1. SYSTEM OVERVIEW

The tire pressure monitoring system (referred as TG for Tire Guard = TG1C_G3) consists of
the following units:

- Tire guard wheel unit type TIS-15 which includes an integrated pressure, temperature and
acceleration sensor and a RF transmitter.

- LF receiver unit which includes a LF receiver (not described in this document)
The TG monitors a vehicle's tire pressure whilst driving or stationary. An electronic unit
(wheel unit) inside each tire, mounted to the valve stem, periodically measures the actual tire
pressure.
By means of RF communication, this pressure information is transmitted to the RF
transmitter.
