Passive entry /no key fob detected

[Dcornz]

So a few days ago my passive entry quit working /no key fob detected
Figured it was the battery in the fob, same results with new battery

Fob works as it should for unlock lock ect

To start the truck I have to push the button with the fob
Tried unhooking truck battery multiple times

I'm getting a code in alpha I will attach a picture

Does anyone know where antenna #3 is supposed to be?

Posting info about your truck can be helpful (model year, etc). But do you know if you have had or have the rear window leak? The security module is on the back wall and can get damaged if there is a leak.

2020 rebel 5.7 non e torque sorry

The window is a little leaky, I had the RF hub out last night with no signs of water intrusion or corrosion, no signs of water in that general area

I had mine replaced with no water problems at all. JUST A BAD RF HUB.

Was it still reading your tire pressures? What kinda cost is associated with that

Everything worked except the PTS and passive entry. Can't remember the cost, but several hundred.

AFAIK, on the rear wall, should plug into the RF hub.

There are LF antennas in the center console, front doors, back cab wall, and under the rear bumper. The PTS may have one integrated into it also. I pretty much chased all of them down and checked them before taking it to the dealer.

I found the one in the back door drivers side I unplugged it and it threw a code for antenna #1, I unplugged the one behind the seats and it threw the #3 code and a open circuit so I got it narrowed down to it, I just ordered a new one, I'll give it a go hoping the issue isn't the RF hub but I will know soon enough

 

[Dcornz]

Looking more like an rf hub, truck wouldn't respond to anything this morning nothing on the key fob and no response from the push button

Final update on my issue, sent to the dealer let them diagnose the issue they found a broken wire and one half chafed through on by the drivers seat belt

Text from the tech
