SiriusXM disappeared

Maybe the new head

The XM antenna wire is the plug with the single wire in the center. It looks similar to the shark fin connector you posted earlier....

My guess is one of the 2 in pink circles

 

The looks of it. The sirius antenna is the white antenna on the lower right of the picture. It's usually the "D" looking plug. So by what you said the new module is not turning on the sirius module. The power looks like it'll be in that black plug somewhere. Maybe a wiring diag exists somewhere or something someone here knows. Cuz my 2018 is different and sirius is built in and the nav is separate. Later models is the other way around.

 

Thanks for the help everyone, looks like I'll have to see if I can find a wiring diagram.

 

Ok… somebody is going to short out something very expensive if you are playing around and probing circuits and “guessing” without a diagram and with the power connected.

The modules underneath the 2014-19 Entune systems are the XM receivers. On the 2020-24MY head units that second module is the navigation ECU. Both are not cheap to replace if you short them.

The XM connector is the single shielded gray cable with the black plastic connector. White is the GPS antenna. Everything else is power, speaker, video, etc. If it’s a larger grey wire it is shielded. Any connector with color (I.e not white) is shielded signal or data. The blue connector you were probing is high speed USB data from the telematics module to the nav ecu.

Disconnect the black connector and reseat it to ensure it is fully plugged in.

if you made an electrical modification and something changed, undo what was done and see if it fixes the problem.

 

Thanks for the advice. I put in a new main body ECU, and Sirius disappeared. When I put the old ECU back in, Sirius reappeared. I'm trying to get SiriusXM to work with the new main body ECU. This is in a 2024 SR5 Premium.

 

Bump. Still haven't figured this out. Hoping to get a fresh pair of eyes on it.

 

The main body ECU for the 2020-24MY is slightly different from the 2010-19MY, so take what I say with a grain of salt because I have yet to do full deep dive on it. From what I have gleaned, the 2020-24MY main body ECU tells certain systems like the radar cruise and lane departure camera what type of vehicle they are connected to, end destination market, etc. It is also a gateway ECU for other components. It is possible that something is not being recognized after swapping your ECU out even though physically nothing has changed. I would try and get a copy of Tech stream and see if you can go in and initialize it under a utility setting, or perform an ECU-ID sync. This can't be done in the 2020MY+ without a software interface unfortunately.

If memory serves you have already swapped the original one back in and everything went back to normal, correct? If so I would say it is not "seeing" a specific input. Re-initialization via tech stream may solve it.

 

Thank you for the help. Yes, everything did go back to normal after I put the old ECU back in. I have Techstream but I'm not that familiar with it and wasn't sure how to initialize the new ECU. I'll take another look.

 

Could always just use app on phone and use CarPlay or stream via bt or usb. Just a thought until figure it out.

 

This is what I've been doing now and then.

 

Mine mysteriously disappears occasionally and comes back. Trees and leaves will block the signal.

 

Just used Techstream to initialize the Main Body ECU, also did the same under Gateway ECU (same ECU?) and nothing changed. Not sure what you meant by an ECU-ID sync, I couldn't find anything like that in Techstream. I also did a Communication Bus Check and everything seems to be okay.
