Toyota vehicles prior to 2009 are equipped with a Tire Pressure Warming Reset that can be used for initialization. When the bottom is pushed and held for more than 3 seconds, the vehicles receivers are open and looking for the currently stored TPMS IDS.What if there is a missing or broken sensor?What if there are new sensors on the vehicle that haven’t yet been programmed?This will cause these vehicles to become stuck in a loop, searching for TPMS IDS that are no longer there.N2 USA has developed the Toyota Loop Reset tool to hands this issue.
