
Fault indication
If the dashboard receives the "gear" error information via the can line:
If the dashboard does not receive the gear or neutral engaged information via the can line:
If the dashboard receives incorrect gear engaged information (flashing dashes) via the can line with the engine running:
Warning
It is possible that the gear engaged or neutral engaged information is not being generated because the gear position self-acquisition procedure has not been performed (gear sensor not initialised).

Pin numbering of wiring harness side bbs unit connection.
Checks
The gear sensor is a hall effect unit. Ground is on pin 10 of the bbs unit, 5 v power is on pin 15 of the bbs unit, pin 13 of the bbs is the input for the signal generated by the sensor. Check that the sensor receives 5 v power.
Check the integrity of the electrical circuit and connections (short-circuits to ground, short-circuits to vdc, open circuits).
Perform the gear self-acquisition procedure.
If none of the aforementioned tests identify the problem, replace the gear sensor then perform the gear self-acquisition procedure. If the fault has not been resolved, replace the bbs unit.
Warning
The engine control unit uses the neutral engaged signal generated by the gear sensor, together with the clutch lever pulled signal, to manage idle speed.
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.
Gear self-acquisition procedure
The gear self-acquisition procedure must be launched from the dds instrument. This ensures that the data stored previously is deleted and enables the bbs to run a new gear acquisition procedure. With the engine running and the motorcycle in motion:
Carrying the maximum load allowed
Your motorcycle is designed for travelling over long
distances with a full load in complete safety.
Even weight distribution is critical to preserving these safety
features and avoiding trouble when performing sudden
manoeuvres or riding on bumpy roads.
Warning
Do not exceed the total permi ...
Overhauling the front forks
Note
It is advisable to loosen the top cap (14) when the fork is still fitted
to the motorcycle.
Note
The specific tools for the revision of the fork, are described in sect. 3
- 4, Specific tools for the frame.
Loosen the spring preload adjuster before unscrewing the plug (14).
