RECOVERY STRATEGIES
Various recovery strategies, characterised by a progressively increasing level of impact on vehicle
driving, are provided to ensure maximum driving safety while minimising inconvenience for the customer
in the event of a breakdown.
Depending on the impact the failure will have on the safe running/integrity of the engine, the indication
on the instrument cluster may be more or less obvious:
Level 1: error recognised, but not of safety significance and not noticeable to the driver => No indication
on the instrument cluster
Level 2: Safety-insignificant error but noticeable to the driver => Fixed warning light and display of
URGENT SERVICE message on the instrument cluster.
Level 3: error impairing safety => Flashing warning light and display of the message URGENT SERV-
ICE on the instrument cluster.
Four Recovery are possible depending on the severity of the technical problem detected:
1. Recovery Degraded Torque: torque and maximum engine speed are reduced, so as to avoid critical
driving situations or engine damage. Such a recovery is, for example, applied when one of the tracks
of the TPS or the DEMAND SENSOR fails.
2. Recovery Limp Home: the ECU manages throttle position, advance and injection time in such a
way as to keep the engine at a constant idle speed, regardless of the action on the throttle knob. The
rider is thus able to drive the vehicle to the repair shop (e.g. in the event of failure of both DEMAND
SENSOR tracks).
3. Recovery dead throttle valve: the throttle valve motor is switched off, the valve then moves to the
rest position (which is slightly open). In turn, the ECU manages the advance and injection time so as
to keep the engine at an accelerated idle speed. This recovery is applied, for example, when both traces
of the TPS are faulty or when the MAP sensor reading is implausible (throttle body off).
4. Recovery engine stop: The control unit shuts down the engine when it detects its own internal error
or finds that the throttle cannot be set to the accelerated idle position.
