What's wrong?
The engine control module on the 2023 Blue Bird All American School Bus is the computer that controls engine operation. It receives battery power through a fused circuit and sends the signals the engine needs to keep running. When it works normally, the module keeps engine commands steady while the bus is in service.
In this recall, the ECM has damage inside the unit. During production of the suspect modules, a screw in the supplier's soldering fixture backed out of place and pushed an electrolytic capacitor frame into the printed circuit board, the flat board that carries the module's electronic circuits. That damage can create an internal short-circuit, causing the engine to shut down unexpectedly and preventing the bus from restarting.
Blue Bird's filing lists no warning before this failure. There is no warning sign before failure, so the bus can lose engine power without a prior light, sound, or drivability change.
