Operating procedure
Basic conditions:
- Circuit 15 ON
- The trailer is mechanically coupled.

1 The trailer's connecting line is plugged in to the trailer hitch socket, 13-pin (X58):
- Model 220 up to 4.99
The switching contact of the trailer recognition microswitch in the trailer hitch socket closes and switches ground to the trailer recognition control module (N28/1).

- Model 220 as of 5.99, model 203 and model 215
The circuits of the left trailer turn signal lamp and trailer stop lamps are energized briefly by the trailer recognition control module (N28/1).

2 The trailer recognition control module (N28/1) detects at the ground signal of the microswitch (model 220 up to 4.99) the trailer connected electrically to the closed circuit of the turn signal lamp and/or of the stop lamps.
3 The trailer recognition control module (N28/1) reports "Trailer connected" to the control module with rear fuse and relay module Fond (N10/2) or the rear SAM control module (N10/8) (models 215, 220) via the interior CAN".
4 The rear SAM control module with fuse and relay module (N10/1) or rear SAM control module (N10/8) (models 215, 220) activates the actuation and monitoring of the trailer lighting system.

Vehicles with code 220a PARKTRONIC
The signal "trailer connected" transmitted by the interior CAN causes the Parktronic control module (N62) to switch off the Parktronic sensors in the rear bumper.
