Component Description For Tire Pressure Monitor Control Unit - GF40.15-P-5124RF
Model 205, 253
with code 475 (Tyre pressure monitoring system)
Shown: 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
- Sending signals
Reading in of signals
The input factors are read in via the following connections:
- Two-way radio
- User interface CAN (CAN HMI)
Two-way radio
The signals from the following components are read in via radio connections:
- 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 from the instrument cluster (A1):
- Vehicle speed signal
- Outside temperature
- Kilometer reading
Evaluation of input factors
The read in input factors are evaluated by the integrated microprocessor, whereupon the signals are then sent.
Sending signals
The tire pressure monitor control unit sends requests for display of messages and warnings to the instrument cluster via user interface CAN.
Structure
The central antenna is integrated in the tire pressure monitor control unit.
