No Audio 2017 Tacoma

Hey yall, I’m new here. So I lost all audio in my truck. Head unit still works like it always has, just no audio is coming out at all.

Got my buddy to run a scan on it and it’s coming back with two error codes.
U0163 Lost Communication with navigation control module
B150A Lost communication with HMI - LAN

I’ve checked the fuses for the radio and ACC. Both are good. I’ve reset the head unit and issue is still there.
Any suggestions to getting the issue fixed?

 

I hate to say it but you’re better off getting a better head unit. You’ll definitely notice a huge improvement over the factory unit.

 

I just didn’t know if it was a wiring issue or a head unit issue. I’ve been thinking of getting a better head unit anyways, but I wasn’t sure if I should see if it was a wiring issue first.

 

It could be the wiring in the dash speakers is causing the issue. But you said no sound at all leading to head unit failure. Watch a couple of videos on how to pull it out and look at the connections on the back . My bad not the speaker but the radio connection.

 

I’ll pull it out and check some of the wires. Thanks for the help.

 

You never mentioned if it’s the jbl or regular entune?

 

Rodents??

 

I would try unhooking the Negative battery cable for a minute to see if that clears things up. If you still have no sound, this video may be helpful in pulling the head unit.

maybe the amp fried?

 

Here’s how to do a hard reset along with a soft reset .

 

not jbl

 

I’ve tried both already :/

 

I can not find the amp to save my life.

 

not to my knowledge. No signs of anything.

 

I would assume that it's built into the head unit putting out signal to the speakers.
But i honestly don't know much about these head units so you would have to research it.

 

Check out this thread. Post #2 has a good diagnostic tip. Post #7 talks about a common problem of the heat sink on the internal amp coming loose causing the amp to overheat and fail.
