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.

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).

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 ...

System Components
1. KIBS ECU With input from the front and rear wheel sensors and front caliper hydraulic pressure, the KIBS ECU analyzes various conditions on the motorcycle, and with additional information from the FI ECU (engine speed, throttle position, gear position, and clutch actuation) precisely control ...

Fuel Type
Use clean, fresh unleaded gasoline with a minimum Antiknock Index of 90. The Antiknock Index is posted on service station pumps. The octane rating of a gasoline is a measure of its resistance to detonation or “knocking.” The Antiknock Index is an average of the Research Octane Number (R ...

Clutch Plate Warp Inspection
Place each friction plate or steel plate on a surface plate and measure the gap between the surface plate [A] and each friction plate or steel plate [B] with a thickness gauge [C]. The gap is the amount of friction or steel plate warp. If any plate is warped over the service limit, repla ...
