Hey guys
i got a problem with my suspension on my 99 STS i don't know why the suspension is alway in hard mode i can feel every bump on the road and it seems that sometimes the rear shocks are pumped all the way up as much as they can i pulled up the codes and there is nothing in the RSS codes any help???????

 

i too have often thought the same with mine, and have written it off as the nature of the beast..... sometimes she'll run like on air, and others as you say every bump on the road.
have often wondered if and how it could be set for soft ride all the time......
anybody, any thoughts???

Trade me for my SLS suspension?..... JK! I wonder if you may have one or more sensor not working properly. I'm going to guess there are no codes?

 

Hmmm no codes in the RSS it dosen't show any massage like Service Suspension what kind of sensor can be bad???? or it may be the module???

 

I'm thinking the sensors that are on the struts could be the issue. If it was the module, then it would be more likely to display an error message on startup. There is a chance that maybe it saved a code at one time regarding the issue, but it's not consistent enough to see a regular CEL or error message. Do the climate control access to see the saved codes, and tell us if it did save anything. I keep seeing this same issue on a lot of forums, but not much answer....
