What's wrong?
The ignition interlock on 2022-2024 Micro Bird T-Series School Bus vehicles is a starter lockout tied to the rear emergency door. Its job is simple: when the anti-vandal lock is engaged on that door, the bus should not start. That keeps a bus from being put into service while an emergency exit is locked.
On affected buses, the wiring logic for the Ford Transit starter circuit changed the path used by the interlock. If the key is inserted while the rear emergency door is unlocked, then the door is locked afterward, the warning buzzer sounds but the engine can still start. That means the lockout no longer blocks starting in that sequence, which is why the buses do not meet the emergency-exit requirement in NHTSA campaign 24V841.
There is no warning sign before failure. The detectable clue is the inspection behavior itself: the buzzer sounds, the rear emergency door is locked, and the engine still starts.
