This 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 beeping tones. Data recovery completes within 10 seconds, indicated by the BUSY light. This W211/R230 ABS/SBC tool is designed for Mercedes vehicles with W211 and R230 chassis equipped with ABS systems. It addresses repair code C249F related to exceeded operation time of component A7/3 (hydraulic unit). This internal control unit fault typically requires module replacement, but this tool enables repair without replacing the entire control module. For safety, 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 pad, rotor, or fluid replacement due to high hydraulic pressure (up to 140 bar). Failure to deactivate may result in injury or system damage. This affordable, compact, and user-friendly tool serves as a practical alternative to STAR DIAGNOSIS testers for SBC system deactivation. It delivers reliable and safe performance for brake maintenance procedures.
