Users of LAUNCH X431 tablet devices may encounter some problems during use, such as being unable to access the engine system/unable to enter a certain function option, and being prompted with "Serial Number Access Is Prohibited"/ "Function not available" when using the diagnostic function. In these cases, you can upload diagnostic feedback to facilitate LAUNCH engineers to analyze the cause.
This article will introduce how to submit diagnostic feedback on the LAUNCH X431 IMMO device. Other models of X431 diagnostic tablets can also refer to this step for operation.
First, on the main interface of the X-431 APP, we can see the "Feedback" option (if you can't see this option, please upgrade the software), click to enter Feedback.
Select the vehicle brand that needs feedback.
Select the diagnostic log (the diagnostic log is generally dated for easy confirmation).
Fill in your contact information (Phone Number/Email)
Submission results
After submission, if you want to check whether the engineer responds, you can find your diagnostic feedback submission record in the History option.
