This modified ELM327 USB diagnostic cable features a built-in switch, designed specifically to be compatible with Ford, Mazda, Lincoln, and Mercury vehicles. It supports accessing modules that are invisible to regular OBD2 scanners by switching between HS-CAN and MS-CAN protocols. Key Features: MS-CAN & HS-CAN Support: Unlike standard ELM327 adapters, this device allows you to toggle between HS-CAN (Pins 6 and 14) and MS-CAN (Pins 3 and 11). This is essential for accessing manufacturer-specific modules on supported vehicles. Advanced Diagnostics: Capable of displaying trouble codes, PIDs, running tests, and service procedures that are not displayed by standard OBD2 scanners. Powerful Functions: Supports resetting fault codes, changing car configuration data (CCF), running tests, and programming certain models when used with appropriate software. Vehicle Compatibility: Brand Support: Designed to be compatible with Ford, Mazda, Lincoln, and Mercury equipped with an OBDII connector. Hidden Function Support: specifically compatible with Focus (2006-2016), compatible with Kuga (2013-2015), and other models supported by FORScan. (Note: Many models approximately since 2003/2004 are equipped with MS CAN bus, which requires this modified adapter). Software & System Compatibility: Supported Software: Works with FORScan, FoCCCus, FF2, and ELMconfig (Note: For ELMconfig, baud rate support is 34800). Operating Systems: Compatible with Windows XP, 7, 8, 10, and 11. (Windows 7 is recommended for best stability). Important Usage Notes: Driver Installation: Please ensure the USB driver (CH340 or PL2303, depending on batch) is correctly installed on your computer before use. No CD Included: Drivers and software must be obtained separately. Internet Connection: It is recommended to disconnect from the internet while using diagnostic software to ensure stability. Package Includes: 1 x ELM327 USB Diagnostic Cable with Switch
