Tire Pressure Monitor (TPM) System
NOTE:
This system may also be referred to as the low tire pressure warning system. The instrument cluster may also be referred to as combination meter.
During driving at speeds above 25 mph (40 km/h), the low tire pressure warning system receives the signal transmitted from the transmitter installed in each wheel. The sensor-transmitter integrated with a valve transmits a detected air pressure signal in the form of a radio wave. The remote keyless entry receiver receives the air pressure signal transmitted by the transmitter in each wheel. The Body Control Module (BCM) reads the air pressure signal received by the remote keyless entry receiver, and controls the warning light. It also has a judgement function to detect a system malfunction.
CAUTION:
Ensure there is no metallized film or any metal parts (antenna, etc.) on the windows, as this may cause poor reception of the signals from tire pressure sensors, and the TPM system will not function properly.
