Location 

The tire pressure monitor control unit is located in the toolbox in the left rear of the load compartment.

Task 

The following functions are realized by the tire pressure monitor control unit:

The tire pressure monitor control unit receives data packages by radio from the following sensors:

The data packages contain the pressure, tire temperature, individual serial number and status information (manufacturer, direction of rotation, operating mode etc.).

If a pressure loss is detected based on this data, the corresponding warning message appears in the multifunction display (A1p13) of the instrument cluster (A1).

The tire pressure monitor control unit continuously monitors all the inputs and outputs for faults. Detected faults that are relevant to function are entered into the fault memory.

Any status messages are shown in the multifunction display.

Direct entries 

Interior CAN (CAN B) 

The tire pressure monitor control unit is connected for exchanging data with the interior CAN.
