E85 Air bag warning light

[Paul345]

Hi all, just looking for some advice. My z4 e85 3.0si just popped on the airbag light. Scaned and came up with code 93b2 battery terminal fault. Checked all terminals and wiring at the battery everything good. Could anyone shed some light on what could be the problem. Thanks in advance

This refers to the pyro connection at the battery not just the battery positive connection. The pyro connection is part of the positive terminal and can work it's way loose causing the airbag light to light and set a code for it
Ensure the lead that enters the pyro unit is fully tapped home and making a good connection. Clear codes and cycle ignition to see if that resolved the issue.

Thanks for the reply. Will check all connections again and hopefully it will resolve the problem.

Hi. I just had this pop up tonight on my E86.
Did you get any further with fixing/finding your fault?

I've had this on my E85; the issue wasn't the warning light, it's that 99% of code readers cannot detect nor reset this code; I include Carly in that list. I had to use my Delphi (a knock-off version), which immediately found the open circuit code and reset it. All of the suggestions of battery off, ignition switch, etc, etc, were absolutely useless.
