Hi everybody
I hope than you can help me, some time ago my Hyundai Santa fe 2011 was stolen, after some days I did recover it, but the main problem was without some parts, including body parts, electronic parts, etc.
After almost 2 years my SUV is complete, I bought ECU, Front crash sensors, steering driver airbag, front body and others. Right now my car is working, but the airbag light on the dashboard is still ON. I have a LAUNCH scanner and I read the airbag module and this have a permanent fault (B1684 - ACU Configuration is different). The SRSCM or ACU (Airbag control unit) was not changed, it's the original, so I can't understant the main reason of my problem.
The number part of my SRSCM is 95910-2B080, I did check that with the local dealer, and the part number is the correct for my VIN number.
Some local technicial said me than I need change the SRSCM, but the price here in my country it's over 1300USD.
Could you help me in order to solve this problem?
Thanks in advance,
Patricio

if the part # is the same and you are sure its the right module for the car, then it will need to be program to vehicle.
Yes, you can program only one time. BUT !!! If you read eeprom from airbag module before programming, you can after programing write back original virgin file and program again. And so many times.
Its very much possible that you are connect some element what your car have not before you start to repair. Understand ? Try to disconnect something and check what happen. Or maybe some sensor is not appropriate for your car, different number. In VAG vehicle that i have before. If crash sensor is not just right for my car - problems. Better check are you buy good compenents for your car, specially crash sensors !!!
Disconnect crash sensors and erase DTC-s and check what DTC-s will remain. Maybe DTC B1684 will disappear.
I think he got a used module so dunno about that writing back virgin file back to module part.. I think you will need a code to program it.

Variant coding is an alpha - numeric 4-digit code the ACU uses to determine specific equipment. To my understanding it is only required upon replacement with a brand new module. If used module was installed and this code present, means most likely incorrect part number.
It is a vin specific code and the dealer can retrieve ACU code from VIN. There is however a third party program available to do this, I cannot remember who makes it but I know the price is not worth it unless you do this type of thing quite frequently. Otherwise let the dealer do it
