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.

Can i download OEM Pathfinder and SDD software from Topix instead of getting a new software HDD for vxdiag jlr doip scanners?
Yes, vxdiag vcx se jlr and jlr doip vci are compatible with both original SDD and Pathfinder software.
For SDD, you are required to install our SDD patch as well.
For Pathfinder, you can download it free to perform vehicle diagnosis function. Online programming requires a subscription.
VX Manager driver is also required. For SDD you will need to install JLR SDD driver, for Pathfinder, you have to install JLR DoIP driver.
