Nissan Juke Dashboard Warning Lights
Every light on your Juke’s dash explained – from a simple reminder to a stop‑now emergency.
This guide covers all factory‑fitted warnings for Nissan Juke (2010–2019, including pre‑facelift and facelift models). We’ve added rarely documented lights (glow plug, LDW, airbag, transmission) and the most detailed diagnostic steps available. Red lights demand immediate action.
Essential & additional warning lights – full breakdown
Check engine
- Issue: Emissions, sensor, ignition, or fuel system fault.

How to diagnose any dashboard light (Juke owner workflow)
- Note the colour – Red: stop asap; Amber: schedule inspection; Green/Blue: system active.
- Check owner’s manual – symbol location (if unfamiliar).
- Quick visual inspection – fluid levels (oil, coolant), tyre pressure, visible leaks.
- Use an OBD2 scanner – even for non‑engine lights, many modules store codes (ABS, airbag, etc.).
- Research the code – online forums, but cross‑reference with Juke specific TSBs.
- Perform pinpoint tests – multimeter, vacuum gauge, pressure tester as described per light.
- Clear codes & test drive – if light returns, deeper issue.
- Seek professional help – for airbag, CVT, or module related warnings.
For Juke, the most common overlooked issue is battery voltage – many warning lights (ABS, EPS, AT) can trigger due to low voltage. Always check battery health first.
Advanced diagnostic options & tools
- Consult‑III / J‑2534 pass‑thru – dealer level programming, module reflash.
- Smoke machine – EVAP and intake leak detection (common on Juke after 100k km).
- Oscilloscope – testing crank/cam sensors, wheel speed signals.
- Pressure transducer kit – fuel pressure (direct injection MR16DDT) and transmission line pressure.
- Thermal imaging camera – find overheating connectors or exhaust leaks.
