Body Control Module Cpc Fr Actros Axor Atego

The Mercedes-Benz OE A0024460202 is a control unit of the CPC/FR (Fahrregelung) family. It is a network module that operates as an interface between driver controls, chassis systems and the powertrain, calculating torque requests and managing vehicle functions during driving by communicating with the engine ECU and other modules on the CAN network.

Technical specifications

• Type: CPC/FR control unit
• Vehicle electrical supply: 24 V (industrial vehicle application)

DIPA can service these components thanks to its experience and expertise.

Functionality

• Calculation of the torque requested by the driver (mainly from accelerator position) and transmission of the request to the engine ECU.
• Torque limitation under specific conditions (for example safety/traction control logics and compliance with the set speed limit).
• Determination and distribution of the vehicle speed signal to other systems via the network.
• Management of speed regulation functions (cruise and cruise with braking) with data exchange to brake modules (retarder where present).
• Management of consents and information to the gearbox/transmission.
• Auxiliary functions related to driving, with plausibility monitoring and emergency strategies if signals or communications are missing.

Model applications

• Mercedes-Benz Actros MP2/MP3/Atego/Axor

Typical faults

• The CPC does not communicate with the diagnostic tool and prevents communication with the other control units it is connected to
• The engine does not increase RPM

Final conclusions

The Mercedes OE A0024460202 is a CPC/FR (Fahrregelung) control unit typical of Mercedes Truck electronic architecture, recurrent on Actros/Atego/Axor. It is central to driving management because it calculates the torque request, distributes vehicle signals and coordinates speed regulation functions and network consents.
