Problem:
When i connect the VXDIAG VCX FD GM scanner to a 2021 Yukon, gds2 cannot communicate with the vehicle. I connected to a 2015 Yukon which is not can fd and gds2 is able to communicate with the vehicle. The device is running the latest firmware. Any solution?
Solution:
2021 GMC Yukon Denali should be CAN FD protocol. vcx se/vcx nano would not connect to it. If VCX FD has no commucaiton, VXDIAG engineer released a patch solution at present.
They are working on new GDS2 driver for VCX FD exclusively, the problem will be fixed soon.
Current solution:
Contact www.vxdiagshop.com to download GDS2 CAN FD Patch file (file name: BVTX-VCI-PDU.dll)
Copy and replace the patch file in C:\Program Files (x86)\GM MDI Software\Products\MDI 2\Dynamic Link Libraries folder.
NOTE:
The patch is for VCX FD scanner only. It is not compatible with VCX SE series.
