## NHTSA's summary

Thomas Built Buses Service Bulletin for DEF Connector Reinforcement Caps. Some customers experience separation of the diesel exhaust fluid \(DEF\) lines from the connection ports in extreme cold temperatures. To prevent this, a process was developed to secure the lines with wire ties. A new reinforcement cap has been developed to simplify this process at the DEF connection fittings.
