# Service bulletin SB54\-355

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

Freightliner Service Bulletin for Inoperative Heated Mirrors Low Content BHM Vehicles.

On these vehicles, the heated mirror control circuit is hardwired \(non\-multiplexed\) instead of being controlled by the BHM \(multiplexed\).
