Rear axle sensors, differential lock actuators, and license plate illumination.
Inspect the 15-pin or 7-pin trailer plug and socket on the back of the tractor unit. Moisture, road salt, and bent pins frequently cause the RFC to misread the power draw of the trailer's lights, logging an active fault. Cleaning and applying dielectric grease to the connector often solves this issue.
If you see an RFC code, follow these steps to narrow down the issue:
I can provide the exact wiring schematic references or sensor pinouts for your specific fault code. Share public link
Before inspecting the rear frame, open the main electrical distribution board located in the passenger-side dashboard. Check all fuses labeled for the RFC, rear lighting, and trailer interface. A simple blown fuse can trigger multiple terrifying fault codes. Step 2: Inspect the Rear Chassis Ground Points iveco stralis rfc fault codes free
(e.g., suspension not working, rear lights staying on)? What is the year of your Stralis? IVECO Stralis RFC Fault Codes Guide | PDF - Scribd
Electrical supply and signals sent to the towed trailer.

To retrieve RFC fault codes, you'll need a diagnostic tool specifically designed for Iveco vehicles. Some popular options include: Rear axle sensors, differential lock actuators, and license
Measure between the CAN-High and CAN-Low pins at the diagnostic port or the RFC plug. You should see approximately 60 Ohms .

Shows how many times the fault occurred and whether it is currently active (Y = Yes, N = No). How to Access RFC Fault Codes for Free
The of your Stralis (e.g., Euro 5, Euro 6, Hi-Way) Cleaning and applying dielectric grease to the connector
By using your Iveco Stralis's onboard dashboard diagnostic menu and checking the physical wiring integrity at the rear frame, you can successfully resolve many RFC fault codes completely free of charge.
The RFC monitors electrical resistance to ensure bulbs are working. If you replace traditional halogen tail lights with modern LED units without installing load resistors, the RFC will assume a bulb is blown and throw an open-circuit fault code. Free and Low-Cost Tools for Clearing IVECO RFC Codes
To resolve these issues, technicians may:
The most common cause is a broken wire. Check the wiring harness where it passes over the rear axles.
