Tire Pressure Monitor (TPM) System

The Tire Pressure Monitor (TPM) system alerts the driver of a large tire pressure change in any of the 4 tires, while vehicle is being driven. As visual warning sign, the TPM illuminates the tire pressure warning indicator on the instrument panel cluster (IPC).

The TPM system consist of 4 wheel mounted tire pressure sensor units, a tire pressure receiver, and a tire pressure warning indicator. Each tire pressure sensor unit consist of a sensor, tire pressure electronics, and power source.

The tire pressure sensor responds to a low frequency activation by transmitting in learn mode. When the tire pressure module receives a learn mode transmission while in Learn mode, it will assign that sensors ID to the location on the vehicle relative to the order in which it was learned.
