I'm showing a B0131 code in Techstream (pass side pretensioner squib). I've read @Cosmo Kramer 's excellent writeup here, but mine is intermittent. I can clear the code and it stays cleared for 2-3 starts, then comes beck. Sometimes it self-clears between starts. Anyone dealt with this, before I pull apart my B-pillar? Maybe a loose connection somewhere in the circuit?
