This morning my TPMS indicator came on. At first I though because of the crazy weather it was like last time, no issue. I would just fill up the tires and all would be good. Filled up the tires and the light was still on. I checked the manual. The light actually blinks prior to turning steady at startup. So somthing in the TPMS is malfunctioning.. Is there an easy way to determine exactley what is wrong with the TPMS system?
