What's wrong?
The engine control module, or ECM, on the 2016 Peterbilt trucks in NHTSA campaign 15V597 is the electronic controller that manages engine operation. It reads sensor signals and sends commands that keep the engine running as the driver accelerates, cruises, and idles.
In the recalled trucks, the problem starts inside the ECM case. During assembly, a screw was misaligned while printed circuit boards were installed, and that damaged the boards. Printed circuit boards are the internal pathways that carry electrical signals through the module. Damage there can create an internal short circuit, and when the ECM shorts internally, the engine stalls without warning.
The affected ECMs are identified by serial number, which is how the recalled parts are separated from the remedy parts. There is no warning sign before failure. The truck can feel normal until the short circuit happens and the engine shuts down.
