VXDIAG VCX SE Not Connect to Land Rover CAN BUS?

Problem:

I was programming a Land rover Discovery 3 with vxdiag vcx se jlr SDD and noticed I was not reading any units that are on high speed can bus.  Opened the vcx and found this U20 chip is broken.

No CAN BUS communication with this chip blown.

Solution:

You can search ebay for main board U20 EEPROM, then changed the interface.

It will all be ok.
