This post is available with the advantages of Multi-system Data Stream Reading and how to use this function on Launch X431 PAD9 LINK, X431 PAD V, or X431 PAD VII.
What is the highlight of Multi-system Data Stream Reading?
X431 PAD9 LINK (PAD IX) supports similar functions as PAD V and PAD VII.
The main differences are that PAD IX comes with the new SmartLink C 3.0 VCI which takes more enhanced WIFI communication and more secure connection, it has the newest operating system, the biggest operation screen, the largest memory and storage, and the highest camera pixel, and it supports multi-system data stream reading now.

X431 PAD V and PAD VII will support the multi-system data stream reading function as well soon.
A data stream means the real-time data parameters of sensors, switches, and actuators linked to the vehicle’s electronic control unit.
For technicians, reading the data stream is critical when we scan fault codes using the diagnostic tool.
Sometimes the combination of one or several fault codes alone isn’t enough to fully identify the cause of the problem. This is where the data stream comes into play.
At this point, by analyzing the parameters and changes within the data stream.
We can accurately pinpoint the root cause of the vehicle issues.
However, for some complex problems, it might be necessary to view the data stream from multiple systems or ECUs at the same time.
The new function- Multi-system data stream reading can help you easily tackle these challenges. It allows you to freely combine and view the data stream from multiple systems at once. Making it faster to locate the source of the problem.
How to use Multi-system Data Stream Reading?
Connect the Launch SmartLink C VCI to the vehicle’s OBD port
Connect SmartLink C and X431 PAD series tablet via WiFi
Once it’s successfully connected, select “Intelligent Diagnose” or “Local Diagnose” to enter into the topology mapping.
For example: Intelligent Diagnose
It will connect the VCI in WiFi mode, read VIN, and decode VIN automatically.
If your vehicle model supports, you will see an additional “Multiple System Data Stream” menu in the left hand menu bar.
Select this menu to enter the Multi-system Data Stream Reading page
On this page, you will find 3 columns: System, Data Stream, and Combine.
You can select and combine the data streams from different systems.
You will see options for “Whole Vehicle Core Data Stream” and “Historical Self-selection”.
By selecting Whole Vehicle Core Data Stream”, you can view all the core data stream options for the specific vehicle mode.
Once you’ve selected the desired core data stream, press “OK” button.
Then you will see the display interface for the selected data stream from the multiple systems.
To better monitor the data stream dynamically, click the icon on the right side to view the graphical data stream, also click the arrow icon on the right.
You can select up to 4 data streams once and view all the live data streams at the same time.
Which vehicle can support multi-system data stream reading?
Currently, only Nissan, BMW, Audi, VW, and Mazda support. More vehicle models such as Toyota, Ford, Chrysler, and Fiat will support this function soon.
With the multi-system data stream reading, X431 PAD IX, PAD V Elite, and PAD VII Elite can help technicians locate the vehicle faults more quickly, significantly improving diagnostic efficiency.
