The first line on the DTC says Left Side Detection Modual, so figured it has 2 sensors, a left one and right one (not necessarily on vehicle's right)?

Dunno though, these blind spot and parking assist systems are new to me.

the blind spot modules are on the left & right inside the bumper cover behind the rear wheels, they look like a claymore, the 4 rear circles in the backbumper are the backup sensors.
I would clean the blind spot modules and concentrate on the left side one by whatever method you have available then pull the left side one's harness off and check it to see if the contacts are clean.
you can check the rear backup sensors by getting a helper and put in reverse with your foot on the brake and wave a hand in front of each of the 4 rear sensors they should all 4 beep individually, there is some other way to check them in the service manual but I would have to search for it.

K, so the two are completely seperate systems, gotchya.

I know the backup sensors work. Whenever I back out of my garage they're going crazy, with the edge of the door opening, then my trash cans on one side and a car parked in the driveway on the other side, flashing triangles all over my nav screen... Lol

Correct. Here’s a shot of one of the radar modules used for the blind zone alert. They sit in a bracket attached to the frame just behind each side of the bumper.

Where did you get your front/rear emblems?

LOL this ALSO needs a write-up!

A buddy of mine promised to show me how to do it. He talked me into buying all the stuff; polisher, pads, compound, etc. Then he went and had heart surgery and couldn't help me. He's fine, BTW.

Chemical guys has a YouTube channel....... everything you need is there brother. If I can do,so can you.

The right buffer/polishing machine is key tho. I have a DA from Griot's garage......it's impossible to burn your paint with it.

Remember, let the machine do the work and you're golden

Lews WOT runs we’re missing my KR pids so I had to redo it. As soon as I let off oil pressure dropped and dic said low oil pressure shut off engine... pulled over, checked for leaks, found none, restarted to have regular oil pressure again and slowly dropped to zero after 2-3 miles. Rinse repeat a couple times before I called roadside assistance.
