2023 Yukon Duramax "Service Suspension Soon" Message.

[EGTroup]

Recently started getting "Service Suspension Soon". Took to Carl Black GMC in Orlando. They pulled the attached problems with the CAN Bus.

In shop for diagnostics. Seems as though the problem is with the CAN Bus communications between various components and not necessarily the air suspension at all.

We will see what they find and cost to correct.

After two days, tech cannot identify the cause. All systems seem to be working fine but these error messages keep popping up. Dealer consulting with GM for what to do next.
