• Mileage alteration: The OBDLink MX+ is a diagnostic tool and does not support altering vehicle mileage (odometer).
• Multilanguage support: The device itself is not multilanguage; its functionality depends on the language support of the connected application. The official OBDLink app is primarily in English.
• Compatibilité avec des véhicules/applications spécifiques : While compatible with all OBD-II compliant vehicles, specific advanced functions (like coding injectors, changing tire size, or proxy alignment) depend on the capabilities of the third-party app used (e.g., AlfaOBD, BimmerCode, FORScan) and the vehicle's ECU. Refer to the third-party app's documentation for detailed compatibility.
• J1939 protocol: The OBDLink MX+ does not explicitly support J1939 for heavy-duty vehicles like Cummins. It supports standard OBD-II protocols including ISO 15765-4, ISO 14230-4, ISO 9141-2, SAE J1850 VPW/PWM, SAE J2411 SW-CAN (GM), and MS-CAN (Ford).
