FEATURES
1-10
The front and rear sensor rotors each have 92 magnetic poles (46 pairs) and are installed close to the
wheel sensors. As the sensor rotor rotates, the Hall element in the Hall IC installed in the wheel sensor
generates pulses. The pulse frequency, which is proportional to the magnetic flux density, is converted
into a wave in the Hall IC so that it can be output.
The ABS ECU calculates the wheel rotation speed by detecting the pulse frequency.
ABS warning light
The ABS warning light “1” comes on to warn the rider if a malfunction in the ABS occurs.
When the main switch is turned to “ON”, the ABS warning light comes on for 2 seconds, then goes off,
so that the rider can check if the ABS warning light is disconnected and check if the ABS is operating
properly.
NOTICE
ECA2S31063
If the rear wheel is raced with the vehicle on a suitable stand, the ABS warning light may flash
or come on. If this occurs, turn the main switch to “OFF”, then back to “ON”. The ABS operation
is normal if the ABS warning light comes on for 2 seconds, then goes off.
