Open in Multiple Squib Circuits

I have open driver and passenger side squib circuits including the pretensioners. This wasn't right after an accident.

-No airbag deployment.
-SRS light is constant ON.
-I replaced my left pretensioner around 200K miles, but never changed my right pretensioner. Yet both P/T squibs showed open around the same time.
-I cleaned the contacts with isopropyl and CRC QD Electronics Cleaner.

Codes:
B0101
B0106
B0131
B0136

Insight appreciated.

Happy wrenching.

 

Have you checked the connectors at the SRS module?

 

Yes. And I cleaned all the contacts as well.

 

SRS circuits are kinda tricky to test, typically the easiest test is to put a resistor of the correct value in place of the component that is generating the code and seeing if the code clears.
