Trailer anti-theft device, function
Operating procedure
Basic conditions:
- The trailer recognition control module (N28/1) has detected the coupled trailer.
- The vehicle is locked and the anti-theft alarm system (ATA) primed.
- The trailer recognition control module has detected the activated ATA.
- The trailer recognition control module monitors the trailer's stop lamps (2 and 3) by applying current to them cyclically.
- The electronics of the trailer recognition control module (N28/1) detects a discontinuity in the stop lamp circuit and immediately sends via the interior CAN the "Alarm" signal to the rear SAM control module with fuse and relay module (N10/2) or to the rear SAM control module (N10/8).
- The rear SAM control module with fuse and relay module (N10/2) or rear SAM control module (N10/8) evaluates the signal and triggers the acoustic and optical alarm:
The rear SAM control module with fuse and relay module (N10/2) or rear SAM control module (N10/8) actuates the alarm signal horn with additional battery (H3/1) and rear lighting devices directly for an acoustic and optical alarm display.
Model 203
Actuated by the interior CAN, the front SAM control module with fuse and relay module (N10/1) triggers the optical alarm display of the front lighting devices.
Models 215/220
Actuated via the interior CAN, the left front SAM control module and right front SAM control module (N10/6 and N10/7) trigger the optical alarm display of the front lighting devices.
