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).
