2022 Chevy Silverado 1500

[ReneB]

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?

G301 historically has been on the left side of the front passenger seat. I would imagine a "B" suffix would suggest it's somewhere nearby and related to that ... but of course, automotive engineering of the past quarter century is rarely intuitive.

 

I don't have access to the service info necessary to find that. It costs too much! 

 

Might be worth buying an Alldata DIY subscription to obtain that info, and wiring diagrams. Can do one month, one year, or 3 years.

 

With a modern GM product, I'd HIGHLY recommend the 3 year plan. You're going to need it.

'22 LTD or New body?  Standard, ext or crew? Did find a G301b on a new body style ext/crew cab at the bottom of the left hand B pillar.
