Information
Beginning in the 2014 model year, most vehicles completed the transition to the component part service name
Chassis Control Module in all publications and service tools, consolidating the former component part service
names of: Fuel Pump Control Module, Fuel Pump Flow Control Module, Fuel System Control Module and Fuel
Pump/Trailer Brake Control Module.
During this transition a limited number of vehicles will continue to reference the original component part service
names in Service Information (SI) diagnostics and schematics while the Electronic Parts Catalog (EPC) and GDS 2
may refer to the component part service names as Chassis Control Module. In order to help clarify the use of these
mixed references, the part service name Chassis Control Module, along with the original component part service
name which will be preceded by AKA:, will be used in the Service Programming System (SPS) and in Service
Information routing tables such as the Control Module References and Master Component Lists.
