ECU Coding

The LAUNCH X431 PRO3S+ supports advanced ECU coding and bi-directional control to quickly identify replaced modules, ensure smooth communication, activate hidden features, and adjust vehicle settings by commanding specific tests or functions (e.g., toggling actuators to test sensors).

ECU coding re-flashes vehicle control modules and reprograms adaptive data after component repairs or replacements.

• Online Coding: Access OEM server data for high-level repairs.
• Offline Coding: Read code from original module and write to new module.
• After replacing control units, actuators, or key parts, coding ensures the ECU recognizes and stores the new components. Applicable to engine, fuel, injector, transmission, ABS, airbag, and other systems. Always record the Original module’s information before coding.
• ECU coding enables cross-system recognition so actuators function correctly.
• It unlocks hidden vehicle features—such as customizing interior lighting, enabling cornering headlights with fog lights, or disabling door-lock buzz sounds.
