I think it's in the owners manual, besides the mechanics at the dealership shoul know this info
What's happening is not normal. The TPMS light flashes and the DIC reads 'service TPMS'. It doesn't indicate in anyway that a tire is low or to check a tire, it reads service the 'system'. After a while the flashing light goes to steady on (for 10 to 20 minutes) and then goes off. While the light is on or flashing either the front left or rear left tire shows (-) on the DIC. I have manually checked the tires several times since this started and all are in nromal range.
