After replacing the brake booster with master cylinder assembly or brake booster with accumulator pump assembly, if air bleeding is not performed and the vehicle is driven at a certain speed or more, the No. 2 skid control ECU (brake actuator assembly) judges that air bleeding has not been completed and illuminates the MIL and stores this DTC.
Furthermore, this DTC is not cleared until air bleeding has been completed.
