# Service bulletin SB54\-336

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 Rewiring the MPC2 Camera Fuse. The multipurpose camera 2 \(MPC2\) power is supplied via fuse 14 \(F14\) in New Cascadia vehicles built before August 24, 2020. With this configuration, fault code 232/524127/9 \- "Lost Communication to MPC" becomes active during low voltage disconnect \(LVD\) situations when load shedding is required to maintain critical systems. These instructions provide the procedure for moving the MPC2 power supply from fuse 14 \(F14\) to fuse 35 \(F35\). Moving the MPC2 power supply requires the installation of a new etched vehicle power distribution module \(VPDM\) cover to document the new MPC2 location.
