What's wrong?
The engine control module, or ECM, on the 2023 Ic Bus Cesb is the computer that controls key engine functions. It reads engine signals and tells the diesel engine how to manage fuel, timing, and operation so the bus keeps running as commanded.
On affected buses, the ECM was built with damage inside the electronic circuit board. During production, a screw in a soldering fixture moved out of position and pushed a capacitor frame into the printed circuit board, which is the board that carries electrical signals inside the module. That damage can create an internal electrical short-circuit and cause the engine to stall.
The driver gets no normal warning before the problem happens. The bus can run normally until the ECM shorts and the engine stalls. There is no warning sign before failure.

Not every 2023 Ic Bus Cesb bus is on the list. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
An unexpected engine stall can raise crash risk because the bus loses power without a warning sign first. If the engine stalls while driving, pull over as safely as traffic allows, then contact an Ic Bus dealer for the ECM replacement. Repair is free at any franchised Ic Bus dealer.
What should I do?
- Check your VIN to confirm your 2023 Ic Bus Cesb is included in this recall.
- Contact a franchised Ic Bus dealer to schedule the free ECM replacement that addresses the engine-stall risk.
- Bring the recall notice if you have it. If not, reference recall number 22V610 when you call.
- Drive only as needed until the ECM is replaced, since an unexpected engine stall increases crash risk.
