Air suspension height question!

[jeffauclair]

Hello all

I had my ASCM replaced on warranty last week. When I took my truck back, I notice right away that something was different. See pictures attached of my truck on NORMAL height. Keep in mind that I do not have the OFFROAD package and I still have 5 height available (exit aero normal of1 of2). Is it me or my truck is way higher than what it supposed to be? I would like someone to compare my height on the picture with their truck height to see if my dealer did update the wrong parameters.

It definitely looks like it’s in one of the off-road modes...looks like off road 2

The things is that I can still achieve 2 higher mode. Dealer must have screwed something. Is there any protections mode on air bag to avoid going to high?

The heights should've been calibrated with the ASCM replacement.

I know, but my truck is higher now than before the replacement. Either my previous height wasn’t right, or this one is. I just wish I had a picture or height number to compare with someone else truck

Here is OR2 in essentially the same truck (no ORG for me though). Yours does not look as high IMO, my guess is your new module is working appropriately and perhaps the earlier one was off calibration when it went out. More I look at it and line things up as best as possible side by side, my guess is yours is 1-2 than what my normal would be... but you are an ORG. I now have 35's otherwise I would go and take a pic of my wheel wells. Best thing to do is measure dead center of your wheels from ground to wheel well. My front was 37" when stock before I added daystar/35s.

Hey thanks for sharing. Actually, I DONT have the ORG. That is why I'm confused. You might be right when you say that my previous ASCM might has been out of spec and because I took the truck like that, I was thinking this was the correct height. I will verify if I got 37'' to the ground/wheel well center. Thanks again for taking the time to share pictures!

I just lowered to AERO, and I have 37 flush on AERO mode. 38 ish'' on Normal. I have an appointment tomorow at dealer. Hope they can modify the ASCM. I just don't get how the procedure works when they replace the ASCM to come the the height I have right now.

Yeah, that seems a bit tall then. With my 35” tires and day star spacers I’m currently at 39.5” up front and 40” in the back.

Dealer did reprogram the ASCM today. Now I am at:
37 Front Passenger
36 5/8 Front Driver
39 Rear Passenger
38 7/8 Rear Driver

I assume the driver side being lower is normal ? I am also 1/8 of gaz tank level.

No I just lifted levelled my rebel and your way off I’m the same driver and passenger sides for reference for you. They can do better getting it level.
