Well I haven't seen one of these in awhile. This was very common on the 2005-2007 Focus. There was a message or tsb from ford on this at one time explaining to do this procedure. I have cured more than I can remember with this procedure as Ford Air Bags are very reliable and almost never need replacing unless damaged in an accident. I hope this helps.

 

I am wondering if this technique works with the E-350 as well. We have airbags lights on the focus and the motor home.

 

DO NOT follow the youtube link above it was misleading. The person who made that video didn't even have a clue what a dielectric grease is and applied it incorrectly. Regardless of your application, never apply it directly on any conductor as that defeats the whole purpose of using dielectric grease in the first place.
