Tire Pressure Monitor: Notes

The Tire Pressure Monitor (TPM) is a system for monitoring the tire inflation pressure while the vehicle is being driven. For this purpose, the tire pressure and the tire air temperature are measured at certain intervals on request by the RDC control unit and telemetrically transmitted to the RDC aerial via a high-frequency transmission path. The RDC aerial forwards the signals back across the bus to the RDC control unit. The control unit evaluates the received data. It then forwards the information to the driver if necessary. The driver is thus informed of a necessary correction of the tire pressure or a puncture that might have occurred.
