06 DTS. Service Brake System light comes on every week or two. Resets by cycling the ignition switch.

New pads on the front a month ago, rear have 1/8 inch left.

How do you find the cause?

The first thing I would do is check the brake fluid level... assuming you have not already did that.

The next thing I would do is... Assuming you have OnStar.... When the light comes on again, push the OnStar button and they can tell you the exact code that is set.

Post the code here and we will try to help.

Thanks Jim, I didn't know OnStar could do that. Or I kind of did, but didn't think about using them for that.

Ozlander,
I checked the 2006 DTS manual and see that SERVICE BRAKE SYSTEM will display if your vehicle is low on brake fluid (p.3-84). Have you checked into this possibility already?

The message hasn't returned. The brake fluid level is at the seam which is 3/8" above the 'MIN' mark.
