Kicker tailgate speaker troubleshooting

Picked up my first truck the other day. 2019 Sierra AT4 which came equipped with the kicker boombox in the tailgate. It's bluetooth connection is very poor. It normally takes me several tries to turn my phone's bluetooth on and off as well as cycling the boombox pairing on and off to get the thing to sync.

 

Once it is synced, I can start playing a song on Amazon music, and without fail within 2-4 seconds the bluetooth disconnects. I've tried on my iphone as well as my wife's droid and both do the same thing. 

 

I can connect and play music through youtube, but as soon as I hit the volume + button 3 times the bluetooth disconnects. It's fine with one or two hits, but on the third hit it craps out every time. Total waste of money in my opinion and the dealership has no clue how to fix it or if it may need a software update or something.

 

Anyone else have the same issue?

My tailgate speaker worked fairly well before, but now I can't even get it to turn on. The connections and fuses seem ok unless I am missing one somewhere. Any ideas?

It sounds like an issue with the bluetooth receiver integrated within the Radio.  The following is the service procedure, but I would start with step 6.

 

Circuit/System Verification

 

Note: The MIT tool can be used to test either cellular phone or streaming audio functions. Refer to the tool instructions, and perform the appropriate test(s) related to the customers concern in the following steps.
  1. Verify no DTCs are present.  
    • If no DTCs are present

  2. Verify the A11 Radio calibrations are current.
    • If the radio calibrations are not current
      Reprogram the A11 Radio and re-evaluate the concern.
     
    • If no update calibrations are available
  3. Ignition ON, infotainment system ON.
  4. Verify the infotainment system successfully pairs with the MIT tool.
    • If the infotainment system does not successfully pair with the MIT tool.
     
    1. Perform the 3 vehicle Factory Resets located in Setting>System>Return to Factory Settings.
    2. Verify the infotainment system successfully pairs with the MIT tool.
      • If the infotainment system does not successfully pair with the MIT tool.
        Replace the A11 Radio.


       
     
    • If the infotainment system successfully pairs with the MIT tool.

  5. Verify the infotainment system successfully completes the desired feature test using the MIT tool.
    • If the feature test is successful but the audio is distorted.
      Refer to Speaker Malfunction
    • If the feature test is not successful
      Replace the A11 Radio.
     
    • If the feature test is successful

  6. Verify the customers device can be paired with the infotainment system.
    • If the device can not be paired with the infotainment system.
      Perform a reset on the device. Refer to device manufacture’s information.
     
    • Verify the customers device can be paired with the infotainment system.
      If the device still will not pair inform the customer the issue is with the device.
     
    • If the device successfully pairs with the infotainment system.

  7. Verify audio can be heard while streaming from the device.
    • If audio can not be heard while streaming.
      Ensure the volume on the device is turned up to an adequate level.
     
    • If audio can be heard while streaming.

  8. All OK.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the repair.

Needs to be replaced
Nothing to do with truck infotainment
That’s a kicker module not a GM one

I can't seem to find the fuse for trailer accessory power if one exists, but the in-line fuse at the t connection is good and everything is plugged in. Seems like the unit itself may be toast.

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Missing thrust bearing? And oil selection

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
