Location
The PTS control unit is located behind the panel in the right luggage compartment.
Task
The PTS control unit has the following tasks:
- Reading in of sensors, pickups and signals
- Evaluating 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 (CAN B)
- Chassis CAN (CAN E) (via central gateway control unit (N93))
- Front end CAN (CAN G) (via central gateway control unit)
Direct line
The following sensors are read in via a direct line:
- Outer left front PTS ultrasonic sensor (B8/1)
- Center left front PTS ultrasonic sensor (B8/2)
- Inner left front PTS ultrasonic sensor (B8/3)
- Inner right front PTS ultrasonic sensor (B8/4)
- Center right front PTS ultrasonic sensor (B8/5)
- Outer right front PTS ultrasonic sensor (B8/6)
- Outer right rear PTS ultrasonic sensor (B8/7)
- Inner right rear PTS ultrasonic sensor (B8/8)
- Inner left rear PTS ultrasonic sensor (B8/9)
- Outer left rear PTS ultrasonic sensor (B8/10)
Interior CAN
The signals from the following components are received via the interior CAN:
- Trailer recognition control unit (N28/1) (on model 221.0/1 with code (550) Trailer hitch)
- Overhead control panel control unit (N70)
- Upper control panel control unit (N72/1)
Chassis CAN
The signals from the following control units are sent via the chassis CAN to the central gateway control unit and from there forwarded to the PTS control unit via the interior CAN:
- ESP control unit (N47-5)
- ME-SFI [ME] control unit (N3/10) (on gasoline engine)
- CDI control unit (N3/9) (on diesel engine)
- Intelligent servo module for DIRECT SELECT (A80) (read in over the drive train CAN (CAN C) by the ME-SFI [ME] control unit or the CDI control unit)
Front end CAN
The signals from the following control units are sent via the front end CAN to the central gateway control unit and from there forwarded to the PTS control unit via the interior CAN:
- Electric parking brake controller unit (A13)
Evaluating 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
The components are actuated via the following connections:
- Direct line
- Interior CAN
Direct line
The following components are actuated by the PTS control unit via a direct line:
- Outer left front PTS ultrasonic sensor
- Center left front PTS ultrasonic sensor
- Inner left front PTS ultrasonic sensor
- Inner right front PTS ultrasonic sensor
- Center right front PTS ultrasonic sensor
- Outer right front PTS ultrasonic sensor
- Outer right rear PTS ultrasonic sensor
- Inner right rear PTS ultrasonic sensor
- Inner left rear PTS ultrasonic sensor
- Outer left rear PTS ultrasonic sensor
- Rear PTS warning indicator (A44/3)
Interior CAN
The following components are actuated over the interior CAN:
- PTS warning indicator in multifunction display (A1p13) of instrument cluster (A1)
- COMAND controller unit (A40/3)
- Function LED in PTS OFF switch (S6/2s12) via the upper control panel control unit
The respective signals are read in by the central gateway control unit via the interior CAN and forwarded to the respective component via the central CAN (CAN F).
