John..thanks for the info on the DIC, I never knew that it would display something like that. As for the spare, yes I did. In fact, I took the car to a Tire Kingdom so that they can properly measure and inflate (or deflate) all the tires (including spare) to the factory settings but still the light is on.
As I mentioned before, I tried to reset the light but its not blinking 3 times and therefore, not resetting itself.
