Hello greetings to everyone. I had a quick question. I’m working on my 2014 Cadillac XTS premium with the 3.6 VVT direct injection engine and I’m having a hard time finding and locating the engine knock sensor. If anyone has a picture a diagram that can demonstrate the location. I will highly appreciate you thank you have a blessed day

So I was messing around with my new ob2 scanner & I was testing a few features & functions it comes with. I learned a while back how to relearn the ac actuators by certain features this scanner allows you to do, and well I fixed an actuator by just relearning its blend positions. So I tried seeing what would happen if I hit the relearn auto leveling headlights function, after a few seconds it said relearn test not complete. And now I have this yellow icon on the left side of the dash & two pop ups. This picture is taken while car is in ignition mode (acc) once the car is turned on. Theres no check engine light. Only light on dash its the left corner one yellow with headlamp sign. Any suggestions on fixing this? My lights are oem factory and are both functioning properly. Im guessing maybe it lost connection to the ecm? Thoughts?

Thanks in advance!
