The Launch X431 MCU3 Adapter (Adapter Board Code: 307140131) is an essential expansion kit for the X-PROG 3 (GIII). It is specifically designed to handle Mercedes-Benz All Keys Lost (AKL) scenarios and advanced ECU/TCU reading and cloning.
Key Capabilities
Mercedes-Benz Support: Facilitates “All Keys Lost” programming and direct reading of ECU and TCU data to generate new keys.
ECU/TCU Operations: Supports advanced cloning and replacement for platforms including VW/Audi MQB, BMW continental MSV90, and specialized Mercedes systems like MED9.7 and VGS NAG2.
Bench Mode: Allows for reading and writing data directly from the control unit without full disassembly.
Broad Functionality: Also used for ADAS calibration, BMW E/F/G chassis gearbox operations, and Porsche Cayenne (2011–2017) key programming.
Compatibility and Requirements
Mandatory Hardware: This is an optional adapter and is not included with the standard X-PROG 3 kit. You must already own the X-PROG 3 (GIII) to use it.
Diagnostic Tablets: Works with the Launch X431 series, including X431 V, X431 PRO 5, X431 PAD V, and PAD VII.
Cloning Restriction: While basic reading works with most tablets, ECU/TCU cloning generally requires higher-end series like the PAD or IMMO tablet series (e.g., IMMO Pro, IMMO Elite).
