What's wrong?
The MC43 module on 2022-2023 Nova Bus Lfs transit buses is an electronic control module in the bus propulsion control system. It receives and processes operating messages from other onboard systems so the bus can manage propulsion and related vehicle functions while in service.
On affected buses, the Nova Bus telemetry control unit was installed in parallel with a customer-specific vehicle monitoring system. That setup sends too much data toward the MC43 module. The electronic architecture allows the module to overflow with messages, and the MC43 module can shut down when it cannot process that data flow.
There is no warning sign before failure. The bus can shut down in service before the driver has a warning light, message, or other clear notice that the control module is about to stop working.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific bus.
What's the safety risk?
If the control unit shuts down, the bus loses drive power, which increases the risk of a crash. There is no warning sign before failure, so operators should treat any loss of propulsion as a reason to stop in a safe place and contact service. Repair will be free at any franchised Nova Bus dealer once available.

What happens at the repair
