🛠️ Required diagnostic data – Fiat Qubo specific
- Multiecuscan (with ELM327 or KKL) – read ABS, airbag, engine, EPAS, body computer (NFR).
- OBD2 generic – powertrain codes only, limited for chassis systems.
- Common DTCs Qubo: P0401 (EGR flow), P0670 (glow control), U1700 (CAN line), C1210 (ESP), B1000 (airbag).
- Fuse locations: engine bay (ABS, fan), passenger footwell (NFR – airbag, dash, body), glovebox (radio).
- Ground points: G944 near battery, G105 left strut tower – corrosion causes intermittent lights.
Many warning lights need ECU reset after repair – 24car-repair.com supports original Fiat procedures.
📌 Fiat Qubo warning light – advanced workshop notes
Critical fuse locations
- 🔹 Engine bay fusebox: F13 (ABS), F09 (glow plug), F15 (radiator fan)
- 🔹 Passenger footwell (NFR): F31 (airbag), F36 (body computer), F38 (dashboard)
- 🔹 Battery maxi fuses: 70A (EPS), 60A (ABS pump)
Diesel vs petrol specifics
