Hello, new to this forum and looking for some help or insight into a particular problem.
The front of my rebel is completely down on the stops ( so much that the caster/camber is way out)
I replaced fuses and relays
If I jumper out the relay the compressor does come on
Holding the buttons for 40 seconds does nothing, not even the chime but will throw new codes up saying buttons are stuck.
Tried every option form the screen and get no reaction
When hooked to the alfa obd ( also tried the icon t7) almost every test function doesn't work ( cannot complete test, ecu encountered a problem )
The few tests that will work don't actually do anything even though it's says complete. Fill , deflate, test say complete but the compressor never cycles
Check air ride sensors test says test complete but nothing happens.
I bled the nitrogen out manually through the right service port on the manifold and refilled with nitrogen ( rear bags stayed inflated when the charge was removed from the tank)
With almost every function from in the truck and from the scanners not doing anything im starting to believe the problem is the ascm.
Just looking for some advice before purchasing a ascm.
I am new to the air suspension but not to rams.
Any help would be greatly appreciated!

Im aware of the air delete and will probably go that route in the future, im just looking to get a fix for now. My shop has my 71 super bee , 71 charger, a ton of parts and I have a entire sheet metal shop in my barn. Im currently working on the rebel in a buddies heated barn and kinda need the truck sooner then later. I can find the ascm for 500 or less, especially if I just get a used one to get me buy until late spring. I was just curious if someone had any insight to the problem. If alfaobd can't preform any of the tests with most tests saying " ecu encountered a problem " it leads me to think it would be the ascm.

Not worth the headache. Been there. Def a GREAT opportunity to swap it out. You don't even need that much. Loaded struts up front. Springs, isolators and struts for the rear. I avoided the 'kits' and went with what was available at the time: Bilstein 5100's and B12 springs in the rear. Rancho 9000's up front. Was my first time diving into the Ram1500's suspension and took 4 hours. Was very straight forward.
