another airbag code

High resistance codes mean that a connector was unplugged at some point, and when it was plugged in there was "high resistance" found. Ford's electrical connectors (the contacts, at least) are made of aluminum. Aluminum oxidizes over time, and does not conduct electricity as well. When you unplug and reconnect a connector, the contacts line up differently and you could have oxidized parts touching. This is the "high resistance" that the code refers to. Power is flowing but not as well as it should.

The solution is to unhook the connector the code refers to, and spray electrical contact cleaner on the contacts. Once the cleaner has dried/evaporated, hook it back up. The code should either go away or change.
