- Engine codes vs other systems
- Basic readers handle check engine codes. If you want ABS, airbag (SRS), or tire-pressure (TPMS) systems too, BlueDriver lists those.
- Subscriptions
- BlueDriver is subscription-free. Some app-based scanners keep features behind a paid plan, so check before you buy.
- Your car's year
- OBD2 is standard on US cars from 1996 on. All the picks here are built for OBD2 vehicles.
Our shortlist
Get BlueDriver for the most capable phone scanner without a subscription. FIXD is the simplest for non-car people. For a handheld that needs no phone, the ANCEL AD410 is the pick and the AD310 is the budget version. Enthusiasts should look at the OBDLink MX+, and the Veepeak is the cheapest Bluetooth option.
Frequently asked questions
Will an OBD2 scanner turn off the check engine light?
Many can clear codes (the ANCEL AD310 lists read and clear), but the light will come back if the underlying problem isn't fixed. Read the code first and fix the cause.
Does my car have an OBD2 port?
Cars sold in the US from 1996 on use OBD2. The port is usually under the dashboard near the steering column.
