What's wrong?
The engine control module, or ECM, on 2016 International Durastar, Lonestar, Paystar, and Prostar trucks is the computer that manages key engine functions for the Cummins diesel engine. It reads signals from engine sensors and sends commands that keep fuel delivery and engine operation coordinated while the truck is running.
On the recalled trucks, the ECM can short circuit inside the module. Cummins traced the defect to printed circuit boards that were damaged while being assembled into the ECM case during production. A damaged board can create an internal electrical short, which shuts down the engine control module and stalls the engine.
There is no warning sign before failure. The engine can stall without warning, so an owner or driver will not get a dashboard cue or drivability symptom that reliably points to this defect before it happens.
