Question
Dennis, I have the blinking airbag syndrome on my ranger. At the same time that this started, the "off" lamp quit illuminating for pass side airbag(it is off to protect grand kids and animals from the thing). I have read other posts that suggest pass side short and high resistance to RCM bracket (flash code 4-7). If a new lamp does not fix it, I do need location of rcm bracket. I am a highly qualified electronics technician, 25 years in automotive engineering, will share what I find. I troubleshot the "excessive EGR" problem using basic techniques. The sensor is located too close to the engine and is prone to failure.

Any help is gladly appreciated.

Answer
If I understand you correctly, you have a flash code 47, which indicates high resistance in the passenger side belt pretensioner circuit. TSB 04-2-4 applies to this problem.

I never recommend air bag repair as a DIY project. There are too many ways to cause problems or possibly set off an air bag accidently if the proper procdures are not followed. I cannot copy the TSB here, you can find it on the NHTSA site, or maybe motorcraft.com.
