So I discovered something.. After the first false crash detection a buddy found that the negative battery terminal clamp was loose on the post even though the bolt was tightened all the way. We stuck a paper clip between the clamp and the negative battery post and went back out on track just to have the same “false crash detection” happen after two laps. After restarting the car, I immediately came into pits and trailered the car home.
Yesterday I went out to check all of the crash sensors and connections to the RCM. Before I did that, I decided to pop the hood and make sure the terminal was still tight. Sure enough, the paper clip slipped out during the first lap and the clamp was loosely connected to the post again. It was so loose I could simply slide it off with ease.
To permanently fix the issue, I went to Advanced and picked up a proper battery terminal shim. I cut it in 1/2 so the clamp would slide over at maximum stretch then tightened the shit out of it. It’s not moving now.. I also sanded the paint off the factory grounding point on the body just for good measure.
I’m really hopeful this was the issue and $3 is all I needed to spend to fix it. Fingers crossed.. Now I just need to scrounge up $500 to go back to AMP and track test it before the next long weekend event coming up lol.
