This may sound weird but on the 2000 Silverado, there was a loose leaf addendum to the owner's manual that said to reset the service engine illuminator, turn the ignition key to access, not run, just access and then depress the accelerator either three or five times. My manual is at home and I can't remember which it was but after doing that it should reset. The service engine light is a device that tells you when you reach a set number of miles you need to take your vehicle to a Chevy service center for about a week and then they'll bill you about $2000 to change your oil, and other fluids, belts and hoses. I passed on my service and did it myself for about $200 one Satyrday afternoon.
