PIAGGIO MP3 300 hpe 2020 Manual page 34

Condition: key "ON" (regardless of whether the engine is running or not) and ASR
system NOT voluntarily deactivated by the user
•
The steady on ASR indicator light indicates that wheel radius learning has
never been performed. Calibrate; if the ASR light remains steady on, there
is an ASR system failure: in this case you must contact an Authorised Serv-
ice Centre for the diagnosis and the reactivation of the system.
•
The steady on ASR indicator light and the steady on engine fault indicator
light indicate that the wheel radius learning procedure has been performed
but with a negative result. Perform a new calibration; if the ASR light remains
steady on, there is an ASR system failure: in this case you must contact an
Authorised Service Centre for the diagnosis and the reactivation of the
system.
ASR indicator light flashing
Condition: vehicle stationary and engine running
•
A frequency of 0.5 flashes per second (0.5 Hz), indicates that learning is in
progress. The indicator light starts flashing at 0.5 Hz when the button se-
quence required to start the learning procedure is pressed.
Condition: vehicle stationary, key to "ON" and engine switched off
•
A frequency of 1 flash per second (1 Hz) occurs when, with the key to "ON"
and the engine switched off, the ABS control unit reads that the learning has
already been carried out successfully; the ASR indicator light will switch off
as soon as the engine is started and the ABS has ascertained the congruence
between the speeds of the two wheels (it is necessary to exceed a minimum
speed so that the ABS can carry out this task, in order to switch off the ASR
indicator light).
Condition: vehicle in motion
•
A frequency of 5 flashes per second (5 Hz) when the vehicle is in motion,
indicates that the ASR system is operational and activated by a low grip con-
dition, with a reduction in engine power; ride with extreme care, as the grip
limit has been exceeded; restore the vehicle to safe conditions by gently re-
ducing the speed.
