Hi my name is***** will be glad to try to help. Scroll through the display and let me know what you have for body controller fault codes.
Click below and see PDF page 21 for the procedure and let me know what you have for codes.
The Bulkhead modules have to be programmed after installation for your truck with the Freightliner software and there is no getting around that. They have the monopoly there unfortunately. Did they Program it in chassis?
882 Park / Marker Lights Output Fault 4,5,6 which means the Bulkhead module is not powering that circuit. Confirm by testing power from the module.
Click on this link for the test info. Also see PDF page 22 for the pinouts.
The Bulkhead Module is mounted on the cab side of
the frontwall and extends through an opening in the
frontwall into the engine side of the frontwall. The BHM
is located slightly below and outboard of the steering
The BHM has four harness connections on the engine
side of the frontwall and three harness connections on
the cab side. Connections on the engine side include:
• forward chassis harness
• engine harness
• two frontwall harnesses
Connections on the cab side include up to three dash
I have to head out for a while but I log in periodically in between jobs for follow ups. We can post back and forth as needed if you still need further help.
Thanks for the update. So we know the module is good. Start inspecting the harness from the firewall to the hood for corrosion and damaged connector pins and wiring. Look under any electrical tape for prior repairs ir pierced harness insulation from test light probing etc. It will likely be a harness issue you will finde if the module is powering those circuits.

Click on this link and verify all your fuses and relays are good as well as their connections. See PDF 16 and 17 for the fuse/relay chart. Also go into the instrument section to pull codes from the dash. Lets see what is logged through the dash display rather than the scan tool to see if it is anything different or more specific.
You need to press and hold the mode switch to get to the next screen for the full fault codes. 128 means theres and engine ECu fault logged and BH164 is for a fault logged in the bulkhead module. Let me know the faults.
Hi, Did you get this resolved?
