Service Bulletin/Repair Instructions
Emissions Recall: Cummins DEF Sensor Shortage
Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

Emissions Recall: Cummins DEF Sensor Shortage
511452
FCCC X-Line chassis, equipped with a certain rear mounted Power Distribution Module (PDM), may experience cracked internal solder joints, which after a period of vehicle use may lead to intermittent open circuits, in which the rear marker lights, brake lights, or left turn signal lights may not function. Brake lights that do not function correctly may not notify motorists of a braking event, which may lead to an increase risk of crash. A secondary fused harness will be added which bypasses the affected suspect portion of the PDM. Repairs will be performed by Daimler Trucks North America authorized service facilities.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
