Service Ride Control

[Marshall2002]

Hi all. I recently changed front shocks on my 02’ Denali. A few days later, I get a Service Ride Control message. The shocks I replaced were the factory shocks, not air shocks and did not have a integrated ride height sensor. There was some weird cap connection on the top post of the shocks which I reconnected on the new ones although I’m not sure the purpose. The rear compressor is working. I’m not sure if the new shock are related but is seems awfully coincidental. Any help would be appreciated.

I’m not 100% on your model but what did you replace them with? The front and rear shocks are separate so either one can throw that light on.

I replaced the fronts with the suggested replacements from 1A Auto. They looked exactly like the ones removed.

The plug at the top is for electronic dampening. Check those connections.

If they didn't have the ride height sensor then how were they factory replacements? Don't all NBS Denali's have them or are they just on the upper control arms? Curious bc I'm dealing with suspension issues as well.

My 2016 Yukon is riding as if the shocks are pumped up all the time. Very stiff ride. Any solutions out there?

Any dash lights on? How many miles on your shocks/struts? Just the rear is rough? Tires over inflated?

Side detection issue on dash. Automatic seat position system won’t respond to buttons on door panel. Those issues my be unrelated…
Shocks are stiff in front and back. Any way to reset this system?

your system used magnaride front shocks with air on the back. Make sure the when you plugged in the top of the shock you locked the connector in. That connector sends an electrical signal to the shock to the metalized oil in the shock. That controls the dampening of the shock. The connector has half turn lock collar and make sure the connection is clean and locked in place. You should not be able to pull the connector off if its attached correctly. A lot of people damage it trying to remove it incorrectly. Also there is an unmarked fuse in the fuse box you can remove, disconnect the battery negative then reattach the negative and leave the fuse out and it will disable the ride control. You may have to clear the fault first before doing that. Mind you the fuse trick works on MY2000 with just magnaride but i think the ECU reconizes this up till 2006. The shocks will then be de-energized but will ride like an old lincoln. Check all your ride height sensors and makes sure they aren't damaged or disconnected.
