Dave helped me systematically test and check various items found in the SRS manual he shared with me.

First we checked the contact reel (clock spring) per the instructions in the manual, and it tested just fine. We discovered a bridge clip in one of the orange connectors. We think it's to help protect the circuit. I added a picture of it to the photo stream.

Next we moved to checking all the connections from the airbag to the crash sensor. Those were pulled apart, cleaned, treated with anti-oxidation paste, and reconnected. This included all the orange connections as well as the yellow connector behind the carpet near center console. I did not detach the connector from the crash sensor. The connections all looked GREAT before the cleaning, so I was skeptical this would work.

After resetting the SRS light, the system has remained error free for over 250 miles, which is about 200 miles further than it has in the past. So I'm calling this resolved for now. There may have been something in one more more of the connectors causing more resistance than what the sensor was looking for.

Anyway, thank again to this forum and helping keep the 240 safe and running.

Onto fixing the driver's heated mirror before it gets too cold....
