Do any members know of a Coder reader for Dodge Ram air suspension system?

Is theGet yourself AlfaOBD, you can check codes for more than the AP codes which is all most readers do. You can also test function of the air suspension along with other systems on the vehicle.
Best to use the the OBDLink MX or MX+ Bluetooth reader and an android phone or tablet.
If the truck is '18 or newer you'll also need a security gateway module bypass.
Well, technically……..the rear/four-corner air suspension is supposed to be a sealed system that uses nitrogen but, they made the system to where it can purge some of that nitrogen and supposedly draw in small amounts of outside air as well.I'm shocked to read that Ram does not include an inline air drier ( or auto air tank purge valve) for air suspension systems, no wonder so many people problems in colder weather... IMHO only an idiot would install air anything without an inline air drier or air tank without an auto purge valve...
Even in a closed system you will collect condensation from temp changes...Well, technically……..the rear/four-corner air suspension is supposed to be a sealed system that uses nitrogen but, they made the system to where it can purge some of that nitrogen and supposedly draw in small amounts of outside air as well.
Egh, I beg to differ. I believe that’s why it’s a closed system- well, supposed to be, anyways, with nitrogen. It’s purely a design flaw in my opinion making it to where it can purge the nitrogen out for whatever reason and pull in air from the outside. That’s where the condensation comes from because if it truly was a closed system, there’d be no moisture to get in there to begin with.Even in a closed system you will collect condensation from temp changes...
Do you know if the software comes with this OBD2? I went on Goggle app and as far as I can tell it is about $50 bucks?Is the
OBDLink MX+ OBD2 Bluetooth Scanner for iPhone, Android, and Windows the right one, I goggled AlfaOBD and there were many that turned up?
Thank you.The alphaobd software does not come with the OBD2 scanner. It would be an app in your phone store that costs about $50. Well worth it if you plan on doing anything to your vehicle
