Frequently Asked Questions
Q: Is this ELM327 OBD2 scanner compatible with iPhones or iOS devices?
A: No. This Bluetooth ELM327 V2.1 adapter is designed for Android phones, Android tablets, and Windows XP/7 (32-bit) computers only. It is not compatible with Apple iOS devices such as iPhones or iPads.
Q: What year vehicles does the ELM327 V2.1 OBD2 scanner support?
A: This V2.1 scanner is recommended for vehicles manufactured in 2010 or later that are OBD2-compliant. Most cars, trucks, and SUVs sold in the US after 1996 use the OBD2 standard, but the V2.1 firmware is optimized for newer models.
Q: Do I need an app to use this OBD2 Bluetooth scanner?
A: Yes, you will need a compatible OBD2 app on your Android device (such as Torque, OBD Auto Doctor, or similar free/paid apps available on the Google Play Store). The adapter itself does not include a dedicated app but works with most popular third-party OBD2 applications.
Q: Does the scanner need its own batteries?
A: No batteries are required. The ELM327 adapter draws power directly from your vehicle's OBD2 port as soon as it is plugged in.
Q: Can this scanner clear the check engine light?
A: Yes. Once you've read and reviewed the Diagnostic Trouble Codes (DTCs) using a compatible app, you can clear the codes — which will turn off the check engine light — directly through the app interface.
