Guys, I need your input, please. 2007 x5 4.8L


First, circled in red, does anyone know what is the black connector responsible for?


Fault cd8b (DME Local CAN communication). Fault is accompanied by hesitation at the throttle. Unable to clear code. Most recent attempt was to replace the body control module under the passenger side fuse box, but that was not the problem. So today I left the nt510 scanner on and decided to pull each connector from the fuse box then recheck the scanner. I came across a black connector that actually eliminated the cd8b fault, but instead, fault 2d00 came up, (DME: Throttle-valve actuator, spring test of closing spring). Please see pictures below of the particular black connector. After examining the throttle body, I see that there are green markings on it, which leads me to believe that it was replaced at one point from the previous owner. So is it safe to say that I need a new throttle body?
