Turn the ignition switch to ON; the OBD tool light will illuminate, and the device will emit a beep tone, indicating proper operation. The tool allows restoration of the maintenance mode switch (25% - 50% - 75% - 100%) with a BUSY indicator light and audible tones. Data recovery completes within 10 seconds, indicated by the BUSY light. This tool is designed for W211 and R230 models equipped with ABS systems. Error Code C249F indicates that the operation time of component A7/3 (hydraulic unit) has been exceeded, signaling an internal control unit fault. This device enables repair without replacing the control module. For safety, deactivate the Sensotronic Brake Control (SBC) system before performing brake maintenance on W211 (E-Class) and R230 (SL-Class) models. System deactivation is required prior to brake pad, rotor, or fluid replacement due to high pressure (140 bars) in the system. Proper tools are essential to prevent injury and brake system damage. This tool offers a cost-effective, lightweight, safe, and easy-to-use alternative to the STAR DIAGNOSIS tester. It performs system deactivation efficiently and safely.
