I down loaded Jscan, got the suggested device from Amazon.

I down loaded Jscan, got the suggested device from Amazon.

It read my jeep, showed the vin etc. No codes.

You will only get emissions related codes for things that set the CEL, but you can't read the module specific codes unless you pay the extra licence fee ($20).

I didn't see that on the app

Under settings, look for Manage Licences

Looks like it's now $25

Yeah, it was 23.99 from the play store.

I have code B1A74-13 Radio frequency hub.

I'll investigate

Problem resolved.

Located Antenna 4 behind HVAC control panel. No screws holding panel. I used plastic trim pry tools. It requires a bit of force to separate.

Located antenna 4 directly behind panel. Traced wires, found broken wire. Likely a mouse chewed it.

Wire repaired with heat shrink solder splices.

Proximity and start working properly.

Thank you for everyone's help.

Jscan is worth the cost.

I was a mechanic 25 years ago. I changed to an entirely unrelated career, and have not worked professionally as a mechanic, long before this equipment existed. What I did learn back then, is to check all wires and connections prior to ordering parts.

Thanks again.

Great Job, who would have thought?? Strange things can happen. Take care!

I've actually seen that very same antenna be broken/have connector issues before. Sometimes unqualified individuals are just working back there (aftermarket radios for example) and rip shit around. Another extremely common one is the tailgate spare tire area mounted antenna in grand cherokees/durangos. Techs will pull out the spare tire housing and forget to unplug it, ripping the connector out. There's a lot of modules/wiring down there that we sometimes need access to so it comes out rather frequently.

This really does show the benefit of a proper scan tool. The code tells you exactly which antenna is causing the issue, and combined with the wiring diagram it's a five minute diagnostic to determine if it's a sensor, wire, or module issue once you've gained access to the components.
