Launch X431 X-431 PRO3(V+5.0) Diagnostic Tool Functions: 

[All Systems Diagnosis]

Enables you to scan full control units for a number of cars such as Engine, ABS, SAS, Transmission, Fuel system, Emission system, Body, and so on. Deep Diagnosis Your Vehicles: access to ALL vehicle systems and subsystems, to perform a comprehensive scanning on ECUs.

[ECU CODING]

The Coding function is used to re-flash the vehicle control modules, it allows you to reprogram adaptive data for certain components after making repairs or replacements, providing ways for the issues of Drivability, Fuel Efficiency, Power Loss, Fault Codes, Durability of Mechanical Parts.

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 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.
 

[BI-DIRECTIONAL CONTROL/ ACTIVE TEST]

• This diagnostic tool LAUNCH X431 V+ supports active test (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 X-431 PRO3(V+5.0) also have the ability to actuate relays, injectors, coils, or perform system tests, etc.
