ECU Coding

used to re-flash the vehicle control modules, it allows you to reprogram adaptive data for certain components after making repairs or replacements.You can use our x431 v pro to stimulate all the possibilities of the vehicles

After we replace control units, bad actuators, or certain parts we need to do the coding to make the replaced parts being stored and recognized by the ECU. Almost all systems that include engine, fuel, injector, gear shift, ABS, airbag system, and so on can be coded with this scanner. Before the coding, please read and record the original module’s information.
