2015 Ram 1500 Air Suspension Update

[rocketman1083]

Took my truck in to my my seats fixed today and they told me there was a flash update applied for the air suspension on my truck. This must be a relatively new update as the truck was in for service about 2 months ago. Anyone able to lookup or find what this update may be involving and what it is supposed to address?

Thanks

Thank you so much. The dealer wasn't able to tell me what the flash update actually fixed with the ASCM. Thank you for the clarification, I really appreciate it.

Hey guys, looking for some help with my 2015 1500 Longhorn. I’ve been having issues with my air suspension. My suspension still “works” but is not level. The drivers side sits about 1.25 inches lower on the front and about 2 inches lower on the rear drivers side. No matter what ride night I’m at it is always lower on the drivers side. It looks like when older trucks would brake a leaf spring. If anyone can help or give tips that would be awesome! I’m at about 70k miles of that helps at all. Thank you!!
