Service bulletin SB1650

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

To check rating of lower-deck evaporator fans circuit-breakers for TDX25US coahes.On some of the TDX25US coaches the evaporator fans located in the lower deck climate control unit are protected by four 15 amp circuit breakers. Field reports have determined that at very hot operating conditions these circuit breakers trip too fast. To prevent this from happening, Van Hool is conducting a field change program by which first the rating of these circuit breakers has to be checked and, if necessary, the circuit breakers have to be replaced by 20 Amp circuit breakers according to the step-by-step instructions given in this service bulletin.
