SUBJECT
Third Generation Tire Pressure Monitor System (RDC)
MODEL
E90, E91, E92, E93 (3 Series) from 9/09 production
INFORMATION
As of September 2009 production, a new generation Tire Pressure Monitor System has been introduced for all 3 Series models. Although the basic
operation of the system is similar to the previous version, there are several key differences between the two systems.
The new system consists of five components:
^ One central antennae with an integrated control module (5) mounted in the right rear wheel arch
^ Four wheel electronics (1-4) mounted at the base of each tire valve.
Central antennae with integrated control module

The control module and central antennae have been combined in a single housing. This new control module has the ability to send request for
information to each of the 4 wheel electronics via a low frequency single (125 kHz). This eliminates the need for separate transmitters, as used for
previous systems.
New style wheel electronics
The wheel electronics consist of plastic housing with integrated circuitry. The following items are contained within the wheel electronics:
^ Pressure sensor
^ Temperature sensor
^ Acceleration sensor
^ Transmitter/receiver unit
^ Self-diagnosis controller
^ Battery
The following points should be considered when diagnosing and/or servicing the system:
^ The system components are not interchangeable or compatible with previous versions.
^ The type of wheel electronic fitted can only be determined via visual inspection.
^ The detection of low tire pressure and the subsequent warning is similar to the previous design.
^ The reset procedure has changed.
Special Note for Reset Procedure
After initiating a reset, the vehicle must be driven for a period longer than 12 minutes with a vehicle speed which exceeds 19 mph (~30 km/h).
