I have a 2009 Subaru Forester. For about the last 6 months the tpms light is coming on. It starts flashing and then stays on for a while then goes off. I understand 10 years or 100k miles is the life of the sensors. Is there or what type of diagnostic equipment is needed to diagnose my problems. Is there a universal tool or is it brand sprcific? What is needed to reset new sensors?
My research shows tools for GM products but I don't know what is needed for a Subaru.
