You need an OBDII tool that resets Volvo service light codes. See this service light reset forum thread for more. They run about $100 to 200 — or — take it in to the dealer or independent Volvo mechanic and have them do it. Call to see if they charge for this first. Note: I’ve read reports of people having success with having the local Shucks/Pep Boys/Checker auto parts store do it.
