Fault
code No.
Front wheel will not recover from the
locking tendency even though the sig-
AbS_41 nal is continuously transmitted from the
ABS ECU to release the hydraulic
pressure.
Rear wheel will not recover from the
locking tendency even though the sig-
AbS_42 nal is continuously transmitted from the
ABS ECU to release the hydraulic
pressure.
Incorrect signal from the front wheel
AbS_43
sensor is detected.
Incorrect signal from the rear wheel
AbS_44
sensor is detected.
AbS_51
Power voltage is too high.
AbS_52
AbS_53 Power voltage is too low.
AbS_54 Power voltage is too low.
Hydraulic unit sensor power monitor
AbS_56
circuit is abnormal.
AbS_63 Front wheel sensor power is abnormal.
AbS_64 Rear wheel sensor power is abnormal.
* A fault code is indicated if the rear wheel rotates for longer than about 20 seconds (fault code No.
AbS_11) or for longer than about 2 seconds (fault code No. AbS_25) with the front wheel stopped
(e.g., when the vehicle is on the centerstand).
TIP
Fault codes Nos. AbS_15 (front wheel) and AbS_16 (rear wheel) are indicated if a defective connection
is detected in the front or rear wheel sensor when the vehicle is not being ridden.
