The RFC detects a trailer via two methods:
Instead, the Iveco Stralis utilizes a hydraulically or electromagnetically controlled fan system managed by the RFC module. This module receives input from the Engine Control Unit (ECU) regarding engine temperature, air conditioning pressure, and exhaust gas temperature. It then precisely modulates the fan speed—turning it on, off, or varying its speed—to maintain optimal operating temperatures. iveco stralis rfc fault codes
RFC (Rear Frame Computer) on an Iveco Stralis manages critical rear-vehicle functions, including external lighting, air pressure sensors for the rear axles, and brake wear indicators. The RFC detects a trailer via two methods:
Ignoring trailer-related RFC codes. Reality: An RFC-2223 (Trailer EBS fault) is often caused by a damaged trailer cable, not the truck’s RFC. air conditioning pressure
An RFC fault code typically appears as:
