Component: Structure:body:door
Manufactured by: Neoplan Usa Corp.
Affected Units:: 54
An inductive voltage spike may affect the rear door time delay relay in a manner which causes the magnetic brake valve to energize. When this valve is energized the bus brakes are applied. Consequence of defect: if this occurs when the bus is in motion, the bus will brake unexpectedly without any action from the operator and may cause injuries to its occupants or cause an accident.
Install a new rear door time delay relay to prevent brakes from being activated at the wrong time.
System:rear door time delay relay. Vehicle description:buses with printed circuit boards and containing rear door time delay relay.
