Body Cpc Fr Mercedes Actros MP2 MP3

Mercedes-Benz OE A0024462002 is an ECU 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 driving functions during operation via communication with the engine ECU and other modules on the CAN network.

Technical specifications

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

DIPA can intervene to refurbish these components thanks to its experience and expertise.

Functions

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

Model applications

• Mercedes-Benz Actros MP2/MP3

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 rev up

Final conclusions

The Mercedes OE A0024462002 is a CPC/FR (Fahrregelung) control unit typical of the Mercedes Truck electronic architecture, commonly found on Actros MP2/MP3. It is central to driving management because it calculates the torque request, distributes vehicle signals and coordinates speed regulation functions and network consents.
