Service bulletin SIL-3162

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

Altec has learned that trailers with incandescent lighting are not compatible with the Altec supplied trailer plug on certain Altec units mounted on Freightliner M2 Plus and Legacy Chassis built from 2023 to 2025. This can cause the trailer lights to not turn on. The Altec supplied trailer plug is rated for LED lights and meets build specifications.
