Using your iPhone to diagnose your car’s check engine light

“All the do-it-yourself mechanics out there love being able to troubleshoot their own check engine light (CEL) to see what’s going on under the hood of their own cars,” Anthony Bouchard reports for iDownloadBlog.

“Typically, doing so requires an expensive OBD II scanner tool that plugs into the OBD II port underneath the dash,” Bouchard reports. “But, with an app on your iPhone and a tiny accessory that plugs into the OBD II port, you could save some money and you’ll still have access to a lot of the information the scan tool would give you. In fact, because of how advanced your iPhone is, you may even get more information than a lot of the scan tools will offer.”

Bouchard reports, “In this review, we’ll be taking a look at the LELink Bluetooth Low Energy BLE OBD-II OBD2 Car Diagnostic Tool For iPhone/iPod/iPad, which can be had for about $35 on Amazon, as well as the $9.99 OBD Fusion app, which can be had from the iOS App Store.”

MacDailyNews Take: As always, it’s amazing what iPhone and iPad can do!


  1. Just got this set up on my iPhone 6 last week to check the codes on my Toyota. I found it had a lot more functionality than just checking codes and resetting the check engine light. You can set it up to watch a lot of different variables while the car is running, and while you are driving. Be careful not to get distracted while driving!


  2. $35 dongle, $10 app.
    $20 stand alone scanner.

    “Expensive ODB II” scanner???

    I’ve been thinking of grabbing one of these dongles anyway, so not knocking it. (Just the articles author)
