How to Solve SD Connect C4 WIS VIN not Found, Datacard not Display


If the MB SD Connect C4 WIS VIN not Found, Datacard not Display how to solve it ? Please do not worry , Here is all my experience with MB SD Connect C4 WIS & EPC.

I have installed EPC 02/2016 and WIS 04/2016 in ewa-net.

However got into some troubles with WIS datacard option that is grey.

What so Lucky I managed to solve it!



EPC works fine but in WIS when it give VIN, i have this error message:

vehicle identification number not found.
datacard cannot be displayed.


I opened with my Notepad the wis_cfg.xml file from the EWA-NET Folder\Config &

searched the word: “datacardurl” replaces the lan ip address with “localhost” in the

2x points that i watched:

<PARAMETER name=”gateway”>EWA-net/ewa-net</PARAMETER>
<PARAMETER name=”datacardUrl”>http://PC.localdomain:9000/EPC-net/datacardapi</PARAMETER>
<!– URL of datacard service for Snap On’s datacard view: –>
<PARAMETER name=”datacard_V2_Url”>http://PC.localdomain:9000/EPC-net/dcapi</PARAMETER>

and i changed it to:
<PARAMETER name=”gateway”>EWA-net/ewa-net</PARAMETER>
<PARAMETER name=”datacardUrl”>localhost:9000/EPC-net/datacardapi</PARAMETER>
<!– URL of datacard service for Snap On’s datacard view: –>
<PARAMETER name=”datacard_V2_Url”>localhost:9000/EPC-net/dcapi</PARAMETER>

The wrong part is http://.

I remove it

Save the .xml file and Reboot the PC!

All works fine now!!!!

I think I should buy items from a more professional seller like My brother bought MB SD C4 Plus Original EVG7 Tablet PC instalaltion well there and never got into troubles like me. His WIS and EPC with SDconnect also works well.
