    2022 RAM 2500 - Help Calibrating Rear Air Suspension?

    So I installed my unlock cable on my truck because I'm about to tune it.

    My truck is a 2022 RAM 2500 with rear air.

    I have the Jscan app and was using it to recalibrate my speedo for the 40s.

    While using it, I decided to see what I could do with the rear air suspension.

    I accidentally clicked on calibrate rear air.

    When I realized that I clicked on it, I backed out.

    After this, I get the "service air suspension" light on. No matter what I do, the code C156E-00 will not clear.

    I even downloaded and paid $50 for the AlfaOBD app and tried calibrating it, but no matter what values are put in, it will not clear.

    I can't get my truck in the dealer for two weeks.

    Any help?

    I have been reading up on AlfaOBD, and it's recommended that you download the factory settings in case you have to revert after a mistake or something.

    Is this something you might have done with the Jscan?

    Also, if you know anyone with a 5th Gen 2500 with airbags, maybe get their factory settings to mirror?

    I don't have airbags on my 21', or I'd try to get them for you.

    I looked on other forums, and your situation sounds like a PIA.

    230 to 240 manually entering the values is worth a try to see if the light will come off.

    I'm trying to dig for you.

    That made the light for away with 230 values, but the rear is sitting quite high now.

    Maybe I will try dialing the numbers down a little at a time and try again.

    Thank you for the help.

    I appreciate it.

    I'll check back and let you know the results.

    To clarify for anyone else who has done the same thing.

    I could not get the Jscan app to clear the light; I had to use AlfaOBD.

    I've tried everything; the only number that will shut the light off is 230 or 220, but the rear is jacked way up.

    I'm going to the dealer Friday.
