Service bulletin SB1744

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Field Change Program: It has come to the attention of Van Hool that the fire suppression system, when activated while driving, shuts down the engine after 15 seconds. As a result of this, the door brake is automatically applied. To prevent this from happening while driving, it is necessary to load the newest version of the multiplex program.
