Conclusion

Iveco Stralis RFC (Rear Frame Computer) system is responsible for controlling rear lighting, air suspension sensors, and chassis components. When it fails, you'll often see a red warning light and specific DTC (Diagnostic Trouble Code) combinations on your dashboard. Common RFC Fault Codes and Meanings Code (DTC) Likely Cause/Solution Air pressure sensor fault (System 1)

Defective sensor or broken wires on the Air Processing Unit (APU). Number plate light open circuit Burned-out bulb or wrong wattage used. Number plate light value too low bulb; using 5W often triggers this fault. Rear right position light open circuit Check bulb (standard 2x5W) or wiring harness. Left parking lights short circuit Wiring harness short to mass/ground. Right dipped light/rear direction open circuit Check rear direction light bulbs and connections. Key Troubleshooting Steps Check Bulb Wattage

: The RFC is highly sensitive to resistance. Many "faults" are actually caused by installing a bulb where a is required, especially for license plate lights. Inspect the APU

: If your air pressure gauge reads zero for the first circuit, the sensor is typically located on top of the Air Processing Unit (Air Dryer) in the middle of the chassis. Grounding Issues

: Corrosion in the rear light clusters is a frequent cause of "ghost" RFC errors. Communication Errors : If the RFC is "not communicating," check the CAN-H and L lines (Pins 10 on the BCB) for physical damage. Resources for Full Code Lists

DTC (Diagnostic Trouble Code) / FMI (Failure Mode Identifier) format on the instrument cluster.

: Identifies the specific component (e.g., number plate light).

: Identifies the type of failure (e.g., open circuit, short circuit). : Shows if the fault is currently active ( ) or inactive ( Common RFC Fault Codes and Meanings

The following table highlights frequently encountered RFC codes reported by drivers and technical manuals: Description Likely Cause / Solution Low air pressure (System 1)

Defective pressure sensor on the Air Processing Unit (APU) or broken wiring. Number plate light open circuit Blown bulb or disconnected wire. Check for a Number plate light value too low

Incorrect bulb wattage used. Often caused by using a 5W bulb instead of the required Rear right position light open circuit Faulty bulb or wiring for the right tail light. Left parking lights short circuit

Short to ground or positive in the left parking light circuit. Rear right brake pad wear sensor

Short circuit to ground. Check for corrosion on the RFC block or sensor pins. Common FMI (Failure Mode Identifier) Meanings

If you see a different DTC, the FMI suffix can help you diagnose the electrical nature of the problem: : Data erratic or intermittent. : Short circuit to positive. : Short circuit to ground. : Open circuit (broken wire or blown bulb).

: Component failure (incorrect resistance or "value too low"). Standard Troubleshooting Steps Check Bulbs First

: RFC faults are notoriously sensitive to bulb wattage. Ensure you are using the exact manufacturer-specified bulbs (e.g., for number plates, not 5W). Inspect Trailer Cables

: The "suzie" coils connecting the tractor to the trailer are common points for wire breakage, which can trigger multiple RFC lighting codes. Examine the APU Sensor

: For "System 1" air pressure errors (DTC 09), inspect the round connector on top of the Air Processing Unit located in the middle of the chassis. Clean Connectors

: Rear-frame components are exposed to road salt and moisture. Corroded pins in the RFC block or light housings are frequent culprits.

"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: Iveco Stralis stands for Rear Frame Computer

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

Report: Iveco Stralis RFC Fault Codes Guide 1. Introduction and Scope

This report outlines the RFC (Rear Front Controller / Body Computer) fault codes for the Iveco Stralis truck. The RFC, often functioning as the Body Computer (BCB) or associated with the FFC (Front Frame Controller), manages lighting, wiper systems, and various electrical signals. These codes are critical for diagnosing electrical, cabin, and lighting issues that often appear as "RFC Failure" or similar in the dashboard display. 2. Common RFC Fault Codes & Descriptions

Based on technical documentation, here are common RFC-related errors, often requiring immediate attention due to their impact on vehicle safety systems.

01 - Vehicle Communication Line: Indicates a failure or inactive status in communication between the body computer and other modules.

09 - Power Supply - Low Voltage: Indicates a power supply issue to the RFC, often resulting in erratic electronic behavior.

16 - Control Unit, BCB Data Link: Indicates an unknown or loss of communication with the Body Computer.

11 - Air Motor Windscreen: Short circuit to positive detected in the windscreen wiper system.

13 - Recycle Motor/Blocked Flap: Indicates a malfunction in the HVAC system's air recirculation flap.

0105/0106/0405 - Lights Malfunction (Dipped Beam): Open circuit or short circuit in right/left dipped headlights.

0905/0912 - Right Direction Indicator: Open circuit or low value detected in the indicator circuit.

1705/1706/1712 - Rear Foglight: Open circuit, short circuit, or low value detected.

2202 - BCB CAN Line: Communication failure between the body computer and the rest of the CAN network. 3. Diagnosis and Troubleshooting

When a code is active (e.g., 0405 - Dipped Beam Left Active), it indicates a persistent problem. If "inactive," it suggests an intermittent issue.

Wiring Inspection: Inspect all connectors for corrosion, particularly around the RFC box and the main fuse panel.

Ground Connections: Check for poor ground connections on sub-harnesses, which can cause phantom codes.

Relays and Fuses: Verify all fuses related to lighting, wipers, and the body controller are intact.

Resetting ECU: After repairs, it may be necessary to disconnect the battery for approximately 15 minutes to clear stored fault codes. 4. Common Causes

Chafed wiring harness (often near the radiator area or under the cab). Corroded pins in the RFC connector box. Bad ground connection on sub-harnesses. Failed electrical motor (e.g., wipers or flap motors). 5. Disclaimer

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.

Step 4: Reset RFC Learned Values (Free with diagnostic tool demo)

After replacing any fuel component, you must reset the RFC adaption. Using a free tool like Multi ECU Scan (demo mode):

  1. Connect to EDC17 (Stralis Euro 5/6).
  2. Navigate to Special Functions.
  3. Select "Reset Fuel Metering Unit Adaption."
  4. Perform a key-off for 10 seconds.
  5. Start engine and idle for 5 minutes.

Doing this clears phantom RFC codes caused by old learned values.

What is the RFC System on an Iveco Stralis?

Before diving into fault codes, it is essential to understand what the RFC system does. RFC stands for Regeneration Fuel Control. It is a subsystem within the after-treatment setup (specifically the SCR – Selective Catalytic Reduction and DPF system).

The RFC system is responsible for:

  1. Injecting fuel into the exhaust line to raise temperatures for DPF regeneration.
  2. Controlling the post-injection of diesel fuel to burn off soot trapped in the filter.
  3. Monitoring pressure differentials to ensure the DPF is not clogged.

When the RFC system malfunctions, the truck may enter "limp mode," reduce engine power, or increase fuel consumption dramatically.

How to Clear RFC Fault Codes (Free Methods)

Once repaired, codes can be cleared without a dealer tool:

  1. Ignition cycle method: Turn ignition ON for 30s → OFF for 60s → repeat 3x. Some intermittent codes will clear.
  2. Battery disconnect: Disconnect both batteries for 20 minutes (resets ECU volatile memory). Be warned: You may lose learned adaptations.
  3. Free software clear: Using TruckDiag Lite + ELM327, select "Clear DTCs" under Fuel System.
