Bi-directional Control + Active Test + ECU Coding + All Systems Diagnostics

>> Want a Bi-directional scan tool?

This diagnostic tool LAUNCH X431 V+ supports active tests (Bi-directional control) to request information or command a module to perform specific tests and functions. For instance, in the case of OBD II generic information Mode 1, you can initiate a request for information from the powertrain control module, and the PCM responds by sending the information back to the scan tool for display. This LAUNCH X431 V+ also has the ability to actuate relays, injectors, coils, or perform system tests, etc.


Because every automobile actuator has a record code in ECU, which is the basis for automobile computer to mobilize their work. LAUNCH X431 V+ is equipped with an advanced ECU coding function for addressing the following issues:

1. After you change the bad actuators or certain parts, you need to use this function to make a new code and recognize the new actuators.

2. By changing the code with the ECU coding, it’s easy to improve vehicle performance or stimulate high-end functions for the car.

3. ECU coding enables multiple car systems to recognize each other and then the actuators can start to work.
