ABS (ANTI-LOCK BRAKE SYSTEM)
8-152
Malfunction code 42 (Rear 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 rear wheel and make sure that it rotates smoothly.
• Check for brake disc distortion.
2. Brake master cylinder and brake caliper
• Check that the brake fluid pressure is correctly transmitted to the brake caliper when the brake pedal
is operated and that the pressure decreases when the pedal is released.
3. Brake fluid
• Visually check the brake fluid in the brake fluid reservoir for water, foreign materials, solidification,
and contamination.
• Check for air in the brake hose lines.
4. Brake hose lines
• Check the brake hose lines for kinks and deterioration (particularly between the hydraulic unit and
the rear brake caliper).
WARNING
EW3P61005
Only use genuine Yamaha parts. Using other brake pipes, hoses and union bolts may close the
brake hose lines.
• Check that the connections of the brake hose lines from the brake master cylinder to the hydraulic
unit and from the hydraulic unit to the proportioning valve are correct.
WARNING
EW3P61007
The rear brake will not function properly if the connections are reversed.
• Brake hose “1” inlet: from the rear brake master cylinder to the hydraulic unit
• Brake hose “2” outlet: from the hydraulic unit to the proportioning valve
NOTE:
• If the rear brake hose inlet and outlet connections are reversed on the hydraulic unit, the brake pedal
will be pressed down to its full-stroke position without responding, and then it will be pushed back
slowly without pulsating when the final check on page “[D-3] FINAL CHECK” on page 8-157 is per-
formed.
• If the front and rear brake hose connections are reversed on the hydraulic unit, the pulsating action in
the brake lever and brake pedal will be performed in the reverse order when the final check on page
“[D-3] FINAL CHECK” on page 8-157 is performed.
• If the brake hoses (to the proportioning valve and the metering valve) are switched during assembly,
the brakes will continue to operate as normal. However, the reduction of the hydraulic pressure for the
rear brake and part of the right front brake will be reversed during the ABS operation when the final
check on page “[D-3] FINAL CHECK” on page 8-157 is performed.
5. Hydraulic unit solenoid coupler terminals
• Check if the front brake, rear brake, and unified brake system solenoid coupler terminals (hydraulic
unit and ABS wire harness) are connected correctly.
