Minor RFC faults (like an open circuit from a changed bulb) will move to "Inactive" status automatically once fixed. You can clear these from the dashboard memory. However, if an RFC code returns instantly upon clearing, do not ignore it. Continuous short circuits can overheat the internal drivers of the RFC module, turning a simple wiring fix into an expensive module replacement. To help narrow down your diagnostic search, please provide: The showing on your dashboard.

The FFC (Front Frame Computer) manages the electrical consumers on the front of the truck (e.g., headlights, front fog lights) and is located under the cab. The RFC (Rear Frame Computer) manages the rear electrical consumers and is located on the chassis toward the back. However, if an RFC code returns instantly upon

In the Iveco Stralis electrical architecture, the vehicle relies on centralized electronic control units (ECUs) to manage power distribution. The Rear Frame Computer (RFC) is specifically responsible for monitoring and controlling the electrical components at the back of the cab and along the chassis. Your RFC handles:
