    Crashy susupension

    I've noticed recently my suspension becoming more and more crashy. Going over small bumps or broken Tarmac bangs through the full truck. And driving if to hits a dip it's not very stiff, it rocks side to side like a boat.
    There is no service message and the compressor is new.
    It's just too bouncy but when it hits a bump it's like there is no suspension.

    Sounds like the suspension system is in passive mode

    If not getting any codes then I would suspect bad shocks

    Mine is doing that as well. Shocks have been ruled out as I put newer ones on and still suffer the same issue.

    This spring I plan on rebuilding the entire suspension. I've been under her a few times and it looks like the bushings have had it, I'm thinking the bad drivability in my case is from the suspension shifting due to worn rubber. I've also questioned the torsion bars on mine as even with new shocks it feels too spongy. I have 90K miles on my truck, what I consider being end of life for suspension components based on previous experience with my GMs over the years.

    I had the harness fail connecting into my SCM (suspension computer). It results in the auto-ride system disengaging w/o an error code to indicate the failure. The truck drove like all 4 shocks were blown, I spent a ton of money chasing shocks, sensors and the compressor when really the harness connector just needed to be cut off and reconnected back to the harness. Without going to the dealer, where the Tech 2 tool was unable to communicate with the SCM, I was just not able to diagnose this by myself. My advise, spent the $1xx and have the dealer do the diagnosis, then come back here and figure out the cheapest solution.
