Why does the trailer not reversestraight?

You can compensate for thetrailer drifting to the right or left byslowly turning the knob until the traileris following your desired path and thenholding the knob in that position.
Why does the system not detect asensor?
There could be an issue with theconnection, the wiring harness couldbe damaged, you could have multiplesensors connected or the sensor couldbe incorrectly installed. Check that the12-way connector is fully inserted intothe 12-way socket. The red rubber sealis not visible when the connector isfully inserted. Also check that thewiring harness sensor connection isfully inserted at the trailer sensor, andcheck for damaged wiring betweenthe 12-way connector and the trailersensor. Also, check that the sensor isinstalled on a vertical surface with thearrows pointing straight up.
