1. ALL SYSTEMS DIAGNOCTIC
Besides classical 4 systems, you are able to use this diagnostic tool to diagnose your car in complete systems, such as Fuel system, Emission system, Body, Powertrain and more. You are capable of reading hard DTCs when there are some issues with your vehicle's systems, clearing the trouble codes after handling malfunctions. To make sure all the systems performs well, you can view live data stream before driving out
Bi-Directional / Active test : This diagnostic tool supports active test (Bi-directional control) to request information or command a module to perform specific tests and functions. such as turning the fuel pump on and off, cycling the a/c clutch on and off.
Key FOB Programming: If you lost one key of car, launch x431 diagun iv can help you add a new one , but you need to get the PIN# of your car before you copy a key. NOTE: diagun iv can not reprogram.
