service light on 1996 volvo station wagon

Hi,

My service light on my 96 850 volvo wagon keps coming on when I start
the car then goes off after about 2-3 minutes. A friend of mine just
bought the tool for reading the codes and we hooked it up but it says
there are no codes to read and the car is fine. I think I will not
pass the MD emmissions test with the service light on after starting
the car (maybe I can leave the car running when going to the test :>)

Any ideas on what is going on and how I might be able to reset it. It
does not look like I can do it with the tool so I think I am out of
luck.

Thanks for any help
Jim

 

That is your service light A.K.A. (oil change light). It is not indicating a
fault, it is just indicating a service interval.

The check engine light would indicate a fault.

Now the bad on your 96 the service light is reset with a computer,
most code readers will not do it. One that will reset the light can be found
at http://www.obd-2.com/ this is what I use on my 96.

 

Or you can have whatever required service is due done at the dealer. Dealer
prices are usually reasonable as long as they don't talk you into a lot of
extras.

Thanks for your reply. I plan on doing all my own service (oil
changes, etc...) myself so I guess I will need to live with the service
light coming on every time I start the car. I will check with my
friend about his tool he has but I think it just checks the fault codes
and can reset them.
