So when I first purchased this yukon the ride was awful, did some reading and learned about the magenride. Purchased some cheap aftermarket replacements and installed them. Truck rode AMAZING for the test drive. The next day back to square one, no codes. Reached out to the company and had a new set of shocks sent. Replaced and the problem continued. No codes at first, now 6 months later it intermittently shows up as service suspension. No leaks, all connecters are intact and attached well. Air compressor airs up when first started or as needed with weight changes. Do I buy another set of OEM replacements? Or is this likely an ECM/fuse issue? When hooked up to diagnosis the computer reports being unable to connect module.
Im just wondering which way I should go wiht this at trying a repair. We want to keep the air in the back for towing purposes so we want to avoid a delete if possible.

Yep, I have been around and around with this before and it always ends with the OEM shocks to fix it. But lets try doing a scan to see if that shows us anything, here is a video to help.

There are three fuses you need to check as well, here is a video to help with that as well. I posted the fuses and there locations in the images below.
