• Check the ABS motor for continuity. → [D-5]
2. Wire harness (ABS)
• Remove the ABS motor coupler and check for continuity between the black terminal of the ABS
motor coupler of the wire harness (ABS) and the negative battery terminal.
• Remove the ABS ECU coupler and check for continuity between the red/white terminal of the
ABS ECU coupler and the red/white terminal of the ABS motor coupler. → [D-1]
• Remove the ABS motor relay and check for continuity between the red/white terminal of the ABS
motor coupler of the wire harness (ABS) and the positive battery terminal.
3. ABS motor relay
• Check if the ABS motor relay operates correctly. → [D-2]
Malfunction code 35 (Disconnection is detected between the ABS ECU and solenoid system.
Downstream side of the solenoid relay.)
1. Disconnected coupler between the ABS ECU and HU solenoid
Connect the coupler securely until a "click" sound is heard.
2. Disconnection of the wire harness between the ABS ECU and HU solenoid
Check the conductivity of the wire harness and repair or replace the failure part.
1. ABS ECU
2. Red
3. Red
*Continuity between: "A"–"B", "A"–"C"
3. Battery terminal is disconnected.
4. When the items 1 to 3 are normal, replace the ABS ECU
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 state [when the
battery voltage is normal].)
Check the following:
1. Rotation of the front wheel
• Check that there is no brake disc drag on the front wheel and make sure it rotates smoothly.
• Check the front wheel axle for loose bearings and bends, and the brake disc for distortion.
2. Brake master cylinder and brake caliper
• Check that the brake fluid pressure is correctly transmitted to the brake caliper 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 fluid for water, for-
eign 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.
