Greetings all.
I bought a '23 Denali 1500 and installed a rough country 3.5 lift. Love the truck. I took it to the dealer for the free oil change. The rep told me it had a bunch of error codes (attached pic), and he needs to get the truck back in.
It seemed weird to me, because the truck runs and drives perfect, and it's never had a check engine light. Only thing I can think is the lift, which involved disconnecting and re-connecting various wires. But everything is connected properly right now.
Has anyone seen these error codes?
Is this something I should be concerned about?
Thank you.
