: Finding or Viewing Diagnostic Codes in 2008 STS

10-17-10, 02:30 PM
Hello all,
My mother just purchased a used 2008 STS. She did own an 01 SLS, and I knew how to pull up the codes on the dash for that car - I simply held info down and info reset to bring up the menu.
Can codes be displayed on the newer cars? What is the secret button combination?

The secret is,,,, they screwed us :(

No more DIC codes, you'll have to invest in some sort of code reader. Be sure it does Can-Bus, I have both a cheap $30 one and a good scanner that pulls ALL the cars codes for like $400.

Also, if she's a subscriber to OnStar, and the light comes on, you can simply call them and they'll tell you what the code is.
