Rear Wheel Rotation Sensor Wiring Inspection (Service Code b 45)

If the wiring is open, replace or repair the harness (see KIBS System Circuit in the Brakes chapter).

If the wiring is good, go to next step.

Perform the Pre-Diagnosis Inspection 1 and 2 (see Inquiries to Rider in the Brakes chapter).

If this service code appears even if all checks are ended, replace the rear wheel rotation sensor (see Rear Wheel Rotation Sensor Removal in the Brakes chapter).

Still, when it is not good, replace the KIBS hydraulic unit.

If the service code does not appear, the KIBS system normal (temporary failure).

Rear Wheel Rotation Sensor Signal Abnormal (Service Code b 44)

Measure the air gap between the rear wheel rotation sensor and sensor rotor. Thickness Gauge [A] Air Gap Standard: 0.4 1.6 mm (0.02 0.06 in.) If the measurement is not the standard, ch ...

Power Supply Voltage Inspection (Low-Voltage) (Service Code b 52)

Check the battery condition (see Charging Condition Inspection in the Electrical System chapter). If the battery is good condition, perform the Pre-Diagnosis Inspection 1 and 2 (see Inquiries ...

Oxygen Sensor Installation (Equipped Models)
NOTICE Never drop the oxygen sensor [A] especially on a hard surface. Such a shock to the unit can damage it. Do not touch the sensing part [B] to prevent oil contact. Oil contamination from hands can reduce sensor performance. Tighten: Torque - Oxygen Sensor: 25 N·m (2.5 kgf·m, 18 ...

Rear Caliper Holder Shaft Wear
The caliper body must slide smoothly on the caliper holder shafts [A]. If the body does not slide smoothly, one pad will wear more than the other, pad wear will increase, and constant drag on the disc will raise brake and brake fluid temperature. Check to see that the caliper holder shafts ar ...

Intake Air Pressure Sensor #2 Input Voltage Inspection
NOTE Be sure the battery is fully charged. Turn the ignition switch to OFF. Remove the air cleaner housing (see Air Cleaner Housing Removal in the Fuel System (DFI) chapter). Disconnect the intake air pressure sensor #2 connector and connect the measuring adapter [A] between these con ...
