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:

: You can sometimes clear "ghost faults" by performing a battery reset. Disconnect the positive battery cable for roughly one minute before reconnecting.

The RFC system is responsible for:

Imagine your Stralis shows and a pending RFC code. Here’s how to diagnose without spending a cent.

When reading your RFC codes, the FMI number tells you exactly how the circuit is failing. Typical Root Cause Data valid but above normal operating range Over-voltage or sensor calibration lost FMI 03 Voltage above normal, or shorted to high source Broken ground wire or short circuit to 24V FMI 04 Voltage below normal, or shorted to low source Short circuit to the chassis frame FMI 05 Current below normal, or open circuit Blown bulb, blown fuse, or severed wire Summary: When to Reset vs. When to Repair Your RFC handles: To give you more specific

Diagnosing and fixing the physical problem is only half the battle. Fortunately, most modern Iveco Stralis systems are designed to update automatically. Once you replace a corroded bulb, repair a pinched wire, or dry out a wet trailer plug, the RFC's anomaly counter will recognize that the fault is no longer "Active".

Ensure the ground wire from the rear lighting frame to the chassis is clean and tight.
