- Summary
- Updated Freightliner Service Bulletin for Rewiring the MPC2 Camera Fuse. This bulletin replaces the version dated 9/15/20. Information has been added about raising the system voltage to normal range to clear the "Lost Communication to MPC" code. 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.
