Short circuit detected in the trailer reverse light circuit. Trailer Indicator (Right)
When encountering an RFC fault code, follow these steps:
Measure resistance across the CAN High and CAN Low wires at the diagnostic plug or RFC harness.
Complete Guide to Iveco Stralis RFC Fault Codes: Diagnosis and Troubleshooting iveco stralis rfc fault codes
Encountering an "RFC" fault on your Iveco Stralis can be unsettling, but it is rarely a reason for panic. Most often, it is a sign of a straightforward electrical fault—a burned-out bulb, a chafed wire, or a failing sensor. By understanding the role of the Rear Frame Computer, learning how to use your dashboard's diagnostic tools, and following a systematic approach to troubleshooting, you can quickly demystify these codes and get your truck back on the road.
: This method is excellent for reading codes and understanding an active problem. Do not attempt to clear permanent faults without a proper diagnosis tool, as this may only hide the symptom.
However, when the issue points to a deeper problem like a faulty RFC computer or complex CAN-bus errors, professional intervention is necessary. Dealership-level scanners can run guided diagnostics, perform component activations, and access technical bulletins. A professional can also safely reset learned values after component replacement.

Check the wiring harness where it passes over the rear axles. Vibration often causes the insulation to rub through, grounding out the signal wires.
The (particularly models equipped with HI-SCR and Euro 6 engines) uses an RFC (ReGen Fuel Catalyst) system. The RFC is a fuel-borne catalyst dosing system designed to assist the Diesel Particulate Filter (DPF) regeneration process.
Additionally, advise drivers to avoid frequent engine shutdowns when the light is on. Interrupting regeneration is the number one cause of RFC 001. Most often, it is a sign of a
In some Iveco technical documentation, RFC also loosely refers to the , but for fault code purposes, it is almost exclusively linked to aftertreatment and fuel management.
Signal too low (often caused by road grime or a loose sensor).
Below is a list of frequently encountered for the Stralis (Euro 5/Euro 6). Note that Iveco often prefixes codes with “RFC” in diagnostic tools, but the underlying SPN/FMI is standard.
Check the entry points where wires enter the protective "corrugated" tubing, as they often snap due to vibration. Iveco Форум
