BITS002 Bench Adapter for BitBox – Automatic Power & Boot Control (J2534 / Scanmatik Compatible)
The BITS002 Bench Adapter is a specialized breakout interface designed for on-the-bench connection and flashing of modern automotive electronic control units (ECUs). Engineered specifically to work in tandem with the BitBox flasher software and J2534 Pass-Thru devices, it provides automated power switching and boot-pin line management directly through your hardware interface.
Equipped with a standard OBD-II female connector, the BITS002 seamlessly couples with high-performance J2534 interfaces such as Scanmatik SM2, SM2 PRO, and SM3, eliminating manual power toggling and external bench box complications.
It is purpose-built to operate with the updated BitBox module: Bosch MG1/MD1 Gen2 BSL/BENCH, unlocking reliable reading, writing, and bench servicing for post-06.2020 locked Bosch MG1 and MD1 control units.
Key Features & Benefits
- Automated Power & Boot Switching: Full automatic control of ECU power supply (+12V, GND) and Boot lines managed directly by the BitBox software protocol via J2534 lines.
- Direct J2534 Integration: Features a robust OBD-II female port for instant plug-and-play connection to J2534 interfaces (Scanmatik SM2 / SM2 PRO / SM3).
