08 Tahoe LTZ service suspension system

Hey everyone on my 08 LTZ Tahoe it’s coming up with service suspension system on the dic, the compressor seems to be working correctly, I unplugged and replugged all the electrical connections at the shocks and compressor to see if it had a bad connection. It seems to be doing it intermittently as sometimes it’s on and sometimes it’s off it started doing this a couple days ago.

Yes one is for the right rear

you need a tech2 to see what the code is, regular scanners wont read it. you could take it by the dealer and ask it they would scan it for you, some will do it free some wont.

and the last time mine started doing the exact same thing it was a loose connector on the front right shock, the front shocks have a connector with a metal clip double check those because I thought mine was on but it was actually loose and I could pull it off by hand, had to reconnect it properly and put the metal clip back on, it was causing a intermittent connection.

Mine flashed off and on when one of my tpms went bad. I’d clear it and the dic light came back and the service light would go on and off. Didn’t make sense to me. Not sure if that’s your case but worth a shot.
