Component description for tire pressure monitor control unit - GF40.15-P-5124RF
Model 205, 253 with code 475 (Tyre pressure monitoring system)
Shown on MODEL 205.0
Location
The tire pressure monitor control unit is located on the underfloor above the rear axle.
Tasks
The tire pressure monitoring system control unit has the following tasks:
- Reading in of signals
- Evaluation of input factors
- Transfer of information
Reading in of signals
The input factors are read in over the following connections:
- Two-way radio
- User interface CAN (CAN HMI)
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)
User interface CAN
The following signals are received over the user interface CAN by the instrument cluster (A1):
- 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 whereupon the information is then sent.
Transfer of information
The tire pressure monitor control unit sends information via the user interface CAN to the instrument cluster and this information is then shown as menu displays and as warning messages.
Body
The central antenna is integrated in the tire pressure monitor control unit.
