# Service bulletin SB923\-1

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

TriPac 3 units with the Aftertreatment Device \(ATD\) option may have Alarm 367 FMI 7 at initial startup. This is a nuisance alarm until the unit reaches over 20 hours of run time. The ATD muffler needs to build back pressure for the alarm to clear. Alarm 367 FMI 7 would show up in the datalogger as a lot of set/clears as the unit builds up backpressure properly.
