GF54.65-P-5001CE PARKTRONIC Control Unit Component Description
- with CODE (220) PARKTRONIC

Component Identification:

Location
The PARKTRONIC control unit is located in the front passenger footwell.

Task
The PARKTRONIC control unit performs 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 with the following connections:
^ Direct line
^ Interior CAN (CAN B)

Direct line
The signals from the following components are read via a direct line:
- Outer left front PARKTRONIC distance sensor (B8/1)
- Center left front PARKTRONIC distance sensor (B8/2)
- Inner left front PARKTRONIC distance sensor (B8/3)
- Inner right front PARKTRONIC distance sensor (B8/4)
- Center right front PARKTRONIC distance sensor (B8/5)
- Outer right front PARKTRONIC distance sensor (B8/6)
- Outer right rear PARKTRONIC distance sensor (B8/7)
- Inner right rear PARKTRONIC distance sensor (B8/8)
- Inner left rear PARKTRONIC distance sensor (B8/9)
- Outer left rear PARKTRONIC distance sensor (B8/10)

Interior CAN
The following signals are read in over the interior CAN:
- By the front SAM control unit with fuse and relay module (N10/1):
- PARKTRONIC button status (N72/1s8)
- Light sensor status (B38/1) (without code (345) Rain sensor)
- Rain/light sensor status (B38/2) (with code (345) Rain sensor)
- Parking brake indicator switch status (S12)
- Backup lamp switch status (S16/2) (for model 204.0/2 with transmission 711, 716)
- Transmission selection lever position (for transmission 722) provided by the CDI control unit (N3/9) (for diesel engine) or from the ME-SFI [ME] control unit (N3/10) (for gasoline engine)

- Provided by instrument cluster (A1):
- Vehicle speed signal

- Provided by trailer recognition control unit (N28/1) (with code (550) Trailer hitch):
- "Trailer detected" status message

- Provided by the Electronic Stability Program control unit (N30/4):
- Left front axle rpm sensor signal (L6/1)
- Right front axle rpm sensor signal (L6/2)
- Left rear axle rpm sensor signal (L6/3)
- Right rear axle rpm sensor signal (L6/4)

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 lines:
^ Direct line

Direct line
The following components are actuated via a direct line:
- Rear PARKTRONIC warning indicator (A44/3)
- Dashboard PARKTRONIC warning indicator (A44/4)
