Packing up the lx450, ready to roll out of town for the holidays, and my wife gets home with the sc430, and the check engine light is on ( car was just about to roll 50,000mi). No time to check it out, and still on the road. Is this related to the mileage (scheduled) or is it likely just a random problem? The car is an '02. any insight would be appreciated. Wc
