Airbag light is on with the code 93DB - step up converter defective. When I took it to a garage they told me that it was the left b pillar airbag module that was causing the issue as their machine was saying it wasn't working & there was a leak that was causing the module to get wet. I've got the correct airbag module for it but found out that all airbag modules were able to communicate at times when the car was plugged in. In the end, the airbag modules didn't get swapped around as I think it may be the main module that is the issue as at times it wasn't able to see either of the b pillar airbag modules. Has anyone had or known of anything similar & what it was in the end?
