Indicates an unknown or loss of communication with the Body Computer.
While this guide gives you the tools to understand , some situations still require professional intervention:
The is precise, but not mysterious. With the free fault code list , dashboard diagnostics , and simple electrical tests provided in this guide, you can troubleshoot 80% of RFC issues without visiting a dealer.

This blog post is for informational purposes only and is not intended to be a comprehensive guide on Iveco Stralis RFC fault codes. The information provided may not be accurate or up-to-date, and we encourage readers to consult official Iveco documentation and seek professional advice for specific repair needs.
The primary peripheral control units are the and the RFC (Rear Frame Computer) . The FFC is responsible for the vehicle's front lights, sensors, and some under-hood components. Conversely, the RFC is the master controller for the entire rear electrical system of the tractor unit, including:
Short circuit or open circuit on the left rear marker/running light. Indicates an unknown or loss of communication with
Do not waste time on free software cracks. If you are a DIY mechanic, invest in a dedicated heavy-duty truck scanner (like an Autel MS908CV) or join a dedicated Iveco technical forum where members can translate specific codes for you based on your symptoms.
After replacing any fuel component, you must reset the RFC adaption. Using a free tool like (demo mode):
In IVECO’s proprietary diagnostic structure (often accessed via or ModiEco software), RFC refers to the Fuel Injection System control unit logic. It is a subset of the EDC (Electronic Diesel Control) . Iveco trucks are highly susceptible to wiring degradation
Unscrew, clean away rust with a wire brush, apply dielectric grease, and re-torque.
RFC (Rear Frame Computer) in an Iveco Stralis manages critical rear-chassis functions, including lighting, axle pressure, and suspension sensors. When an RFC fault appears, it typically follows a format like DTC XX FMI YY
The command to inflate or deflate the air bags is failing. Check for a corroded plug at the rear valve block assembly. Step-by-Step Diagnostic Strategy for RFC Codes
: Related to the rear lighting or side direction lights. 1401 : Supply pressure sensor fault. Diagnostic Indicators (FMI Codes)
When a short circuit, an open circuit, a bulb failure, or a loose connector occurs on any of these systems, the RFC generates a fault code and alerts the driver via the onboard dashboard display. Understanding the Structure of Iveco Fault Codes
