Iveco Stralis Rfc Fault Codes Best [Real]
RFC fault codes consist of two parts:
Rear suspension will not raise or lower, truck rides unevenly, or suspension lowers automatically overnight. Common Causes:
| | Action | |--------------|-------------| | Every 90,000 km | Replace differential pressure sensor hoses (they become brittle). | | Every 150,000 km | Clean EGR valve and cooler (prevents RFC 045). | | Every 200,000 km | Perform forced DPF regeneration and check ash load via diagnostic tool. | | Every 450,000 km | Professional DPF cleaning (off-truck thermal or ultrasonic cleaning). | | Annually | Test DEF quality and inspect dosing injector for leakage. |
| 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. | iveco stralis rfc fault codes
Bad intelligent device or component (internal RFC internal hardware failure).
: Left/Right rear indicator circuit fault. Usually caused by a blown bulb or a corroded light cluster socket.
Positive circuit fault for right-side low beam/dipped lighting. Right Side & Rear Direction Lights RFC fault codes consist of two parts: Rear
: Controls tail lights, brake lights, indicators, fog lamps, and reverse lights.
A secondary number that describes the type of electrical failure, such as a short circuit or an open circuit. Common Iveco Stralis RFC Fault Codes
If you have a fault accompanied by a zero reading on your air gauge, the air pressure sensor on top of the Air Processing Unit (APU) is likely failing. This unit is located in the middle of the chassis and has a large filter cartridge. 4. Resetting the Fault | | Every 200,000 km | Perform forced
The Iveco Stralis is not just a mechanical machine; it's a network of electronic computers (often called ECUs) that control every function, from the engine to the lights. The stands for Rear Frame Computer .
The wiring looms running along the frame rails of the Stralis are exposed to road salt, water spray, and constant vibration.
The Rear Frame Computer is a localized Electronic Control Unit (ECU) positioned at the rear of the truck chassis. It connects to the primary engine ECU and dashboard via the vehicle’s CAN-bus (Controller Area Network) lines.
The RFC relies on clean grounding studs welded to the vehicle chassis. Rust, paint overspray, or road grime at these ground points will increase electrical resistance, throwing multiple random light faults simultaneously. Incorrect Bulb Wattage
Instead of routing dozens of individual wires from the dashboard to the tail lights and axles, Iveco utilizes the RFC to multiplex these signals. The dashboard sends a digital command over the CAN-bus, and the RFC executes the power delivery locally. Primary Functions Managed by the RFC:
