Hi! I'm new for this forum. I have Elantra HD 2007 year, 2.0, MT.



I've bought ELM327 and it does not connect to ECU. ELM327 is working good with other cars.

After a good search I found that some Hyundais does not have a ground on pin# 5 in OBD connector. For others you should put a K-line from ECU to pin#2 in OBD connector.



Does any body have experience with it?



My ECU part number is 39140-23260.



Does any body have pinout for it. And pinout for diagnostic connector in engine bay?



Thank you!

 

My car is a different model year, but my generic ELM327 bluetooth dongle from eBay works just fine on my Hyundai.



Unfortunately they charge for it, but not very much money for a short subscription - Hyundai has all their manuals online at https://www.hyundaitechinfo.com/

 

Thanks, I know that site, I was free couple of years ago

I'm from Ukraine, now 20 bucks is big money here

 

I've been keeping an eye on that . . . hopefully they figure out it's time to stop shooting before a wheelbarrow of local currency buys a loaf of bread



unlike SOME countries



Edit to add: UGH! If any haven't been paying attention, here's a chart showing just how expensive $20 has become in the last month: http://globaleconomicanalysis.blogsp...laughable.html
