System Structure: Notes
WARNING: This page is about a different car, the 2009 Honda S2000 and 2008 Honda S2000. However, it is still accessible from the selected car via links, so may be relevant.
Once the vehicle speed exceeds 28 mph (45 km/h), the TPMS control unit monitors all four tires and the system. If it detects low pressure in a tire, it alerts the driver by turning on the low tire pressure indicator. If it detects a problem in the system, it turns on the TPMS indicator.
