The RFC (Rear Frame Computer) in an Iveco Stralis manages critical rear-vehicle functions like lighting, air suspension, and axle pressure sensors. When an RFC fault occurs, the dashboard typically displays a specific code format, such as DTC 09 / FMI 01. Common RFC and Related Fault Codes
While "RFC" specifically refers to the rear frame module, it often interacts with the FFC (Front Frame Computer) and the BC (Body Computer). Below are common codes seen in these systems: iveco stralis rfc fault codes free
RFC DTC 09 / FMI 01: Often indicates an issue with the front axle air pressure sensor or related wiring, which may cause the gauge to read zero.
0105 / 0106: Right side dipped beam open circuit or short circuit. 0405 / 0705: Left side dipped beam open circuit.
0900 / 0901: Front axle pressure sensor value above or below limit. 1401: Supply pressure sensor fault. 1705 / 1706: Rear fog light open or short circuit. 2108: Pneumatic horn power supply open circuit. Understanding the RFC Pins (Rear Frame/Body Computer)
The RFC and Body Computer use specific signal pins to control the vehicle's rear lighting and sensors: Pin 5 & 7: Rear position lights (Left/Right). Pin 6 & 18: Rear direction lights (Left/Right). Pin 13: Rear fog lights. Pin 10: CAN-High & Low (BCB) communication lines. How to Access Codes
You can view these codes directly on your dashboard by navigating to the Diagnostics menu using the steering wheel or dash controls. For a full diagnosis or to clear inactive "ghost" codes, a professional scanner is recommended.

Rear Frame Computer (RFC) on an Iveco Stralis is a critical control unit responsible for managing the electrical systems at the back of the truck, including rear lighting trailer connections air suspension sensors braking components
. When the RFC light appears on the dashboard, it often signals a simple bulb failure or a more complex wiring issue in the rear chassis. Understanding the Fault Code Structure Iveco Stralis fault codes are typically displayed in a
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 Executive Summary: Proceed with Caution If you are
: 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.

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

Iveco Stralis stands for Rear Frame Computer . This module is responsible for managing the rear external lighting (brake lights, plate lights, indicators), air suspension (ECAS), and trailer communication. Common RFC Fault Codes
Faults often appear as a code followed by a Failure Mode Identifier (FMI), such as "1A 05". Common Cause / Fix Front axle pressure sensor value too low
Often a faulty sensor on top of the Air Processing Unit or wiring issues. Number plate light open circuit Usually a blown bulb. Ensure a bulb is used; 5W bulbs can trigger "value too low" errors. Rear right position light open circuit Check the 5W bulbs in the rear right cluster. Trailer stop light short circuit Potential short in the trailer electrical spiral or plug. Tail clearance/dimension lights current high
Possible wiring short or incorrect total wattage of bulbs installed. Left parking lights short circuit
Check for water ingress or frayed wires in the left rear cluster. Pneumatic horn power supply open circuit Issue with the horn solenoid or its dedicated fuse. IVECO Stralis RFC Fault Codes Guide | PDF - Scribd
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). Step 4 – Perform a Free Regeneration Override
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.

You do not need to buy expensive diagnostic subscriptions to read IVECO Stralis RFC fault codes. Use the dashboard self-test, a $15 ELM327 adapter, or IVECO’s free web tools. The most common RFC issues involve fuel filtration (RFC_01), injector wear (RFC_12-15), or sensor plausibility (RFC_20). Repair accordingly, clear codes via battery reset, and get your Stralis back on the road.
Disclaimer: Always verify codes with your specific VIN and engine type. Fault codes are diagnostic clues, not final repair instructions. For critical systems, consult a qualified mechanic.
While Iveco uses specific proprietary protocols (K-Line and CAN-BUS), generic OBDII scanners often fail to read transmission-specific codes. You typically need Iveco-specific software (like Iveco E.A.S.Y. or Wisdom) to get the exact alphanumeric code (e.g., EDC 4A5).
However, here are the most common numerical references associated with RFC/Range Change failures on the Stralis:
| Fault Code / Reference | Likely Component | Description and Symptoms | | :--- | :--- | :--- | | P1740 / Code 15 | Splitter Solenoid Valve | Open circuit or short to ground. The ECU cannot energize the valve to switch ranges. Truck may get stuck in one gear range. | | P1741 / Code 21 | Range Position Sensor | Signal implausible. The sensor reports the gearbox is in High range when the ECU requested Low, or vice versa. | | P1730 | Transmission Actuator | Mechanical failure. The pneumatic actuator is stuck or leaking. You may hear hissing air from the gearbox area. | | P1725 | J-Gate / Selector Lever | Fault in the gear selector signal. The truck does not know if you want Drive, Neutral, or Reverse. | | P0730 | Incorrect Gear Ratio | A generic code often triggered when the splitter fails to engage, causing a slip or mismatch between engine RPM and wheel speed. | | EDC 615 | Clutch Position Sensor | Often linked to RFC faults because if the clutch doesn't open fully, the range change cannot occur. | | Code 43 | Pressure Switch | Low air pressure supply to the gearbox splitter unit. Check air tanks and dryer. |
