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 ...

Other materials:

Shift Fork/Gear Groove Wear Inspection
Measure the thickness of the shift fork ears [A], and measure the width [B] of the gear grooves. If the thickness of a shift fork ear is less than the service limit, the shift fork must be replaced. Shift Fork Ear Thickness Standard: 5.7 6.0 mm (0.224 0.236 in.) Service Limit: 5.6 mm ...
