Front Wheel Rotation Sensor Wiring Inspection (Service Code b 43)

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 front wheel rotation sensor (see Front 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).
