Car Check β Community App Review
Version: 0.1.1
Car Check reads what the check-engine light is on for, through a Bluetooth OBD-II adapter, and says it in words.
The first line says whether the light is on. Under it, each trouble code with its meaning and what kind it is: stored (confirmed, and lighting the lamp), pending (seen once, not yet confirmed), or permanent (kept by the car until it has seen for itself that the fault is gone).
Clearing the codes is a row you tap twice, and it warns first that the emissions readiness goes with them. If the car refuses, and most do with the engine running, it says so and why, rather than leaving the old codes on the screen as though nothing had been asked.
Live data shows engine speed, coolant, fuel trims, load and whatever else the car offers, once a second, with the readiness monitors after them. The freeze frame shows the engine as it was when the first stored code was set. Where the car reports it, there is the VIN and its calibrations. Metric or US units.
It needs a classic Bluetooth ELM327 adapter, the small plug-in kind sold under a dozen names, paired in the phoneβs Bluetooth settings first (most take 1234). Low Energy and Wi-Fi adapters are not supported. It reads the standard OBD-II codes and readings; what makers keep for their own dealer tools, such as airbags and ABS, is out of its reach.
No account, no history, no network. It remembers which adapter you chose and your units, and nothing else.
Built on AndrOBD by fr3ts0n, whose protocol library it carries: the ELM327 conversation, the OBD services, and what every reading and code means.
Which adapters have you had work, and which have refused to talk?
