Iveco warning lights: what each light means
In Iveco models, the documented faults light up 6 warning lights on the dashboard. The most frequent: ABS/ESP light (2 faults), airbag light (1 fault) and parking brake warning (1 fault).
Which warning lights the faults of Iveco trigger
Red ones first, and those that call for stopping. Below each warning light, the documented faults that trigger it, with their pages.
Airbag warning light on
Urgency: Garage soonRedSymbol: a seated person wearing a seat belt with a circle (the inflated airbag) in front; in some cars, the letters SRS or AIRBAG
The airbag warning light means the system has detected a fault and an airbag or seatbelt pretensioner may not deploy in a crash. Causes range from a connector under the seat to the control unit or the airbag itself.
What to do: Have it diagnosed as soon as possible and check with the VIN whether the car has any outstanding airbag recall.

- High severity: Driver's airbag warning light that does not come on when the system fails · outside the engine · Daily VI
Electric parking brake warning
Urgency: Garage soonRedSymbol: letter P inside a circle in brackets, sometimes with an exclamation mark
Cars with an electric parking brake show a warning light or message when the caliper motor, its wiring or the control unit fails. The brake may not release or may not apply.
What to do: Do not rely on the handbrake if the warning appears: park on level ground and leave the car in gear. Have the system diagnosed.

- Medium severity: Secondary parking brake cable that can break at its eyelet · outside the engine · Daily VI
ABS or ESP warning light on
Urgency: Garage soonYellow or amberSymbol: the letters ABS, usually inside a circle, in amber or orange
It indicates a fault in the anti-lock braking or stability control system: often a dirty or damaged wheel speed sensor, its wiring or the hydraulic unit. The brakes still work, but without those aids.
What to do: Drive carefully, especially in the rain, and ask for a fault code read-out. It is often fixed with a wheel sensor.

AdBlue system warning
Urgency: Garage soonYellow or amberSymbol: AdBlue system warning in the instrument cluster, yellow or orange at first, usually accompanied by a text message and, later on, a countdown in kilometres
Diesels with selective catalytic reduction (SCR) use AdBlue to cut NOx emissions. A warning with a countdown ("engine will not restart in X km") indicates a low level or a fault in the AdBlue tank, pump, heater or injector. When the countdown reaches zero, the car will not start again.
What to do: If the tank is full and the warning persists, the problem lies with the system. Go to a garage before the countdown ends and keep your receipts in case the fault is covered by a manufacturer campaign.

- Medium severity: AdBlue (SCR) system faults and a saturated particulate filter on the Euro 6 · 2.3 MultiJet engine · Daily VI
Particulate filter warning light (DPF)
Urgency: Garage soonYellow or amberSymbol: particulate filter symbol on the dashboard, normally amber; its design varies by manufacturer
On modern diesels it means the particulate filter is clogged with soot and has not been able to regenerate. It is common in cars used mostly for short town journeys, although it can also be caused by a sensor or by an injection or EGR fault.
What to do: If the handbook allows it, a 20-minute drive on a motorway at a steady speed can complete the regeneration. If the light stays on or you lose power, go to a garage.

Engine fault warning light (check engine)
Urgency: Garage soonYellow or amberSymbol: outline of an engine seen from the side, in yellow or orange
The orange engine-shaped warning light comes on when the ECU detects a fault affecting combustion or emissions. If it flashes, it usually points to misfires that can damage the catalytic converter.
What to do: If it stays on steadily, you can drive gently to a garage and ask for a fault code read-out. If it flashes or you notice a loss of power, slow down and get to a garage as soon as possible.

Frequently asked questions
Which warning lights come on most in the Iveco?
ABS/ESP light: 2 documented faults, such as rear axle ABS sensors: intermittent ABS/ESP warnings. Airbag light: 1 documented fault, such as driver's airbag warning light that does not come on when the system fails. Parking brake warning: 1 documented fault, such as secondary parking brake cable that can break at its eyelet.
Which warning light of Iveco is the most serious?
None of the warning lights with documented faults in the Iveco requires an immediate stop. The most serious fault that triggers one of them is driver's airbag warning light that does not come on when the system fails (airbag light), of high severity severity.
Which Iveco models have the most faults that trigger warning lights?
Iveco Daily VI (5 faults), Iveco Daily IV (2 faults) and Iveco Daily V (2 faults).
A warning light has come on in the Iveco: what should I do?
Find which warning light it is on this page and check its urgency. For the others, book an appointment at a garage and have them read the fault code with an OBD reader: it shows which system has failed.
