Dreaded Service Air Suspension message.. 2019 GC Trailhawk
Hello all,
Hoping someone here can lend some insight or is even a Jeep tech. Over the last couple months I have sporadically gotten the service air suspension immediately message on the dashboard while driving. I would get worried. I’d have to go turn the car off get back in and the air suspension seemed to work fine. Now mind you I am the original owner and have raised to vehicle to OR2 maybe 50 times? That could even be an exaggeration. I love in the northeast so it would be only for snow and a handful of times I brought it on the beach. It has never been rock crawling or “true” off roading. This winter was harsh. Lots of snow and brutally cold which I suspect is what pushed this along. Anyway enough of my banter.
I consider myself a fairly capable DIYer and have worked on cars my whole life so I bought a wireless OBDII dongle and the 12x8 security cable. I downloaded Jscan and began my diagnostics. The compressor appears to be fine. The car will decide when it wants the suspension to work and will raise/lower upon command. Other times it won’t and gives me the dashboard message. This also tells me (maybe) that the valve block is fine. I checked all the wheel sensors. They’re attached and facing the right directions, and honestly look incredibly clean for a jeep with 81k on it. I still have an original battery. It reads approx. 13.3V when idling. I suspect this could be the culprit, but I am going to attach a bunch of diagnostic screen shots and hope that maybe the best jeep tech in this forum sees them and can tell me what’s wrong.
I tried several deep dives with AI and haven’t had much luck. I did also attempt to calibrate, but I’m not sure if I was measuring from the wrong places or what so I had to set the ECU back to suspension from the factory settings
Thanks in advance for any help. If there is any other info that you need from me that would help please let me know.
