For diagnosing RFC (Rear Frame Computer) fault codes on an Iveco Stralis without expensive diagnostic tools, you can access the onboard display menu to view and interpret the specific error details. 1. How to Read Codes from the Dashboard

The Iveco Stralis allows you to navigate through its internal diagnostic menu using the steering wheel buttons or dashboard controls:

Accessing the Menu: Navigate to the "Diagnostics" or "Stored Anomalies" screen.

Reading the Display: Faults are typically displayed in four columns: DTC: The anomaly code (e.g., 1A, 02).

FMI: Failure Mode Indicator, which tells you the type of fault (e.g., 05 for open circuit, 06 for short circuit). OC: Occurrence Counter (how many times it happened). ACT: Status (Y for Active, N for Inactive/Stored). 2. Common RFC Fault Code Reference

The RFC module controls lighting and sensors at the rear of the vehicle. Common codes include:

RFC 1A 05: Number plate light open circuit (often a blown 10W bulb).

RFC 1B 05: Rear right position light open circuit (check 2x5W bulbs).

RFC 1E 12: Tail clearance/dimension light current too high (often due to wrong bulb wattage). RFC 1F 12: Left parking lights short circuit.

RFC 01 06: Rear Frame Computer power supply/grounding issue.

RFC 09 01: Air pressure sensor defect or wiring issue (common on APU units). 3. FMI (Failure Mode) Quick Guide

If you have a code not listed above, use the FMI number to understand the nature of the electrical problem: 02: Data erratic or incorrect signal. 04: Voltage below normal or shorted to low source.

05: Current below normal or open circuit (common for blown bulbs).

06: Current above normal or grounded circuit (short circuit). 4. Troubleshooting Steps

Check Bulbs First: RFC errors are frequently triggered by using the wrong wattage bulbs (e.g., 24V 21W instead of 5W). The RFC is highly sensitive to resistance changes.

Clear Inactive Codes: Some intermittent errors can be cleared by performing a "soft reset" (disconnecting battery terminals for ~1 minute), though active mechanical faults will reappear.

Inspect the APU: If the code relates to air pressure (RFC 09), inspect the Air Processing Unit (air dryer) located in the middle of the chassis.

Air pressure sensor fault: Defective sensor or broken wires, often caused by excessive air pressure in the air dryer unit. 1A 05 Number plate light: Open circuit (check for a 10W bulb). 1B 05

Rear right position light: Open circuit (check for 2x5W bulbs). 1E 12

Tail/Clearance lights: Output undercurrent (value too high). 1F 12 Left parking lights: Short circuit. N/A N/A

"RFC Not Communicating": Likely the rear control unit (Bosch box located behind the diesel tank) has failed or has a bad connection. How to Read Codes Without a Scanner

On most Stralis models, you can view active faults directly on the dashboard's IC (Instrument Cluster) display:

Turn the ignition to the ON position (do not start the engine).

Use the steering wheel menu buttons to navigate to "Diagnostics" or "Faults."

Select the RFC module to see specific active and stored DTCs. Troubleshooting Steps

Check Bulbs First: RFC faults are frequently caused by using incorrect bulb wattages (e.g., using a 21W bulb instead of 10W) or low-quality bulbs that the computer misinterprets as a short.

Inspect the Rear Frame Computer: The unit is a black and silver Bosch box located inside the chassis, typically behind the diesel tank. Check for water ingress or loose multi-plugs.

Soft Reset: You can sometimes clear "ghost faults" by performing a battery reset. Disconnect the positive battery cable for roughly one minute before reconnecting.

Air Dryer Sensor: If you have a code related to air pressure (DTC 09), inspect the sensor on top of the air processing unit in the middle of the chassis for leaks or wire damage. Stralis RFC fault - Iveco Daily Forums Below is a practical list of RFC codes

If you see an "RFC Anomaly" or specific DTC (Diagnostic Trouble Code), follow these steps to narrow down the cause:

Dealing with fault codes on an Iveco Stralis can be frustrating, especially when they disrupt your schedule. The RFC (Rear Frame Computer) module is critical because it manages everything from rear lighting and air suspension to trailer communication.

Below is a guide to understanding RFC faults and a list of common codes to help you troubleshoot your truck for free. What is the Iveco RFC Module?

The Rear Frame Computer (RFC) is located on the right side of the frame, just before the crossbeam. It acts as a bridge between the front controls and the rear components. When this unit detects a problem—like a blown bulb, a broken wire, or a faulty sensor—it sends a signal to the dashboard. Common RFC Fault Codes & Meanings

RFC codes often follow a standard format: a DTC (Diagnostic Trouble Code) followed by an FMI (Failure Mode Indicator). RFC Fault Code Description / Probable Cause DTC 01 FMI 05

Open circuit in the right front dipped beam (often shows as FFC/RFC conflict). DTC 1E FMI 12 Number plate light failure or circuit error. DTC 11

General Rear Frame Computer fault; often related to power supply or grounding. DTC 81 Short circuit to positive (+) at the output to valve Y1. RFC Red Box

Indicates a complete communication loss with the rear computer. Practical Troubleshooting Steps (Free)

Before heading to a dealer, try these steps to clear "ghost" faults or identify simple wiring issues: The "Soft Reset" Technique: Disconnect the positive (+) battery cable.

Touch the positive cable to the negative terminal (while the negative is still connected) for about 30 seconds.

Reattach the cable. This can clear static and reset the modules. Check the "Green" Corrosion:

Inspect the wiring harness near the RFC unit (right side of the frame).

Look for a thin brown wire about 15cm from the connector; this is a common failure point where wires rot and turn green. Inspect the Air Pressure Sensors:

RFC faults are frequently triggered by the air pressure sensor (the "chocolate" sensor) located near the four-circuit valve. Clean the contacts if they are dirty. Bulb Wattage Check:

The RFC monitors current. If you replaced a bulb with the wrong wattage (e.g., 10W instead of 21W), the system may trigger a fault. Where to Find More Resources IVECO Stralis RFC Fault Codes Guide | PDF - Scribd
