An OBD2 tool with a 16-pin connector compatible with the vehicle’s OBD-II port. Turn the ignition switch to ON — the device power indicator lights up, followed by two beeps, confirming proper operation. To reset maintenance mode, adjust the switch setting (25%, 50%, 75%, or 100%). The BUSY indicator will illuminate and emit beeping tones; data recovery completes within 10 seconds while the BUSY light remains on. Compatible with Mercedes-Benz W211 and R230 models equipped with ABS systems. Diagnostic code C249F indicates “Operation time of component A7/3 exceeded (hydraulic unit).” This suggests an internal control unit fault. Using this tool, the issue can be resolved without replacing the entire control module. Safety note: Before performing any brake system service on W211 (E-Class) or R230 (SL-Class) vehicles, the Sensotronic Brake Control (SBC) system must be deactivated using a STAR diagnostic tester. Deactivation is mandatory before servicing brake components (e.g., pads, discs, fluid), as the system operates under high pressure (~140 bar). Proper tools and training are essential to prevent injury or system damage. This lightweight, portable, and cost-effective tool serves as a practical alternative to STAR-DIAGNOSIS for SBC deactivation and related functions. It delivers reliable and safe performance.
