2016 Silverado High Country. 
Radio has been working great for years with no problems (SiriusXM). Turned the truck on today and nothing is working regarding SiriusXM however all other forms of radio or audio work. Im in a city and have never had XM issues before. Not sure what to do and haven't seen any recent forums with a good answer. Thanks in advance for any help or tips.

Welcome to the site.

 

Log into your XM account and send a refresh signal to the truck.

is it not working in a certain area, or is it dead everywhere ?

Dead everywhere, it was working just fine the day before, I have very few if any dead zones around where I live for an example. And it won’t let me reply for some reason to the other comment but I have exhausted all efforts through SXM help that’s why i came here. 
Thanks!

2nd guess:

 

With what you have described here this is either due to a fault with the antennae itself ( even if it looks o.k. the antennae itself can fail internally ) or the XM radio receiver. Both will cause this fault here as I have seen before.

What has to be done is to have the fault codes checked/read out of the radio and XM control unit using a compatible scan tool/computer that will plug into your vehicles data port that can communicate with all computers in your model. There will be at least one fault code set with this issue here that will help to diagnose and locate this fault. This has to be done with a fully compatible scan tool/computer that can read all the computers in your model.

I would say most common for this issue that I have seen is the XM receiver itself as these tend to fail and require replacement usually by a dealer as the old receiver has to be deactivated by the dealer and the new receiver activate in your model for it to work.

Appreciate all of that info and advice, I’ll get that checked asap. Thanks again!

Same issue for me! I’ve used Sirius xm before and all was fine then one day blocked signal. I’ve tried refreshing and spent multiple calls with Sirius and nothing has worked. They want to charge me $400 to replace my antenna.

The satellite antenna is separate but within the same shark fin on the roof. The seal at the bottom has been known to not drain water and flood the internals causing them to corrode and fail. Buy a new antenna with seal and replace.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Have considered installing a DC to DC charger in your camper to replace your isolator?

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
