so your telling me that when my SSS light came on last year i should have replaced a wheel bearing at 30K? and i still should have replaced my wheel bearing when a simple scan of the Tech 2 Showed that it was the brake switch?????

The proper diagnosis via the GM Service manual for the SSS is > Step 1, connect Tech 2 scan tool

these cars dont eat wheel bearings, i have seen many Bonnevilles and been on the forms (3 Bonneville forums in fact) longer than you have and, its a myth of the "oh my wheel bearing is bad i have to replace the hub"

the Tech2, Snap on or a HP tuner will all pull codes needed to fix your SSS issue

The Service Stability System warning has been on for probably a year now. I miss ABS in the icy Detroit winter.

I realize a normal scanner will not pick up the body codes I need to see what the problem is, and that a Tech II scanner is required. I called my local garage, and he tells me he doesn't have a Tech II scanner, but he does have a Snap On scanner that should read the codes.

Is this true, or do I have to find someone with a Tech II scanner?

I have the FSM to interpret the codes. Can the problem (wheel sensors, steering wheel position sensor, accelerometer, or yaw sensors) be nailed down based on the codes, or is further diagnosis required?

By the way, this forum rocks, and the tech guys who take time to help us are awesome. Everything I fixed on my car was done after exhaustive reading of all the related threads in this forum, and I get my parts from Rock Auto at a discount thanks to this forum.

My snap-on scanner will read codes and data for abs. More then likely any shop that is worth their weight shouild be able to pull codes and read live data.

While a significant number of these failures tend to be related to the wheel speed sensors in the bearing/hub, there are a number of component malfunctions that can be related to your issue, including wheel sensors, steering wheel position sensor, accelerometer, or yaw sensors.

One member is suggesting you play the odds, and replace the parts that most likely are the source of the problem (wheel hub/bearing) as a means of avoiding unneccesary expense. The other member is telling you to get a Tech II scan to allow you to focus in on the issue before you start spending money. Aside from the fact they could have been a little more respectful toward each other in this discussion, both of their points have merit.

In my opininion, I would spend the $70 or $80 for a Tech II scan of your car to see what system is malfunctioning, as opposed to spending $200 (parts only) on wheel bearings only to find out they weren't the issue. If it turns out the wheel hub/bearings are the issue, you wasted $80. If it turns out something else is the issue, you saved $200.

By the way, a standard scanner that is capable of reading diagnostic trouble codes will not read these codes. You need a Tech II (dealer) or other such scanner that can read all systems on your vehicle.

If you get the codes and want help interpreting them, come back and see us. If you determine which component is the guilty party and want some help on how to replace it, come back and see us. In any case, please let us know how you make out.

Great. Now I only have about a dozen things to look for and install? Is there some test or method to detect the bad sensor? Is it possible that there was damage to the sensors when the brakes were done last time?

Dave. Take a deep breath. Have a beer. Relax a little. We are only telling you to do one thing. Get a tech II scan done on your car. It will point to the malfunctioning component.
