Tire Monitoring System: Description and Operation

Tire Pressure Monitoring System

CAUTION! Tires with emergency running characteristics are only installed in conjunction with a tire pressure monitoring system.

Tire pressure monitoring with pressure sensor





The wheel electronics, that is, the system pressure sensor, forms a physical unit with the valve.

The pressure sensor transfers the recorded signals to the tire pressure monitoring system antenna.

The pressure sensor is connected firmly to the rim with a threaded connection.

If the tire pressure drops, the driver is warned via the pressure sensor in the instrument cluster.





Tire Pressure Monitoring System
To inform the driver, this system transfers the tire pressure values via a control module to the driver information system in the instrument cluster.

Depending on vehicle and type of pressure loss, different indicators are shown there.

Currently, there are 2 different sensor versions.
^ 1. Version for Allroad MY 2001, RS6 MY 2004, Audi A8 MY 1994, Audi A8 MY 2003.
^ 2. Version for all other models.

Note:
^ If vehicles with tire pressure monitoring sensors are transported in airplanes, the airline must be informed of the sensors.
^ The correct allocation must be observed, otherwise the tire pressure monitoring will not function correctly.

Tire pressure monitoring with wheel speed sensor
When the tire pressure decreases, the speed of the respective tire changes.

The changed tire speed is recorded by the speed sensor.

The driver is informed of the changed tire pressure in the instrument cluster.
