Frequently Asked Questions

Q: Is this WiFi ELM327 OBD2 scanner compatible with my iPhone?

A: Yes! Unlike Bluetooth OBD2 adapters that are restricted on iOS, this WiFi ELM327 V1.5 scanner connects via WiFi, making it fully compatible with iPhone and iPad running iOS. Simply download a compatible OBD app (such as Car Scanner ELM OBD2 or OBD Fusion), connect to the "WiFiOBD" network within the app, and you're ready to scan.

Q: Which vehicles are compatible with this OBD2 scanner?

A: This scanner is compatible with all OBD2-compliant vehicles, which includes most cars and light trucks sold in the USA from 1996 onwards. It supports 9 OBD2 protocols covering the vast majority of domestic, European, and Asian vehicles. Simply locate the OBD2 port (usually found under the dashboard on the driver's side) and plug in the adapter.

Q: Can I use this scanner to turn off the Check Engine light?

A: Yes. Once you've read the diagnostic trouble codes (DTCs) and addressed the underlying issue, you can use a compatible OBD app with this scanner to clear the codes and reset the MIL (Malfunction Indicator Lamp), commonly known as the Check Engine light.

Q: Does this OBD2 adapter drain my car battery when left plugged in?

A: The adapter draws only 45 mA in standby mode, which is very minimal. However, for longer periods of vehicle inactivity, it is good practice to unplug the scanner to ensure zero unnecessary battery drain.
