The PACCAR Continental MUX3-P Chassis Control Module is a central electronic controller used in Kenworth and Peterbilt trucks to manage chassis-level systems.
It acts as a communication and control hub for functions like ABS/traction control coordination, lighting signals, suspension inputs, PTO and chassis switches, and data sharing between other ECUs over the CAN network.
In simple terms, it’s the truck’s chassis “brain box”, helping all frame and stability systems work together and allowing fast diagnostics when faults occur
