Turn the ignition switch to ON; the OBD for TOOL light will illuminate and the device will emit two beeps, indicating the device is functioning properly. This tool allows restoration of the maintenance mode switch (25% - 50% - 75% - 100%) with a BUSY indicator light and audible beeps. Data recovery completes within 10 seconds while the BUSY indicator is active. This W211/R230 ABS/Tool is designed for Mercedes models W211 and R230 equipped with ABS systems. It addresses repair code C249F, indicating the operation time of component A7/3 (hydraulic unit) has been exceeded. This fault typically indicates an internal control unit issue. The tool enables repair without replacing the control module. For safety, prior to performing brake system maintenance on W211 (E-Class) and R230 (SL-Class) models, the Sensotronic Brake Control (SBC) system must be deactivated. Deactivation is required before any brake service such as pad, rotor, or fluid replacement, as the system operates under high pressure (up to 140 bars). Proper tools are essential to prevent personal injury and brake system damage. This compact, lightweight, and easy-to-use tool provides a reliable alternative to the STAR DIAGNOSIS tester for deactivating the SBC system. It performs the required functions efficiently and safely.
