What's wrong?
The signal converter on 2015-2025 Utilimaster Truck Body vehicles is an electrical module for the rear lighting system. It combines the turn-signal and stop-lamp circuits into one output that feeds the rear lights, so the lights behind the truck show braking and turning correctly. The converter is mounted underneath the truck body.
On affected trucks, the converter can fail because of incorrect assembly during manufacturing. The recall describes a repair that adds watertight seals at the wiring connection points for the signal converter. If the module or its connections stop carrying the lighting signals correctly, the brake lights and turn signals at the rear of the truck stop working.
There is no warning sign before failure. The driver gets no warning message or identifying signal before the converter stops working. Once it fails, people behind the truck lose the brake-light and turn-signal cues they rely on.
