Open circuit, short circuit, or low value detected.

| | FMI | Description / Meaning | Diagnosis & Fix | | :--- | :--- | :--- | :--- | | 06 | 06 | General electrical error. | Check for failed sensors or broken wiring. | | 09 | 01 | Air pressure sensor signal low. | Often caused by a faulty sensor on the Air Processing Unit (APU). | | 09 | 00 | Front axle air pressure data issue. | Check the air suspension system and associated wiring. | | 0A | 01 | Short circuit to battery or positive voltage anomaly. | Inspect wiring insulation for chafing against the chassis. | | 16 | 05 | Open circuit in a rear lighting circuit. | Begin by inspecting rear light bulbs and sockets. | | 1A | 05 | Number plate light open circuit. | Fix: Ensure the number plate bulb is the correct 10W specification. | | 1B | 05 | Rear right position light open circuit. | Fix: Inspect the tail light. Requires a 2x5W (dual-filament) bulb. | | 1B | 12 | Power supply voltage anomaly for the rear right light. | Check for a faulty bulb or short in the socket. | | 1D | 05 | General open circuit or current drop in rear system. | Check all rear lights, including clearance and parking lights. | | 1E | 12 | Tail clearance light value too high (output undercurrent). | Fix: Check for corroded bulb holders or incorrectly low-wattage bulbs. | | 1F | 12 | Left parking lights short circuit. | Fix: Inspect the parking light harness for exposed wires creating a short. |

| | SPN / OBD Equivalent | Description | Common Fix | |----------------|--------------------------|----------------|----------------| | RFC 102 | SPN 3242 | Diesel Exhaust Fluid (AdBlue) quality poor – causing regeneration inhibit | Drain and replace AdBlue; reset system | | RFC 153 | SPN 3691 | RFC differential pressure sensor – circuit low voltage | Check wiring harness for chafing; replace sensor | | RFC 157 | SPN 3691 FMI 3 | RFC pressure sensor – voltage above normal | Short to power – inspect sensor connector pins | | RFC 281 | SPN 4364 | RFC fuel injector (7th injector) – open circuit | Test injector resistance (should be ~0.5–2 ohms); replace if open | | RFC 296 | SPN 4364 FMI 7 | Regeneration fuel delivery – mechanical system failure | Check for clogged line between fuel filter and RFC injector | | RFC 304 | SPN 3511 | DPF soot load too high – regeneration prevented by RFC | Forced stationary regeneration via dash switch or diagnostic tool | | RFC 412 | SPN 3242 FMI 18 | RFC temperature sensor – implausible signal (exhaust temp sensor) | Replace exhaust gas temperature sensor (EGTS) | | RFC 487 | SPN 4364 FMI 5 | RFC injector driver – current below normal (open load) | Check relay/fuse for RFC pump; test injector coil | | RFC 523 | SPN 3691 FMI 13 | RFC differential pressure – calibration needed | Perform DPF differential pressure zeroing calibration (free via dashboard sequence: reset + brake pedal) | | RFC 601 | SPN 3242 FMI 16 | Regeneration inhibited due to active DPF differential pressure derate | Perform DPF ash cleaning service or forced regen | iveco stralis rfc fault codes free

The primary peripheral control units are the and the RFC (Rear Frame Computer) . The FFC is responsible for the vehicle's front lights, sensors, and some under-hood components. Conversely, the RFC is the master controller for the entire rear electrical system of the tractor unit, including:

Short circuit or open circuit on the right rear marker/running light.

The RFC is sensitive to bulb wattage. Replacing a 10W bulb with a 5W bulb can trigger a persistent RFC error even if the light works. Inspect the RFC Module:
