Location
The tire pressure monitor control unit is on the underfloor above the rear axle.
Task
The tire pressure monitoring system control unit has the following tasks:
- Reading in of sensors and signals
- Evaluation of input factors
- Actuation of components
Reading in of sensors and signals
The input factors are read in via the following connections:
- Two-way radio
- Chassis CAN (CAN E)
Two-way radio
The following sensors are read in via radio:
- 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)
Chassis CAN
The following signals (from the IC (A1)) are read in over the chassis CAN:
- Vehicle speed signal
- Outside temperature
- kilometer reading
Evaluation of input factors
The input factors that have been read in are evaluated by the integrated microprocessor and the affected components are then actuated.
