GF80.20-P-4136RI Pneumatic Controller Unit With Combined Functions, Component Description

Component Identification:

Location
The e pneumatic controller unit with combined functions is located in the trunk on the left in front of the wheel recess.

Task
The pneumatic controller unit with combined functions has the following tasks:
^ Reading in of sensors, pickups and signals
^ Evaluation of input factors
^ Actuation of components

Reading in of sensors, pickups and signals The input factors are read in via the following connections:
^ Direct line
^ Interior CAN

Direct line
The following components are read in via a direct line:
- Trunk lid external operation switch (S88/8)
- RTC button (S62/26)
- Trunk lid emergency release switch (S88/10) (for code (494) USA version)
- Trunk partition "closed" limit switch (S69/10)
- Trunk lid locking switch (S134) (with code (887) Valet Parking)

Interior CAN
The pneumatic controller unit reads in information relevant for function over the interior CAN.

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.

Actuation of components
Components are actuated with the following lines:
^ Direct line
^ Interior CAN

Direct line
The following components are actuated with a direct line:
- Remote trunk opening CL valve (Y65/3)

Interior CAN
The pneumatic controller unit transmits request for function relevant actuations via the interior CAN.
