Check under your hood for a grey box with a bunch of wires bundled together on the drivers side near the brake fluid resevor and there is a metal bracket that bolts right on to the engine.. The wire ran to the engine is a ground and you need to make sure that it has a good and clean connection and make sure that the bolt is tightly screwed on... When you hit a bump or something that causes the connection to move or loosen, the light will come on....

I hope this helps....

That has happened to me before. I parked the truck, turned off the engine, waited for about 5-10 and restarted. As long as the reduced speed indicator and/or the check engine light don't remain on you are good to go...hope this helps
