1) System overview: The Renault tyre pressure monitoring system comprises of 4 tyre pressure transmitters (1 on each valve), a central RF receiver and a control unit (ECU). The purpose of the system is to constantly monitor the individual tyre pressures and inform the driver of any faults within the system via the LCD dash display. Front Right Front Left Each valve emits an RF signal which carries its individual identification number (7 or 8 digit) and the measured tyre pressure. This signal will be emitted every hour when the vehicle is stationary, when the wheel is rotating at 20kmh+ or when there is a rapid loss of pressure. The valves are identified by a coloured ring fitted to the collar. Front Left – Green Front Right – Yellow Rear Left – Red Rear Right – Black 2) Tyre sets

Each valve sensor has a unique code and is matched to a particular wheel. This is programmed into the UCH control module. This enables a faulty wheel to be identified (given that the receiver can identify which wheel is transmitting). The sensor emits an RF (Radio Frequency) signal containing the valve code, status and tyre pressure. If wheels are to be swapped around then reprogramming will need to be carried out to identify the new position of the wheel. Each valve sensor has a coloured ring attached to the valve nut, each colour corresponds to a particular wheel position:
