MechanicBrief

Support

MechanicBrief helps you read OBD trouble codes and live data with a plain-language brief. It is not a substitute for a qualified technician.

FAQ

Pairing an ELM327 Bluetooth adapter

Turn the vehicle ignition on (engine running or accessory, as your adapter requires).
Plug the adapter into the OBD-II port and wait until it is ready (often a steady or blinking LED—check your adapter’s guide).
On iPhone, open Settings → Bluetooth and pair the adapter if iOS lists it. Some ELM327 units use a pin such as 1234 or 0000; use the pin printed for your unit.
Open MechanicBrief and connect from the app. Stay close to the adapter; Bluetooth range is short.
If the app cannot connect: forget the device in iOS Bluetooth settings, power-cycle the adapter, and try again. Not every “ELM327” clone behaves the same on iOS.

Reading codes and live data

Once connected, the app can request diagnostic trouble codes and live sensor-style data from the vehicle’s OBD interface, then present a plain-language brief. Exact availability depends on the vehicle and adapter.

Clearing codes — important caution

Clearing codes only happens after you confirm in the app. Clearing codes does not fix the underlying problem. It can turn off a warning light temporarily, erase freeze-frame data, and may affect readiness monitors used in emissions inspections. Do not clear codes to hide a safety issue. If you are unsure, leave the codes in place and see a qualified technician.

Where is my data stored?

Scans and any records you save (such as receipts or document photos) stay on your device. You may optionally use your own iCloud. See the privacy policy.

VIN decode

VIN lookup uses the free NHTSA vPIC decoder. The VIN is sent to NHTSA for that lookup.

Purchases and refunds

Purchases are handled by Apple through StoreKit / the App Store. For billing or refund questions, use Apple’s App Store purchase support. For product questions, email us.
