u Understanding TrailerTRACS disconnections
A disconnect message sent from the vehicle to your companys computer indicates a
trailer is disconnected. There are three ways this message can be generated:
The disconnection is detected and the message is sent automatically. If a tractor
pulls multiple trailers, the disconnect message indicates all trailers.
There has been no signal from the TrailerTRACS transmitter for a preset time
period (approximately 2 to 5 minutes, depending on the number and types of
trailers). A disconnect message is sent automatically.
For trailers that are not equipped with TrailerTRACS hardware, you can send a
canned message indicating the trailer is disconnected. Check your companys list
of canned messages.
