The service vehicle soon light has been coming on about once a week. It only stays on until I shut off the key. Then it won't come back on for a week or so. The maintainance is up on everything: brakes, transmission, belts, hoses, all fluids. The owners manual doesn't say anything about resetting the warnig and it doesn't show up on my CANOBD2 meter. What does this light mean and how do I make it stay off. Thanks, 831johnc
