Volvo Repair - "Service" Light on Dashboard


Expert: Roger Patricio - 5/5/2009

Question
Roger:
You were such a big help to me with my recent headlight wiper arm problem (all fixed now, thanks again) that I am now coming to you with another question, this time relating to the dashboard "Service" light on my '93 Volvo 850GLT.  I believe that the "Check Engine" light on newer vehicles comes on when an onboard computer detects an actual problem, but apparently my light is less sophisticated - according to my Owners Manual, it simply comes on (for a brief period) each time the engine is started after various mileages, driving times or calendar intervals are reached and will continue to do so until a service technician resets it (hopefully after performing some appropriate service).  The most recent service on my car was the 120,000 mile one (the most major level, to be performed at 30,000 mile intervals), but it was done a tiny bit early with 119,976 miles actually showing on the odometer.  Shortly after getting the car back from the shop I noticed the Service light coming on as described above and I'm guessing that the technician never reset my system so that it was triggered when I actually hit the 120,000 mile mark.  Does that sound like a reasonable explanation to you and, if so, can I do my own resetting without special tools or knowledge or must I make another visit to the shop?  Of course, I suppose I could just continue to ignore the light, but it sometimes makes my passengers nervous!

Answer
Ed, you can do this.  Follow these steps.  Go to the 2 little blocks by the washer resevoir.  REmove the left cover and put the pin in position 7.  Turn key to pos 2.  Push the little button 4 times, wait for the light to go off, then push button 1 time, wait till the light goes off, press button 5 times, wait for light to go off and finally hit the button 1 time.  The light should flash rapidly and now the light is reset.  Take care.  Roger
