Ride height with AlfaOBD (air suspension)

[Gixxer750]

No error msg's! keep in mind though that i had a 1" drop ( lean) on the left side so my settings might not work for you as well. With my setting's I gained 2" front left, 1"front right and 1" on both rear

So day ! i grenaded EVERYTHING in my truck. still dont know how. must have tagged another option while scrolling. but the truck was set to made in Brazil. went from a 2015 to 2017. It also became a 4 door hatchback: just to name the funny ones. Damn the dealer ive been working this out myself. The ASCM as been a pain in the a**. wish i would have had this come up while searching for it.
I cleared all my no calibration issues, ride height, service ASCM, ABS, SRS, ESC, you know, everything. but the parameters i just cant get right are what im assuming are for alignment. CALIBRATION OFFSETS. and since it scrubbed everything when i F'd up, does any one have a reference for those settings. FUN. i already know more about this in 3 days than the dealers 30 year tech. lol

How did you manage to get all these new settings??
Just by changing the values for the ride height?

 

[Gixxer750]

I would love to know

 

[Gixxer750]

Im gonna fry my HIDs from all the ignition cycling lol. Headlights arr now deactivated on purpose. 2 days into it as i have time ive got all the errors gone except a check engine ambient air temp sensor stuck @ -40•F. Lol wtf

 

[Gixxer750]

Oh boy! Now im in business. Lots of work to do lol

Hey guys, I made a quick video for how to write suspension values with AlfaOBD on my 2016 Ram Rebel. Here it is:



Hope this helps everyone!

So it was one hell of an adventure, but trial and error is a great way (slow as hell) to learn alphas ins and outs. the truck is leveled/lifted....see picture for "normal" ride height, now with power everything tow mirrors AND 55w HIDs without this hot mess of crap. Good times!

 

[Frank Smith]

Sweet on the ride height. Have you found any way to change the auto lowering from 63mph? I would really like to see it lower automatically around 55 if possible.

Has anyone had any experience with verifying and or revising correct Calibrated ride Height Levels on the new 5th gen 2019+ Ram 1500. I have the Limited trim w/ 5 pos levels; Entry/Exit, Aero, Normal, OR1. OR2. Currently, have a 1/4 rake between drivers front vs pass and 1/2 rear left vs right. Not that big of deal but would like to see if I can't mitigate this using software before I install DIY links I made.

Looking into the calibrated ride height levels with alphaOBD, all levels are denoted as "0 mm". Does anyone know why there are no valid logged calibrated levels readings, and has anyone run into this issue? Has FCA changed the names on 5th generation for these true ride levels?

Looking back at previous pages/threads. it does appears that the ride heights are listed under as "front left Calibrated Heights" etc. For the 4th gen Rams.

 

[Gearheadx365]

Taking into consideration that per the manufacture doc, this is normal and is within tolerance. No rework required. I have included the correct worksheet to find the curb height for 5th gen 1500's provided by the dealer when I originally took the truck in to see if they could take care of the rake.

Does anyone know what the correct procedure and/or location (ground to bottom of fender or curb) to obtain the correct height values to input into alpha "Write Air Suspension levels". I am kinda confused on where they are getting these numbers? If we were to follow the curb height values, mine would be LF 8 / RF 8 / LR 7 / RR 6.5 mm. My issue is that other ppl have either provided photos and info in regards to their current/revised ride height levels from past research. For example; 68 / 53 / 53 / 72.

I have hit a wall and trying to find some clarification. Doc works through how to correctly obtain the curb height on your vehicle at all 4 corners. Keep in mind that this should be in metric and not standard and values should be used to input into scan. In this case alphaOBD in lieu of wiTech.

 

[Scott Nielsen]

Gearheadx, were you successful in changing the air ride height parameters with the AlphaOBD in a 5th gen? I'm trying to do the exact same and have been told it can't be done.

I recently have F'd up my settings in a similar fashion and hoping I can get that tech help out of your head. I went in with Alpha and started to address my lean issue but found that I could not adjust the values. In my great brilliance I ended up with my suspension bottomed out and unable to enter any values. when I attempt to write the values in the test it begins goes into failure but wont tell me why. It tells me there is a Fault of C156E to calibrate the ride height but I can't input values so how do I calibrate. So now my truck just takes up space till i figure this out. Any suggestions...

Been there. And broth I'm gonna be honest, I think luck got me out. I'll make sure to check in a couple times a day since I can right now. Let's figure this thing out. I have 1 hiccup, I have that progressive snapshot thing plugged into my truck and I can't take it out for a few months lol. The discount was worth it. So ill get that issue figured out. Until then start with using a scanner or obd wiz to clear any codes, clear it even if there aren't any. Then unplug the positive and negative battery terminals and zip tie them together over night to discharge all the modules capacitors etc. I'll get back to you with what I can remember shortly

The numbers you input are the distance between 1 and 2 in mm. Or did I misunderstand what you are trying to do

Please let me know I will have to drop off at the dealership Wednesday if I can't get er done!

Guys, after modifying your suspension height values , make sure you do a height sensor check. This will remove the ASCM from plant mode! Then clear your codes, make sure engine is not running for last part

What do you mean with plant mode?

 

[MrDazana]

I found out last week that when you go to write your height values, the ASCM goes into plant mode so the air suspension doesn't move while you are programing. It stays in this state until you run a height sensor check, and then it properly writes the values to the ASCM and resumes normal function. Its basically a quicker way to check your stuff right away instead of cycling the ignition and waiting for the system to balance it self out.

Interesting!

But if you skip that step, the system will take over the new values after a few ignition cycles etc..., right?
