SPEED LIMITED TO 88 M/H

apparently it can happen on the gmt900's also per a couple youtube video's, also happens on the camaro's and caddy cts, sierra/silverado pickups

it is, either it needs to be recalibrated or there is a active code, this type of code will not cause a check engine light, but may come up as a message in the dic, such as "service suspension system" or if you replaced the shocks with aftermarket and did not use a delete kit or the delete kit has failed.
again this has come up a number of times and it is directly related to the suspension, it could always be something else no one has reported otherwise in years

Thanks Doubeleive,
You are correct this problem has started after replacing the shocks, which is more likely it.

you can use resistors which should resolve the problem

Did you replace the Magneride shocks with GM OEM Magneride (or aftermarket active shocks) or aftermarket passive shocks?

Do you have a quality bi-directional scanner? That would help pinpoint the source of the issue.

Were replaced with aftermarket shock, but believe it or not, the problem has disappeared by its self without reprogramming. Now the vehicle drives smoothly and to normal speed.

if it comes back then check those resistors, unless they are built in then it could be a faulty shock (intermittent)

How do the clowns that offer all the money saving products of deleting z95 or z55 manage to leave out all these known issues when they’re advertised?

Almost a third of the posts in some of these forums is a long series of questions that ultimately comes back to …. “yea, I did add the uguha duguh MagRide delete kit, what does that have to do with it?’
