This is my first Chevy and got an 8 inch lift and 37 inch tires the first time I put it in four-wheel-drive to drive home from work the next day I got up and it said service four-wheel-drive system. What does that mean?

Great video, where could I find that plug, my dog pulled the wires off of it, chasing a cat under my truck, the wires and plug still good just Ned the right order in the plug to check if I can clear the code

My Autel scanner also does the same thing. Not fully clearing fault codes using the "clear all codes" function. Yes, it only takes a few more seconds but it's annoying as hell. They need to fix that glitch! Anyways, Good find and repair.

[@PhillipBailey]

Thanks for the comment. I don't think it's the scan tool at fault. I've noticed even using OEM scanners the same issues. Also on some ABS systems you can clear codes but they don't actually clear until the system performs a self test which might require a key cycle or wheel speed input.

Can you recommend someone with such skills in Los Angeles area?

[@PhillipBailey]

No sorry I can't. Best to join a forum for your truck and ask the group who they would recommend.
