00 Cavalier Service vehicle light
 

Picked up a 2000 2.2, 5 speed cavalier to flip and I'm having an issue with a Service Vehicle light keeps coming on. ive searched my resources (Chilton Online Manual) and cannot find a good diagram to find a definitive answer to what trips this light... I've seen oil change interval but anyhow... the car will sit and run, no light for as long as you'd like with the handbrake up but about 3 seconds after releasing the brake the light comes on, no other light on the dash but this one and would like to get it off.. anyone have some insight on this or know of a diagram that shows what trips this light
