Iveco fault codes
Updated: 2026-11-14
The reference covers 556 codes from the factory tables of Iveco — the full list by system is below, stop-now codes first.
Iveco codes: what to know
Iveco in the free tables: 556 codes under J1939, almost none of them with a standard component name, so the name comes from the factory entry. Of the makes with standard SPN codes, Iveco has the most codes that mean stop: 1 codes on the page, listed first. The dealer entries are separate: 167 codes, most often fuel and exhaust.
Start with these codes:
- SPN 139532Body control bus CAN fault
- SPN 15734AdBlue (DEF) temperature in pump module out of range
- SPN 15735AdBlue (DEF) temperature in tank out of range
- SPN 15739Reversing valve
- SPN 15747AdBlue (DEF) temperature not plausible during commissioning
Codes that mean stop now
- SPN 131130Oil temperature too high
other — 58 codes

How to read a code
A code has two halves. SPN is what is actually at fault — the sensor, component, or parameter. FMI is what is wrong with it — value out of range, open circuit, short circuit, invalid data. So “SPN 100” alone is not a diagnosis yet, but “100/1” already tells you oil pressure has dropped below normal.
If there are several codes at once
That is almost always how it goes: one fault drags five or six codes behind it. An empty AdBlue tank first throws a level error, then interrupted dosing, then a NOx excess and a torque derate. Fix the root cause and the rest clear on their own. Paste the whole list — we will show which code is the root cause.
