1. Purchase an OBD II code reader machine from an auto parts store.
2. Or the easier, cheaper way: take your vehicle to Aamco Transmissions or Midas shop and they will check it for free!
If the Volvo is 1995 or newer, they can pull the codes very easily.
If it's 1994 or older, they can pull the codes but it takes more labor.
Whichever shop you go to may charge you if your Volvo is 1994 or older. But you can always try to negotiate the price down and see if they'll go for it.
The Aamco I took my '94 to wanted $98. I said forget it, but since they took so long with my car they through in the test free.
