Problem: Mercedes-Benz Sensotronic Brake Control (SBC) warning light illuminates. If the SBC is not working, limited brake pressure is applied to the front brakes, decreasing braking power and increasing the stopping distance. The SBC hydraulic unit has a specific service life programmed into the control module.
Solution: Mercedes-Benz brake system inspection and diagnosis. Follow the Mercedes-Benz-recommended Sensotronic Brake Control (SBC) service procedure for proper maintenance of the SBC.
