Service Suspension System message

[DenaliDrew]

HI all, this winter, I started seeing this message up in the high country of Colorado when it was fairly chilly. Now, it is appearing with regularity in the Denver area. The dealer said they couldn't find any codes. Which seems a bit like bs. Anyone experiencing this? This is on a 21 Yukon XL Denali Duramax but no air ride.

You said "THE" dealer. Go to a different dealer and make sure you ask for any current codes and history codes.

Or pick up a cheap ish OBDII reader on Amazon and pull the codes yourself. You can read them on your phone

take it back and have them or another dealer scan it while the message is active on the display, that's a body code, not a obd code, has to be read by a higher end tool that can read body codes, if the message is not present there may be nothing in the history either, just depends

Found this Info on the MFGR Communications section on the NHTSA web site (nhtsa.gov). Perhaps ask your dealer about 22-NA-222. Here is a link to the PDF shown: https://static.nhtsa.gov/odi/tsbs/2022/MC-10226120-0001.pdf

Thanks for the tips all. I did take it back last week with the message still on the screen and told them to figure it out. They have ordered some new module and are going to install it on Thursday. I will make sure to show them the technical bulletin as well. Hopefully everything will work out as I'm nearing 30k on Mt. Massive.

So, you did not already make them aware of the technical service bulletin?

 

[DenaliDrew]

Not previously, no, but I texted it to my service advisor.

Did they know about the technical service bulletin when they inspected and ordered a module? Are you on the hook for the parts and laboe?

 

[DenaliDrew]

They didn't mention it or really acknowledge it. It's in right now. I'm still under warranty, so no - hope not.
We had a snowstorm so I gave my wife the truck and had to push it back a few days.

So dealer swapped out a suspension module - took them a few days - message popped back later that same day I got it back. 6k left on warranty. Hopefully they'll be able to address it.

My 21 Tahoe had it at 30k
Dealer said front right wheele wire connected to a sensor relates to suspension is cut, they replaced that

Yea, my original dealer said they had swapped the module, but the message came back the same day I got it back. I took it to Alpine right down the road and it was fixed in 2 days and still fixed. Needless to say I have switched my preferred dealer.

I am having the same issue with “service suspension system” randomly popping up on my 2021 high country suburban. I visited the dealer today and they could not find any stored codes and told me I would have to come back with the suspension message active for them to troubleshoot the issue.

Could you share what parts the dealer repaired or possibly the repair description if it was a programming update from the service receipt?

I had the “Service Suspension” pop up yesterday. Popped up often but very intermittently. (I was surprised how many times the suspension is cycling during a drive!)

The day before I had popped the hood after pulling in the garage. Unfortunately, apparently the suspension was not done doing its whoop-de-dooos before popping the hood. When you pop the hood it “freezes” the suspension where it is, I guess confusing the module. Anyway, message kept popping up and I couldn’t even get to the control screen to change ride height.

30 second disconnect of the negative battery cable and it is back to working fine and like normal.

Thought this might help someone who has these random errors. Now instead of the “Italian tune up” we have to do the “whole car reboot”!

Thanks for the information. Hopefully this can help my dealer get the issue figured out for me. Interestingly enough if you Google the dtc C102E the attached video pops up that walks through diagnosing the issue and replacement of the sensor.

I had the same issue with my Tahoe. Took it to the dealer several times. It ended up being a faulty accelerometer. Replaced that and it’s been fine.

Do you know if your faulty sensor was driver side front or another wheel position?
