W211/R230 ABS/SBC Tool for Mercedes An OBD tool with a 16PIN connector that plugs into the vehicle's OBD-II communications port. Turn the ignition switch to ON; the OBD tool light will illuminate, and the device will emit a beep tone, indicating the device is functioning properly. The tool allows restoration of the maintenance mode switch (adjustable at 25%, 50%, 75%, or 100%). During this process, the BUSY indicator light will flash, and the device will emit beep tones. Data recovery completes within 10 seconds, indicated by the BUSY light turning off. This W211/R230 ABS/SBC tool is designed for Mercedes models W211 and R230 equipped with ABS systems. It addresses repair code C249F, which indicates excessive operation time of component A7/3 (hydraulic unit). This fault typically suggests an internal control unit issue. Using this tool enables repair without replacing the entire control module. For safety, it is recommended to deactivate the Sensotronic Brake Control (SBC) system before performing brake service on W211 (E-Class) and R230 (SL-Class) models. Deactivation is essential prior to brake pad, rotor, or fluid replacement, as the system operates under high pressure (up to 140 bars). Proper tools are required to prevent personal injury or damage to the brake system. This tool provides a cost-effective, lightweight, safe, and easy-to-use alternative to STAR DIAGNOSIS testers for SBC system deactivation and maintenance mode reset. It performs essential functions efficiently and safely.
