Replaced Rear Shocks with OEM and Getting "Service Suspension" a day later

[jeeplaw]

At a bit of a loss here, in none of my research did it indicate that replacing OEM for OEM on my 2015 Denali with Magenride would result in the Service Suspension message. I checked all the connectors, the air lines are attached..what am i missing? I read somewhere on Facebook about doing some sort of a recalibration? I haven't replaced my worn out front shocks yet (I've got a pair of Arnotts waiting to go on), would the difference in height front to back cause the message?

Welcome to the Forum from NH.

Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.

I hope that you will become a participating member in the Forum's discussions.

Pics of the truck, please.

Are your rear shocks inflating properly (4-6 second run time by the compressor) when you start the truck, after it has been sitting overnight?

Also, check the electrical connector on top of the frame near the shock's top bolt. That connection occasionally comes undone, when replacing the rear shocks. It has happened to a number of us on the Forum.

Do you have, or have access to, a quality bi-directional scanner? It would most likely point you to the source of your issue.

The plug near the top of the shock is likely unplugged. It happened to me when I did the shocks on my avalanche

They are plug and play and you shouldn’t get any codes. The calibration resets the level but it won’t throw an error.


Worse case is if you can’t find the problem get a scanner and get the code. It will tell you what the issue is, probably a loose connector somewhere.

Also a compresssor or air suspension issue will show a “leveling system error” so it’s not likely that.
