What's wrong?
The front entrance door on 2008-2011 Thomas Built Buses Saf-T-Liner C2 school buses is air operated, so air pressure moves the door open and closed for loading. A reed switch is the small position sensor that tells the bus whether that door is open or closed. The warning light and crossing arm system depends on that door-position signal.
On affected buses, the reed switch can malfunction and send the wrong signal about the front entrance door position. When that happens, the warning lights and crossing arm do not follow the door operation correctly during student loading and unloading. That creates a safety problem at the exact moment students are entering or leaving the bus.
There is no warning sign before failure. A driver or fleet operator can discover the problem only when the warning lights or crossing arm fail to operate as expected during a door cycle.
