Prior to creating a new thread, I searched on this topic to no avail. I have a 2006 DTS Performance with approximately 49,500 miles. About a week ago, the "Service Suspension " message appeared on the dash. A day or two before that I had the rear two tires changed, just supplying some background data. I was hoping someone can point me in the correct direction in regards to trouble shooting and eventually resolving issue. Thanks for any help in advance.

Sounds like the guys who put the tires on messed up the Mag ride. Probably pulled a connector loose.Crawl under there and check the connectors at the bottom of the shocks. And of course there are sensors which sense wheel movement and they are electrically connected to the computer so look for wires hanging down near the wheels.
Other than That, I don't know what to say.

I would be inclined to take the car back to the tire store and put it up on their lift to do the inspection.

What Southern said...I would do that.

I noticed by your mileage, that you are maybe still under warranty.
Don't let it get over 50,000 before taking it to the dealer and getting it on record that you have an issue.

Thanks for your assistance guys. Just went under the car, and everything seems to be fine. Any other suggestions before I go to the dealer?

If everything seems to be plugged in and nothing is loose...I would get it to the dealer while it is still under warranty.

Depending on what it may need...Those parts can be very expensive.

Did you get your issue resolved? if so what was it? Could you have gone another 10 K on Originals or did you feel like it was too rough and noisy? What tires did you get? from where? how much? and DO you like them?

I have that same message on my car. 2001 DTS. It's been doing that since 2008. However, the Tire Sensor came off and and that's when it started. Check your tire moniters. That's what's probably causing the message.

I also have the same message on my 06 Performance. The rear shocks were leaking a lot so I replaced them and I still have the message and its limited to 80. Where are these wheel movement sensors and what else can cause the service suspension message? The front struts look good. Sway bar links and all the other components are good too.

You need to have the codes read. The auto parts store readers won't read suspension codes. It takes a high-end Snap On or equivalent or a Tech 2. The codes will tell where the issue is that's setting the light. On my Suburban with Autoride, it was a left rear position sensor that failed.

 

[Scottyj13]

These are the codes last time I had them read. Ive googled them of course and my question is what devices are these codes related to on the DTS? All I can find is general code descriptions.

P0689 ECM/PCM Power Relay Sense Circ Low
P0600 Serial Comms Link Error
P0289 Injector Circ Hi-Cyl10
U0214 Lost Comm With Remote Func Actuation
B1517 Battery Voltage Below Threshold
C0899 Device 1 Voltage Low
B1325 Device Power 1 Circuit Malfunction
