I just received a KW902 from amazon. I tested the resistance and it was 20 ohms. I'm glad I found this thread before plugging it in! Is it worth removing the resistor or should i return it to amazon in hopes of getting a good one next?

Update:

I flicked off the resistor and the unit works just fine now. I still ordered an Lelink so I can keep it plugged in all the time with less battery drain.

Turbo3 posted to Amazon, as did I, warning people about the resistor issue. You would think the seller or Konwei might followup on that and fix the issue. Pretty disappointing that you just bought one that's still defective...

Think Turbo3 will have to removed them from his approved list for Leaf Spy.

I just got one too. Measures 20 ohms. What to do?

Just flick the resistor off with your finger nail. There's some pics early on in this thread. I ended up contacting amazon about the bad unit before I removed the resistor and they refunded my money and let me keep the unit. Now i have a working KW-902 that cost me nothing but my time.

I recently bought a Konnwei based on the recommendation of the LeafSpy app, and I'm trying to determine if it is defective. I don't see a resistor as indicated in the original image. Here is a picture of my adapter. Image

When I measure the resistance it appears to be 27kohm which seems like it would be more than 120ohm, but I'm not confident enough in my EE skills to be sure.

I'm I correct in thinking it is safe to use?

Sorry, I just saw that someone up thread had mentioned that without the resistor he was getting a read of 27kohm. I plugged it into my Leaf and it seemed to work. I was getting data, and the car didn't malfunction. :D

It seems the problem still exists , just received a Konnwei from Amazon based on all the reco and review ( new LEAF owner didn't know of this forum) .
Put in the car it gave those T.M error and I-Key error .
Stumbled on this forum while searching the net . Same issue , measure the resistance on pin 6 - 14 , it's 20 ohm .
So it seems they have not corrected the issue and still shipping defective KW-902.

I ordered KW-902 from Ebay 7. july and received it a while ago. It's the new type. The resistor has clearly been reworked as there is a lot of flux around it. My measurement of it's value is 118 ohm. The device works very well with Leaf Spy. Happy Leaf is rather slow, sometimes works and sometimes not. I think it's just that Happy Leaf is not as well programmed as Leaf Spy.

I bought the konwei adapter several months ago. I noticed it freaked out my Odyssey when I connected it (tpms/low tire pressure/airbag/CEL all illuminated) I didn't think anything of it at the time other than the Honda must not like aftermarket obd II Bluetooth adapters for some reason.
I connected it to my Leaf and had similar problems, weird lights on the dash, junk data/no data coming back. I went to the play store to read the list of approved adapters and saw the warning to not use the konwei adapter. It didn't do anything to my car, but it pisses me off that I spent money on the adapter and it's basically junk for anything with a CAN bus (I guess I can open it and remove the resistor) but I've already purchased the LELink and it's been working just fine for me.
