LELink Bluetooth Low Energy BLE OBD-II OBD2 Car Diagnostic Tool for iPhone/iPod/iPad and Android. New: Configurable Auto On/Off

This worked exactly as advertised. For what the dealer said couldn't be done, we got done for $40. This and SpyLeaf to fix the door lock settings on my 23 Leaf. There was some issues with setup, I had to turn on the bluetooth on the app on the iPhone settings, which Tech support helped be with. They were very responsive to support the app that connected with their product. I am still waiting for the app folks to help me, but it won't be needed because of the fast and expert advice given by the hardware guys. Depending on your vehicle and software, you could control door locks, beepers, lights, and other timers, without the expense of the dealer. As well as studying your engine codes, battery health and the like. Great product.

What an amazing tool. In fact, I leave it plugged in at all times, even in my EV as it draws so little power. The real-time reporting is awesome. Combined with the LEAFspy app, it keeps me in the know while charging or driving. It just plugs in and you forget it. I highly recommend it.Photos are from LEAFspy app based on real-time data from device.

Works as expected; no issues.

I had bought a cheaper black Friencity Bluetooth OBD2 diagnostic interface from Amazon and had nothing but trouble trying to make it connect to my phone or to my car. I decided to spend a few more dollars and get a better one that was mentioned in a YouTube video. Plugged it in and it worked connecting to my phone immediately. Big plus. I like the fact that it has a clear cover and is small, so no matter which way the USB 2 port on your car faces you can see the lights working. On the previous one I returned, the lights were turned away from me, facing the brake pedal so I had to use my phone's camera to even see if it was turned on. I would highly recommend this product. I had absolutely no problems with it on a Nissan Leaf running Leaf spy.

Update: 2-21-17. Upgraded to 4 stars. Company reached out and sent me a new device before receiving mine back. We're on day 1 but its as advertised. Will update if changes.Ok.. i tried reaching out to them before writing a review. Mine stopped working after a couple of weeks.. Worked great up until it stopped connecting. I have a bad 02 sensor and was monitoring the readings to catch it throwing a code.. One day the phone wouldn't connect.. I fiddled with it.. left it unplugged for a while and then plugged back in.. It would connect but got harder and harder to connect.. Finally it stopped.. The red light on it got dimmer and pulsed a little like it has a voltage issue.. Up until then it was great, reset codes.. built customer display.. bought dashcmd , don't get it .. its not compatible and that was a waste of money.. A lot of them are not compatible with this module.

I've been using this for nine months so far, and it works great!I use this on an iPhone. You do need to purchase software for this, but it should work with many OBD2 apps. I use OBD Fusion ($10), and it works nicely, letting you customize your app dashboard, read and clear codes, etc. This app has a fast-response mode, which drains your phone battery faster, but gives you even faster than the standard speed. (Standard is probably one update per second.) This device has no problem keeping up.This device is low-profile, and of course doesn't have any wires to plug in -- you just plug in the device itself, and it gets power from the OBD2 port. (All cars in the U.S. since I think 1996 have to have standard OBD2 ports.)I use this on a 1996 Lincoln Mark VIII and a 2001 Jeep Grand Cherokee. No problems switching between vehicles.My only disappointment is that I was hoping there was a power switch, or that it would automatically shut off after shutting off the car, so I could leave it plugged in without draining the battery. But it stays on the whole time -- you can't connect when the key isn't in the "run" position, but it still gets at least enough power to keep flashing the LEDs. I've accidentally left it plugged in a couple times, and it's not enough draw to kill the battery overnight, but I still wouldn't want to leave it plugged in all the time. (Obviously, this was not a big enough problem for me to lower my rating.)Oh, and speaking of the LEDs, they're easy to see when you're looking at the device, but they're not distracting for me when driving, because the OBD2 ports on both my vehicles are under the dash, so you can't see the lights at all when driving, even in your peripheral vision. I suspect most cars are like that, but if you can directly see your OBD2 port when driving, you might end up putting electrical tape or something over this to hide the lights.

Used this with the Doctor Prius app worked fine on a 2011 Prius.
