RSV4 RR-RF
When sensors (3) detect a significant speed difference between the rear and the front wheels (for
example, when rearing up on the back wheel), the ABS system could take this as a dangerous situation.
In this case, 2 things may occur:
- the ABS system intervenes by releasing pressure from the calliper until the wheel turns again at the
same speed of the other wheel; it is not possible to brake for an instant.
- if the speed difference lasts long, the system may detect an error and deactivates the ABS system.
As a consequence, the system works as any regular braking system.
Riding with an active ABS system
•
During the vehicle start-up, after the in-
strument panel initial check, the ABS
warning light stops flashing when the
speed is under 5 km/h (3.1 mph).
If the ABS warning light remains on when the
vehicle is running, it means that a fault has
been detected and the ABS system has been
automatically deactivated.
IN CASE OF FAILURE OR WITH ABS DISCONNECTED,
THE VEHICLE OPERATES AS IF IT DID NOT HAVE THIS
SYSTEM.
Activating/deactivating the ABS system
It is only possible to access the menu, and espe-
cially the section "a-PRC CONFIGURATION" ,
which contains the item ABS when the vehicle is
stationary and by using the MODE selector.
