Kia Optima Air Bag ACU Code B1762
I had a 2013 KIA Optima come in from a body shop to repair
the air bag after collision.
I realize that the vehicle info says Sorento but I.A.T.N.
does not list Optima in 2013.
I pulled the trouble code B1762 ACU coding error. B1762
GDS B1762 ACU Code
All the body shop would tell me was it had all new air bag
Using KIA GDS I went into ACU coding function and it
requested a four digit code. I called local dealer to get
the code TFA4 but was also able to get the code using the
automatic procedure with GDS connected to internet as well.
Kia ACU Code Function 6
The ACU Code function failed. I double check the code and it
failed again. KIa ACU Code Errorr
After I made a call to Joey at A&E tools and getting an
education how this system works I was able to get it fixed.
Want I learned was that if you are going to replace the air
bag module on a newer Kia/Hyundai you will need to repair
all faults in system before installing new module. You want
to make sure that all faults in the old module except crash
data are corrected first.
You can also retrieve the ACU code from the old module and
use it to code the new module as long as the part # is the
The ACU code is the as built code for air bag system.
The airbag module will NOT code if any faults are present,
but the airbag module will NOT set faults until coded.
In my case the body shop had thrown away the old module and
the car had 600 miles on it so every part looked new and I
was told had been replaced.
You will either have to test each part until you find a
fault (ohm out seat belt & buckles, etc..) or install the
new module in another vehicle with same options.
I went to local dealer and they had four of same model. I
check the V.I.N.s on all four and they had the same ACU
After asking very nicely and explaining my situation. I
installed my new module in one of their new cars and the ACU
code worked fine. I then took my coded module back to shop
and installed in the body shop car.
It now would list the current faults for driver side belt
and buckle. I replace both parts and issue was solved.
