## What is Athena OBD?

Why is the check engine light on? Will the car pass its emissions test? Athena OBD answers in plain English.

Athena OBD talks to your car through a small Bluetooth adapter that plugs into the OBD2 port under the dashboard. It works with every US car from 2008 on and most from 1996; many Fords, GMs and Chryslers from before 2008 use older wiring the adapter doesn't speak, so check yours first. The Athena OBD adapter is made and tested for it; other Bluetooth LE ELM327 adapters may work but aren't supported.

FREE
• Checks that your adapter and car work together
• Reads the engine and gearbox trouble codes, with what each one means
• A general guide to how urgent each kind of fault usually is

UNLOCK ALL FEATURES (one purchase, no subscription)
• Will I pass the emissions test? Checked against your state's rules for your car's model year: the check engine light, stored codes and the car's own self-tests
• Reset codes after a repair (they come back if the problem isn't fixed, and the car needs a few days of normal driving before an emissions test)
• Pending and permanent codes, and the freeze frame: what the engine was doing when a code was stored
• Live data: engine RPM, road speed, coolant temperature, battery voltage, fuel trims and more, as gauges on dashboard pages you arrange and graphs, recorded to a spreadsheet and played back
• Trip and fuel economy, 0-60 and quarter-mile timers
• The car's self-test results and its engine software IDs

Saved reports stay on your phone, so you can show them at the parts store or the workshop without the adapter.

GOOD TO KNOW
• Generic OBD2 reaches the engine and gearbox. Airbag, ABS and body faults need a tool for your car's make.
• Athena OBD gives general guidance, not a diagnosis. When in doubt, have a mechanic look.
• Unplug the adapter when you're done: most cars power the OBD port all the time, so a plugged-in adapter slowly drains the battery.
