Advanced ECU Coding

Same as other LAUNCH X431 High-end OE-level scan tool , LAUNCH X431 PAD III has the capability of ECU coding to change preprogrammed options in the software, helping you customize your car faster as needed.

You can match, relearn, and code the newly installed ECU module after making repairs or replacements,such as setting alarms, doors locking, etc.
You can change the market-specific settings to activate higher-level car functions and disable unneeded features, breaking limitations.
Access the ECU to make full use of the hidden features or disable the car’s annoying functions, like activating the auto side mirrors folding function, disabling the automatic engine Start-Stop function, etc.

Provide excellent solutions for issues of drivability, power loss, fuel efficiency, etc. to improve the car’s performance.
Reprogram the adaptive data for certain components after repairs or replacements.

Powerful Online ECU Programming
Programming new ECUs: Replace new ECU(Determine if programming or coding is required based on fault code prompts). It can read and back up the original ECU data of the vehicle. (Note: The newly purchased spare part numbers need to be equal to the original ones.)

Reprogramming second-hand ECUs: Clear second-hand ECU data for reprogramming(if the second-hand has the anti-theft data, it needs to be used with LAUNCH X-PROG3 to clear anti-theft data first, and then match it with the original anti-theft data before reprogramming.).

Update the ECU: Some of the ECU has BUGs so it will cause some faults that are difficult to repair. ( For BMW 2889 DME in take valve, carbon deposition, and some of F serious machine oil lamps can't be zero.)

Fixing lost data of ECU: When the software in the ECU corrupts the program due to battery or grounding issues(the Hardware is normal), re-programming can rectify it back to normal operation.

What different is Online Programming and Offline Programming ?
Online Programming

It 's download the original data from automaker service directly , it is ensures the correctness and latest version of the data you get , Improves the success rate of programming .

Offline Programming

It 's for you had the data , just write it to you ecu directly( if you do not have the data , you can not do programming function ).
Support Car Models:
for Mercedes-Benz, for BMW, for BMW Brilliance, for MINI, for Volkswagen, for Audi, for Jaguar, for Land Rover, for Porsche, for Shanghai Volkswagen, for FAW-Volkswagen

If you are in North America, only the following car models are supported:
for Mercedes, for BMW

All ECU programming functions are not supported in Portugal and Spain.

ECU Coding changes preprogrammed options which depend on the type and number of electronic features already built in. Thus, ECU coding is not universally compatible and varies for different vehicles.
