APRILIA RS 660 2020 Manual page 88

When the vehicle is started, after the initial instrument panel check cycle, the ABS
warning lamp flashes until the vehicle reaches a speed of 3.1 mph (5 km/h), after which
it goes out.
If with the ABS activated (level 3, 2, 1) the ABS warning light turns on permanently,
or continues to flash even when exceeding 5km/h (3.1 mph), a failure has been de-
tected and the ABS has been deactivated.
In this case carry out the following operations:
- stop the vehicle;
- Key OFF-ON;
- ride the vehicle to a speed above 5 km/h (3.1 mph): the ABS warning light must be
turned off;
- the ABS system is working.
If the ABS disabled indication remains:
NOTE
SHOULD THIS OCCUR, CONTACT AN Aprilia Approved Dealer.
NOTE
IN THE EVENT OF A PROLONGED ROTATION OF THE REAR WHEEL WITH THE
FRONT ONE LOCKED (BURNOUT, MOTORCYCLE PLACED ON MIDDLE STAND,
ETC.) THE SYSTEM CAN BE AUTOMATICALLY DEACTIVATED WHEN THE ABS
and a-PRC INDICATOR LIGHT IS ON AND STEADY.
TO REACTIVATE, TURN THE IGNITION SWITCH OFF AND THEN ON AGAIN AND
SELECT THE REQUIRED SETTING.
