ECU Coding - Help the newly replaced ECU/module to work properly

Why does the car not work properly after replacing the ECU/module?

When the ECU/module is damaged, replacing it with a new ECU/module is necessary. After processing the replacement, you must follow the manufacturer's strict procedures for matching, learning, coding, and even programming it to get the car to run properly. Otherwise, the car could not start, or some parts will not work. Launch scanner X431 V+ 4.0 can help you do that.

LAUNCH X431 V+ PRO 4.0 Support Advanced ECU Coding Functions (Online Coding, Offline Coding, Flash Hide Functions)


  • Code Adaptive Data: Every automobile actuator has a record code in ECU, which is the basis for automobile computer to mobilize their work. LAUNCH X431 V+ escaner automotriz professional has the ECU coding function to recognize new actuators after you change the fault actuators or parts.
  • Recognize Replaced Modules: ECU coding enables multiple car systems to recognize each other and then the actuators can start to work.
  • Flash Hidden Functions: This feature is used to activate hidden features that most car manufacturers include that are not available to the average car owner. Examples include corrective consumption calculation, seat belt warning, auto start/stop, hidden menus, daytime running lights, cruise control, automatic locking and unlocking of the central locking, comfort windshield washer, welcome lights, etc. To enable most of these functions, it is enough to activate them (in the car's "brain"), while for some others it is necessary to install additional missing modules in the car.


For example:

- The new Ford Focus can be upgraded to a tire pressure monitoring function by flushing the ECU. This feature is especially important for those who like to drive long distances, significantly improving the safety of the car;

- Mercedes-Benz E-Series can change the much-criticized air conditioning mode by brushing the ECU to improve passenger comfort;

- VW Passat can be swiped to "modify home/leave time", "selective door locking and other functions";

It is important to note that, due to hardware and other reasons, such as the Audi Q5, if you want to brush the "home/away function", you must have the automatic headlights function.

ECU Coding Compatibility

Online Coding: BMW, VW, Audi, Skoda, SEAT, Porsche, etc.

Offline Programming (Variant Coding): BENZ, Ford, Mazda, Vauxhall, Opel, etc.

Flash Hidden Functions: Benz, BMW, VW, Audi, Skoda, SEAT, Porsche, Jeep, Dodge, Chrysler, Toyota, Honda, etc.
