Airbag resister

porsche959 · 12-09-2018, 02:07 PM

Just installed a Momo steering wheel but it’s throwing the airbag light. Have two resisters but can’t figure out how to clear it.

I am getting codes: 93b4 93a8

I’ve pretty much tried out every combo but still can’t get it to work...

Anyone have any advice? Thanks

If you did this without disconnecting the battery you will get
an error that requires a BMW diagnostic setup or coding setup
to clear the error.
Once the error is registered it has to be reset with this software.

There are procedures on how to do this when going to a new
wheel that includes putting the airbag back in . My guess is you are
trying to fool the car into to thinking there is and air bag there.

This is not usually a question for the stereo board.

Where did you get the procedure for installing whatever you are installing?

From the second to last picture just a comment
that the quick dissonnects for the two resistor are
not insulated with tape in the picture. I assume
you are doing this before tucking them away.
