If the ATC indicator light remains on and the message "ALLARM ATC DISABLED" is
displayed on the dashboard, it means that a malfunction was detected and that the
ATC was automatically deactivated.
In this case carry out the following operations:
- stop the vehicle;
- Key OFF-ON;
- (IF APPLICABLE) start the engine;
- reactivate the system manually;
- ride the vehicle to a speed above 5 km/h (3.1 mph): the ATC warning light should
switch off;
- ATC system working correctly.
If the 'ATC system deactivated' indication persists:
NOTE
SHOULD THIS OCCUR, CONTACT AN Aprilia Approved Dealer.
THE ATC SYSTEM ACTS ON BOTH THE REAR WHEEL OBTAINING INFORMA-
TION FROM THE ROTATION/ LOCKING TONE WHEELS MOUNTED ON BOTH
WHEELS. ALWAYS CHECK THAT THE TONE WHEELS ARE CLEAN, AND REG-
ULARLY CHECK THAT THE GAP BETWEEN THE TONE WHEEL AND THE
SENSOR IS CONSTANT AROUND THE ENTIRE CIRCUMFERENCE OF THE
TONE WHEEL ITSELF. SHOULD THE WHEELS BE REMOVED AND REFITTED,
IT IS VERY IMPORTANT TO CHECK THAT THE DISTANCE BETWEEN TONE
WHEEL AND SENSOR IS THE ONE SPECIFIED. FOR CHECKING AND ADJUST-
MENT, CONTACT AN Authorised Aprilia Workshop.
