Know what the light means
before the shop tells you.
A warning light means something specific. HALO reads the trouble codes behind it and explains them in plain language — what it likely means, how serious it is, and what to do next. Walk into the shop already knowing the story.
A code is
not an answer.
A basic code reader tells you “P0300 — Random/Multiple Cylinder Misfire Detected.” That’s a code, not an answer. Is it a spark plug, a coil, a vacuum leak? You end up searching the code and reading old forum threads.
HALO reads the same code and looks at it in context — your car, and the other codes that came with it. Instead of a cryptic string, you get a short summary, how serious it is, the likely causes, and what to check first.
- Plain-English cause, ranked by likelihood
- Severity and what to check first
- Works with a standard Bluetooth OBD adapterAdapter
Same code.
Real answer.
Random/Multiple Cylinder Misfire Detected
Now what?
Misfire on cylinder 3. Most likely the ignition coil or spark plug on that cylinder.
Severity: Medium · Next: check coil 3 · DIY: Moderate
The cause,
not just a code.
Trouble-code scanning
Plug a standard Bluetooth OBD adapter into your car’s diagnostic port and HALO reads your trouble codes.
Plain-language explanations
Each code comes back as a short summary you can actually read, with the likely causes listed most-likely first and the reasoning behind them — so you can judge it for yourself.
Severity at a glance
Know how urgent it is. HALO tells you whether a code is something to keep an eye on or something to deal with now.
What to do next
Clear next steps: what to check first, and whether it looks like a weekend job or a visit to the shop. Walk into any repair conversation informed.
Live engine readings
The same adapter lets HALO show live engine readings alongside your codes, so you can see how your car is running, not just what it has flagged.
Your car, fully awake
On the 2014–2023 Infiniti Q50, the plug-in HaloHub lets HALO read your car directly — gear, rpm, speed, turn signals, lights, brakes and doors. More cars are coming.
