For a detailed list of specific numeric fault codes (e.g., 01, 02, etc.), you may need to refer to the IVECO Stralis RFC Fault Codes Guide or use a professional scanner.
| Abbreviation | Meaning | Description | | :--- | :--- | :--- | | | Diagnostic Trouble Code | This is the main code that identifies the specific circuit or sensor with a problem (e.g., DTC 16, DTC 1A). | | FMI | Failure Mode Identifier | This is a two-digit number that describes the type of failure (e.g., 05 = open circuit, 12 = short circuit). | | OC | Occurrence Count | This number indicates how many times the fault has been detected by the computer. | | ACT | Active Status | This tells you if the fault is currently happening. "Y" means "Yes, the fault is Active," while "N" means it is a stored (intermittent) fault. |
The wiring harness running along the chassis rail to the rear of the truck is highly susceptible to road debris, vibration, and moisture. Inspect the harness for chafing, exposed copper, or tight bends that could break internal wires. 3. Inspect Trailer Connections

: A faulty engine oil pressure sensor or air pressure sensor can trigger RFC errors. Connector Integrity
Iveco diagnostic systems typically present codes in two formats depending on the generation of your Stralis (Stralis AS, AT, AD, or Hi-Way):
If your IVECO Stralis is showing codes (often related to the SCR / AdBlue system or aftertreatment ), here's what you should know:
When an RFC light appears, begin with simple checks: verify all rear lights (tail lights, brake lights, turn signals) and trailer connections. Inspect wiring harnesses for damage, paying close attention to the harness behind the mudguards and the connector at the Air Processing Unit. What (e
: Left/Right rear indicator circuit fault. Usually caused by a blown bulb or a corroded light cluster socket.
So, what exactly does the RFC control?
To help narrow down the exact issue with your truck, please tell me the showing on your display, the year of your Stralis , and whether you are experiencing any physical symptoms like blinking dashboard lights or dead trailer circuits. Share public link
Below are some of the most frequent RFC-related fault codes encountered by owner-operators and fleet mechanics. 1. Air Suspension & Axle Codes (ECAS) | | FMI | Failure Mode Identifier |
A reading of 120 ohms indicates an open circuit (broken wire), while 0 ohms indicates a short circuit. When Does the RFC Need Replacement?
A unique number that identifies the specific component or circuit that is failing.
Fault in the left turn signal circuit or light setting actuator. Right Rear Position Light / Horn
The wiring loom running from the cab to the RFC often chafes or breaks within the protective corrugated tubing.
Iveco Stralis trucks use a standardized format for displaying diagnostic trouble codes (DTCs). Understanding this format is essential for accurate troubleshooting.
