Hey guys.Have a 96 850.Had someone I know hook a scan tool up to it.The only code that came up was telling me to replace the pnp switch on the side of the transmission.Reason I had it checked was that there was an idiot light on almost all of the time on my dash cluster.Had the switch replaced (used a factory volvo part). Seemed to do the trick. Now when I start the car the orange service light comes on in the lower right corner of the cluster.It does not stay lit though,it goes off after 20 seconds or so.Can anyone tell me how to fix that? Do i have to clear or reset something so the light stops coming on every time I start the car?

Thanks
