What to do if Trailer Vision Security System shows 'No Signal'?
- AalvaradotammyAug 1, 2025
If your Trailer Vision Security System monitor displays a 'No Signal' message, it could be due to a couple of reasons. First, check that the corresponding camera(s) are receiving power by inspecting the lighting circuit and ensuring power is available at the camera. Also, verify the camera wiring, paying close attention to the correct polarity connections. Another potential cause is that the channel or monitor isn't paired with the camera. To pair them, select reverse, turn the hand brake ON, and then press the camera pairing button.
