What's wrong?
The chassis harness on the 2019-2021 Old Dominion Brush Co. Trailer Mount Unit and Tow Behind Unit trailers feeds power to the breakaway switch. That switch is the trailer's emergency backup: if the trailer separates from the tow vehicle, the breakaway cable pulls a plug and the switch sends battery power to apply the trailer brakes.
On affected trailers equipped with John Deere engines, the breakaway switch was wired to the starter side of the solenoid instead of the battery side. The starter solenoid is the electrical junction that routes power for engine starting. Because the harness was not lengthened for the new engine layout, and the solenoid was exposed, assemblers were able to connect the breakaway switch to the wrong terminal. When the breakaway cable plug is pulled, the emergency brakes do not engage.
There is no warning sign before failure. The issue shows up when the breakaway cable system is tested or when the trailer separates and the emergency brakes fail to apply.
