I have a 2006 mustang that I recently got into an accident. Both airbags deployed. Now I can't start my car. It says schedule charging system, but the battery is charged. It doesn't even try to turn over. I replaced both airbags then tried replacing the RCM with one from a 2007, but same thing, it doesn't try to turn over and says check charging system. I was told I need to get my RCM reprogrammed. Is that true? I've never had to do this before, so I'm in uncharted waters for me.
