This tool allows for service and maintenance of the SBC system on compatible vehicles without requiring replacement of the control module. For Mercedes-Benz models equipped with the Sensotronic Brake Control (SBC) system, including W211 (E-Class) and R230 (SL-Class), safety precautions require the SBC system to be deactivated before performing brake system maintenance. Deactivation must be performed prior to changing brake pads, discs, or fluid, as the system operates under high pressure (up to 140 bar). Proper tools are required to ensure technician safety and prevent damage to the brake system. This SBC tool provides a cost-effective, lightweight, safe, and easy-to-use alternative for deactivating and reactivating the SBC system, compatible with W211 and R230 models equipped with SBC. It performs system deactivation and activation reliably and safely. After maintenance is completed, the SBC system can be reactivated and system pressure restored.
