MODEL 204.9 with CODE (470) Tire pressure monitor (base) up to Model Year 2010 /Modification year 09, Fa. Schrader
Shown on model 204.0
Location
The tire pressure monitoring system control unit is located at the left in the trunk.
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 with the following connections:
- Two-way radio
- Interior CAN (CAN B)
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)
Interior CAN
The following signals are read in over the interior CAN:
- From IC (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 and the relevant components are then actuated.
Actuation of components
Components are actuated with the following connection:
- Interior CAN
Interior CAN
The following component is actuated via the interior CAN.
- Instrument cluster:
- Menu displays and warning messages
Design
The central antenna for receiving radio signals from the tire pressure sensors is integrated in the tire pressure monitoring system control unit.
