Location 

The Parktronic (PTS) control unit (N62) is located on the left A-pillar under the instrument panel.

Task 

The Parktronic (PTS) control unit (N62) performs the following tasks:

• Reading in of signals 
• Evaluation of signals 
• Actuation of components 
• Sending signals 

Reading in of signals 

Signals are read in via the following connections:

• Direct lines 
• Chassis CAN (CAN E) 

Direct lines 

The signals from the following components are read via direct lines:

• Inner left rear PARKTRONIC sensor (B8/10)
• Center left rear PARKTRONIC sensor (B8/11)
• Outer left rear PARKTRONIC sensor (B8/12)
• Inner right rear PARKTRONIC sensor (B8/13)
• Center right rear PARKTRONIC sensor (B8/14)
• Outer right rear PARKTRONIC sensor (B8/15)
• Inner left front PARKTRONIC sensor (B8/16)
• Center left front PARKTRONIC sensor (B8/17)
• Outer left front PARKTRONIC sensor (B8/18)
• Inner right front PARKTRONIC sensor (B8/19)
• Center right front PARKTRONIC sensor (B8/20)
• Outer right front PARKTRONIC sensor (B8/21)

Chassis CAN (CAN E) 

The following signals are also read in by chassis CAN (CAN E):

• Circuit 15 status
• Wheel speed and wheel rotation direction
• Vehicle speed
• Reverse gear or gear range "R" engaged
• Gearshift lever or selector lever position
• Status of PARKTRONIC button (N74s2)
• Ambient brightness
• Status of combination switch (S4)
• Trailer recognition status
• ESP® status
• Left multifunction steering wheel button group signal (S110)
• Steering wheel angle
• Torque of electric power steering

Evaluation of signals 

The signals that have been read in are evaluated by the integrated microprocessor and the corresponding components are then actuated.

Actuation of components 

The following components are actuated by the PARKTRONIC control unit (PTS) (N62) via direct lines:

• Rear PARKTRONIC warning element (A44/3) (with code V36 (Headliner))
• Left front PARKTRONIC warning element (A44/7) (except code V36 (Headliner))
• Right front PARKTRONIC warning element (A44/8) (except code V36 (Headliner))
• Center front PARKTRONIC warning element (A44/9) (model 447.6/7)
• Inner left rear PARKTRONIC sensor (B8/10)
• Center left rear PARKTRONIC sensor (B8/11)
• Outer left rear PARKTRONIC sensor (B8/12)
• Inner right rear PARKTRONIC sensor (B8/13)
• Center right rear PARKTRONIC sensor (B8/14)
• Outer right rear PARKTRONIC sensor (B8/15)
• Inner left front PARKTRONIC sensor (B8/16)
• Center left front PARKTRONIC sensor (B8/17)
• Outer left front PARKTRONIC sensor (B8/18)
• Inner right front PARKTRONIC sensor (B8/19)
• Center right front PARKTRONIC sensor (B8/20)
• Outer right front PARKTRONIC sensor (B8/21)

Sending signals 

The Parktronic (PTS) control unit (N62) also transmits the following requests and information over the chassis CAN (CAN E):

• Request to output parking system display
• Request to output messages and warning tones
• Request to steer
• Remaining distance information
