LAUNCH X-431 Diagun V Functions

Read ECU Version & ECU Coding:

  • Because every automobile part (actuator) has a record code in ECU, which is the basis for automobile computer to mobilize their work. When you change a new part, the code changes. You need to use Diagun V to make a code so that the ECU of the car can recognize your new part.

Bi-Directional Actuation Test :

  • LAUNCH X431 diagun v Scan Tool gives you what snap-on scanner offers.Also known as component activation, Diagun V can be used to turn on and off actuators to determine whether there are problems with sensors and actuator.

Matching + Adaptation+ Initialization:

  • Also known as adaptive function, it can adjust the data of the actuator so that the data of the replaced actuator can be accepted and recorded by ECU.For example, when you clean the carbon deposit on the throttle, there is engine idle jitter. That's because your throttle angle change data is not recognized by ECU, resulting in inconsistent data, and the engine can not work accurately. You can make a match with Diagun V to synchronize ECU data with throttle data after cleaning.
