in the memory of the ABS ECU, but the ABS has not malfunctioned. Delete the malfunction codes.
• The rear wheel was rotated with the vehicle on the centerstand.
• The rear wheel raced.
• The vehicle was ridden on the rear wheel with the front wheel elevated.
2. The front wheel sensor is not properly installed.
• Check that the front wheel sensor is properly installed in the housing.
Refer to “MAINTENANCE OF THE FRONT WHEEL SENSOR AND SENSOR ROTOR” on page
4-20 and “INSTALLING THE FRONT WHEEL (FRONT BRAKE DISCS)” on page 4-22.
• Check if there is looseness between the housing and the wheel.
Refer to “MAINTENANCE OF THE FRONT WHEEL SENSOR AND SENSOR ROTOR” on page
4-20 and “INSTALLING THE FRONT WHEEL (FRONT BRAKE DISCS)” on page 4-22.
3. Front wheel sensor circuit is short-circuited.
• Front wheel sensor or lead is short-circuited.
Refer to “MAINTENANCE OF THE FRONT WHEEL SENSOR AND SENSOR ROTOR” on page
4-20 and “INSTALLING THE FRONT WHEEL (FRONT BRAKE DISCS)” on page 4-22.
• ABS wire harness and wire harness are short-circuited.
Refer to “CIRCUIT DIAGRAM (1/2) (FJR13A)” on page 8-119, “CIRCUIT DIAGRAM (2/2) (FJR13A)”
on page 8-121, “CIRCUIT DIAGRAM (1/2) (FJR13AE)” on page 8-123, and “CIRCUIT DIAGRAM
(2/2) (FJR13AE)” on page 8-125.
Malfunction code 41 (Front wheel will not recover from the locking tendency even though the
signal is continuously transmitted from the ABS ECU to release the hydraulic pressure (when
the battery voltage is normal).)
1. Rotation of wheel
• Check that there is no brake disc drag on the front wheel and make sure that it rotates smoothly.
• Check the front wheel axle for loose bearings and bends, and the brake discs for distortion.
2. Brake master cylinder and brake caliper
• Check that the brake fluid pressure is correctly transmitted to the brake calipers when the brake lever
is operated and that the pressure decreases when the lever is released.
3. Brake fluid
• Visually check the brake fluid in the brake master cylinder reservoir and the brake fluid reservoir for
water, foreign materials, solidification, and contamination.
• Check for air in the brake hose lines.
4. Brake hose lines
