Hyundai variant coding
Have a 2018 Hyundai Elantra came in and replaced air bag module due to water intrusion. No communication with old module, installed new tried to do variant coding with autel. It auto fills in coding which works most of the time but fails to code.
I have had a few in the past that it auto filled and the coding was wrong that autel used I was able to plug up old module and get correct coding, but since I can communicate with old one I can’t.
I understand if there is problems on airbag system it won’t code also I just want to make sure I have correct coding first. I used to able able to call my Hyundai parts department and they would give me the coding, but that person doesn’t work there anymore and nobody there seems to know how to look it up.
I paid for subscription to Hyundai service and can’t find it on there. I know if u pull a vin stat inquiry on Hyundai, it will give it to u if u have access. I watched my friend do it at Hyundai dealer before.
Is there any where else I can get coding even if I have to pay? I just want to make sure I have right coding before I go any further, thanks.
John Create an Hyundai account and pay your money for the a subscription and once you put the VIN in there will be information on how to get the variant coding fir the air bag module
Sure, I paid $40, I got “no code”. Hyundai and Kia used to be great, free. Now what POS’s
… Maybe hit ENTER every once in a while and make a paragraph , while ya are at it. … Dan H. … Hobbs … South Texas … My 71 year old eyes don't like his style … and I told him so. … Another dog pile on Dan day it looks like … Dan H.
He'd have to put a period at the end of a sentence before pressing the enter key. It makes it so much easier to read if the post is broken up with paragraphs. What your detractors don't understand is that a post like this turns away a lot of the very people you are hoping will help you. A hard to read post is easy to ignore.
Dan, glad to see someone, other than myself getting “down” remarks from the crowd. I thought I was the only one waiting to get voted off the island!
… Two or three members agreed with me by the looks of the tally… I'd get booted offa here if I typed what I really thought about his style of posting… I am entitled to my opinion in that regard… It WAS more of a request to be considerate ( looks like it fell on a lot of deaf ears)… I'll just skip posts like that from now on and save my fingertips. … Dan H. …Hobbs … South Texas …
Hello John, Same kind of issue here today. Santa Fe 2020 for an accident. Brand new module try to code with a ms909 pull out the code automatically. Error came when they try to reprogram . Call a guy they have dealer access , the ACU/srs code is the same the autel pull me out. Buy a j2534 access and they didnt have the possibility to make the coding. I'm in an impass. Finally need to find answer…
Jean-philip the issue with your Hyundai is there is a issue with the SRS system something is deployed/unplugged ect That the body shop missed. The coding will be rejected if there is a problem. Once everything is fixed the ACU coding will be accepted. With the factory tool you can see the reason why it was rejected. The only other tool that i believe that does that is the Gscan. Hth
I buy the online j2534 diagnostic software , no other code only the B1762 for the variant coding . No coding in the ecu detail and no able to change it with the j2534 Hyundai access.
Hyundai and KIA J-2534 software is only for ECM & TCM, the R@R Diagnostic software is not compliant with the R2R laws and is an absolute waste of money with zero way to contact anyone about it. Contact your bank card and dispute the charge, state that the software did not perform as advertised and maybe you will get a refund.
Look at the SRS data for a deployment loop with an out of spec ohms reading. You'll most likely find one. repair that, then attempt coding again.
It’s probably the correct code. If there is a fault in the system it will not accept the coding. Check all seatbelts and pre-tensioner‘s to verify they have not deployed. If you do not see anything wrong then purchase the Hyundai RTR software and click on the DTC status button. It will tell you why it’s not accepting the coding.
Thank u Igor I will try that in the morning I believe that is the correct code for this car autel said aus3 I thought it began with a g I did one several months ago on 18 elantra it gave me the wrong code
Just as others have stated. If there is any issue in the SRS system, the new module will not accept the code. One of my field techs ran into this earlier in the week. Turns out that the collision shop did not replace enough seat belt pretensioners. Once replaced, no issues. It is the OEMs way of making sure that you will not have a sudden and unexpected deployment due to a damaged component…
As a follow-up to my earlier message, if you have access to the original module you can install it and read codes. You must repair any codes that are active aside from the deployment commanded code. Then put your new module in and attempt to do the coding.

Bruce, they have been not accepting new sign-ups for about a year.
