Hello I have a 2022 Chevy Silverado 1500 and I am having a grounding issue with the rear parking sensors. I've tested the ground coming from the parking assist control module to the rear harness where all 4 parking sensors connect too, the wiring shows no resistance and isn't open. According to the wiring diagram that I have the parking assist control module has a ground on G301B. I am having trouble on locating this ground location. Can you please help me out and tell me where the G301B ground is located?
