## What is CarIQ?

Check engine light on? CarIQ tells you exactly what your car's OBD-II code means — in plain English, right on your phone.

Search or browse a library of 900+ diagnostic trouble codes covering every generic OBD-II code plus manufacturer-specific codes for dozens of makes. Pick your vehicle once and CarIQ surfaces the codes that actually apply to it.

FREE, ALWAYS:
• Full code search across the entire catalog
• Code title, category, and urgency at a glance
• Plain-language description of what the code means
• Save favorites and keep a history of recently viewed codes

UNLOCK WITH OBD EXPERT PRO:
• Possible causes behind the code
• Typical symptoms to watch for
• Estimated repair cost ranges
• On-device AI explanations powered by Apple Intelligence, tailored to the specific code

No obligation to guess, no waiting for a shop appointment just to find out what a code means. CarIQ helps you walk into the conversation informed — whether you're doing your own wrenching or deciding if it's worth a trip to the mechanic.

Everything runs on your device. AI explanations use Apple Intelligence on-device processing — nothing is sent to a server.

CarIQ is not a replacement for a certified mechanic's diagnosis. Repair cost estimates are general guidance, not a quote.
