Truck Body Control Modules

This collection lists body and chassis control modules for heavy-duty commercial trucks from Freightliner, International, Kenworth, Peterbilt, Mack, Volvo, Western Star and other makes. Body and chassis modules manage lighting, cab functions and electrical loads, and they often act as a gateway between vehicle networks.

Identifying the correct replacement

Start with the OEM or manufacturer part number on the existing unit and search for it using the search bar. Similar-looking parts can have different part numbers depending on the truck model, engine, production date and optional equipment. These modules are frequently configured to the individual truck, so parameter programming may be required after replacement.

Condition, cores and programming

Each listing states the condition of the part and whether a core deposit or programming may be required. Use the truck-make links above to narrow the list to your truck, and contact our parts team with your truck details if you are not sure which part you need.
