Update: Yesterday again for about the third or fourth time in the last 6 months randomly the air suspension warning came on at a start up. Not trailering or heavy load, just normal daily use. When this happened a regular restart would not clear the code but if the truck sits for at least 15 minutes between restarts the warning would go away with no other action taken. Yesterday was different, so I planned on getting to the dealership this morning at opening to have them scan the truck and was preparing to be without my truck again for another 5-10 days. Just for kicks I checked the fuse box for the loose fuses as the other posts on this thread recommend. Sure enough every single fuse in the box was loose, (not just air suspension). I pushed all of them back in to seat them properly and restarted the truck, but had no change… so I gave it one last try, I fully removed both f50 and f87 fuses for about 30 seconds, reseated them, restarted the truck, and then warning was gone and air suspension works fine. I put the suspension through multiple cycles with no issues. I will update if the warning comes back, but for those out there with this issue, try this procedure before wasting a trip to the dealership! Has to be a vibration / heating and contraction issue with these fuse boxes, because I have been in the fuse box before and they were not this loose from the factory. As for the ongoing issue, I know sometimes the modules just need a full reboot, like all tech, things lock up and need to be restarted to clear up the issue. Maybe there is an issue with my air suspension control module though and it will give up completely just out of warranty. (Will be my luck). But because every time I bring it to the dealer and tell them about this issue they say since the light is gone they can’t do anything for me because there are no stored codes.
