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:
- Tire pressure temperature compensation
- Display of a soft warning for slight pressure loss
- Display of a hard warning for significant pressure loss
- Warning in event of rapid pressure loss
- Automatic fill detection
- Status monitoring
The tire pressure monitor control unit receives data packages by radio from the following sensors:
- Left front tire pressure sensor (A69/1)
- Right front tire pressure sensor (A69/2)
- Left rear tire pressure sensor (A69/3)
- Right rear tire pressure sensor (A69/4)
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.
