  Problem: I have a LAUNCH X431 PRO3S+ Smartlink HD with an active software subscription. When I download and update the software, a message appears saying, "Insufficient storage space. Try again after cleaning." However, I checked the device and found that there is still plenty of available storage space. How can I continue updating the software? Solution: Open "ES File Explorer" on the X431 tool . If this app is not installed, you can download and install it yourself. X431 tools use the Android operating system, so additional apps can be installed. Tap "Internal Storage" and delete the "cnlaunch" folder. Then reopen the X-431 APP and try updating the software again. If the above method does not work, try going to "Settings" and performing a factory reset.

  LAUNCH X431 truck diagnostic tools can perform active tests on light-duty and heavy-duty trucks. For example, we can use "Engine State Monitor" to check the engine status when the accelerator pedal is pressed and released, making it easier to troubleshoot faults. In this article, we will use the LAUNCH X431 PAD V ELITE with the truck diagnostic kit to perform an "Engine State Monitor" test on a 2020 Foton Aumark . Operating Procedure: 1) Connect the X431 PAD to the vehicle’s OBD port and operate it on the X-431 APP. Click [Diagnose] -> [Foton] . Foton diagnostic software version V15.20 or higher is recommended. 2) After manually selecting the vehicle model, enter the vehicle system. In this example, we first manually select the vehicle model: Click [Select Vehicle Type] -> [Conventional Energy] -> [Light Truck Series] -> [Aumark] . Then enter the vehicle system: Click [Auto Scan] -> [ECM/ABS/SCR Scan] -> [All System...

  Problem: I purchased a new LAUNCH XPROG5 (G5) , but it cannot be used with the LAUNCH X431 PAD7 as an adapter; however, it connects normally when used as an ECU programmer via USB connected to my computer. I also have an older Xprog3 (G3) , which connects normally to the X431 PAD7 , indicating that the PAD7 itself is not faulty. Is the problem with the XPROG5 device? Solution: The XPROG5 is a new adapter released in 2026. If the X431 diagnostic software version is too low, it cannot be recognized. It is recommended to upgrade the X431 diagnostic software to the latest version and then connect the XPROG5 for diagnostics. If you cannot update, it is recommended to uninstall the current application and then download the new software via the "APP Init" program on your desktop. (The correct software version should be V8.0 or higher.) www.x431shop.eu
