Whenever the engine is running, the TPMS control unit continuously monitors all four tire pressure sensors and the system. If it detects low pressure in a tire, it alerts the driver by turning on the low tire pressure indicator and the appropriate tire indicator. If it detects a problem in the system, it turns on the TPMS indicator and the low tire pressure indicator (start brinking).
