I tried to remove the panel under my steering wheel to fit an ODBII bluetooth transmitter. However there is an indentation but no removable cover (see photo). Am I looking in the wrong place? Help please !! Attachments:

You shouldn't need to remove any panel. Stick your head further underneath and look directly up to see the port

Thanks I found it however I am still having problems. The OBD2 sensor connects to Bluetooth on my phone but when I try to connect it to Leaf Spy it says something like OBD read error. I have lots of times but no result. I also tried another phone. Any ideas would be greatly appreciated.

Is your car on or charging when you use it? It has to be.

I am still having problems. There are many issues with the cheap OBDII dongles out there. Known good ones are so expensive compared to the cheaper ones, that people (like at least) try the cheap ones. Alas, almost none of the cheaper ones has an actual ELM327 chip; they are emulated in a tiny cheap microprocessor, so the whole dongle costs less than the genuine chip. To fit all the rarely used features into the cheapest chips is impossible, so they leave things out. There are supposed to be commands to tell the software what level of commands is handled, but they lie about that too. So it's hit and miss. One known-good cheap one was the Konnwei KW902. I found one of these in my leaf after I bought it second hand. Before I posted it back to the original owner, I did a little testing; it worked well (not surprisingly; LeafSpy is what it was bought for). Most unfortunately, there was a bad batch of these, with a 20 Ω resistor instead of a 120 Ω resistor! It actually killed the CAN bus in cars, causing all sorts of mischief. I can't imagine how this got through even cheap Chinese testing, but it seems that they did, in large numbers. If you end up with one of these, the fix is actually quite easy, if and only if you have access to a replacement part (costs a fraction of a cent, but you can't buy one at Jaycar), and appropriate equipment and experience. There is a Konnwei KW903 that is one of the LE (low energy) type. I have one of these, and it also works well. But there is a wrinkle in that there are different models available, and I don't recall the details. However, I posted about my trials and the exact model I bought in this thread. Edit: I'm still confused as to what the power button is supposed to do, exactly. If you're charging or "on" (press the start button twice with no foot on brake), then you don't seem to need it, though occasionally it still does, perhaps because I used it last time in error and actually turned it off. I'm not using an extension cable, so I can't see the LEDs. If anyone can educate me on exactly how that works, I'd be most grateful. The dongles have "always on" 12 V there, so it seems to me that it should "just work", but I suppose you sometimes want to make sure it's off (without unplugging it; the OBD sockets are allegedly not designed for frequent plugging and unplugging). |

You need one which supports obd protocol version 1.5
Most obd2 these days work with 2.0+ only
Lelink is recommended as per leafspy.

From LeafSpy: Due to a recent cost reduction (and feature reduction) many of the cheap ELM327 OBDII Bluetooth adapters from Asia no longer work with the Leaf and report themselves to be version 2.1. The previously recommended Bluetooth Konnwei KW902 OBDII adapter is also no longer recommended as a batch of defective ones have made their way into the market. These will basically short out your Leaf's CAN bus (or any CAN bus they are plugged into). But when removed do not seem to cause any lasting damage.
With the release of version 0.39.97 LeafSpy Pro now supports two Bluetooth 4.x LE approved adapters. The recommended one is the LELink available from Amazon. Bluetooth 4.x LE has the advantage of not needing to be paired and lower power from both the Android device and the Leaf. The LELink is highly recommended and also works with the iOS version of LeafSpy Pro.

Is your car on or charging when you use it? It has to be. Yes, I've tried connecting when charging or just if its on. I am starting to think this OBD unit might be a cheapie or knock off. Could you recommend one and where to get it. There are lots on EBay but they all look like the one that I have. |
