Iveco Stralis — Rfc Fault Codes

In an IVECO Stralis, RFC (Rear Frame Computer) fault codes generally relate to electrical issues in the rear section of the vehicle, including external lighting and air pressure sensors. These faults are often triggered by incorrect bulb wattages, corroded wiring, or failing sensors. Ивеко Форум Common RFC Fault Codes & Meanings

Diagnostic Code

| | Description | Severity | Common Cause | |---------------------|-----------------|--------------|------------------| | RFC 001 | DPF Soot Load Too High (Above 140%) | High – Limp mode | Frequent short trips, faulty differential pressure sensor. | | RFC 019 | Exhaust Gas Temperature Sensor 1 (Before DPF) – Plausibility Error | Medium | Sensor failure, wiring harness chafing near the turbo. | | RFC 032 | Diesel Exhaust Fluid (AdBlue) Quality Fault | Medium | Contaminated DEF, wrong fluid, crystallization in tank. | | RFC 045 | EGR Valve Position – RFC Conflict (Stuck Open/Closed) | High | Carbon buildup, failed EGR actuator, low engine compression. | | RFC 078 | Fuel Dosing Unit – Open Circuit | High – No regeneration | Broken wire at the dosing injector connector, corroded pins. | | RFC 092 | DPF Differential Pressure – Plausibility (Signal out of range) | Medium | Hoses melted or clogged with soot, sensor offset. | | RFC 113 | Engine Torque Derate Active – Forced by RFC | Info only | Consequence of other RFC faults – triggers limp mode. | | RFC 141 | Ash Accumulation – Permanent DPF Limitation | High – Replace DPF | Engine oil consumption, poor fuel quality, high mileage (>500,000 km without cleaning). | The RFC code is not a punishment; it is a cry for help
