Electrical Short in ECMs Prompts Truck Recalls

mixer truckSeveral vehicle manufacturers are recalling commercial trucks because they are equipped with a Cummins ISX12 or ISX15 engine that may have a defective Engine Control Module (ECM). These ECMs can experience an internal electrical short that can cause a fuse to blow, resulting in an unexpected engine stall without the ability to restart the engine; this increases the risk of a crash.

The Engine Control Module (ECM) may develop an internal electrical short circuit that could possibly blow a fuse in the ECM’s electrical supply circuit, resulting in an engine stall without warning. If this occurs, the engine cannot be restarted until the ECM and fuse are replaced.
