Tire pressure monitor light comes on when starting car in the morning. Light goes out after driving a short distance. I have checked pressure before driving and they are correct pressures. Followed owners manual to synchronizing sensors to correct location on vehicle. Upon starting procedure horn beeps twice and indicator light goes out. Light is supposed to flash during synchronizing procedure. Finished process, but do not know if it will solve problem with warning light coming on with correct tire pressure. Did get all proper audible beeps during synchronizing process. Is there a problem with my tire pressure monitoring system?

Follow up - I did try disconnecting the battery for 15 min. to see if that would reset the light and still does not come on and flash during synchronizing process.
