Entune stereo turns itself on and off by itself

I understand your frustrations and surprise at the same time because it happened with the new. Myself for sure would be able to help as I know others here too. We need to duplicate it or test when it's not on. Does it shut off then power right back on or do you have to do something to get it to come back on? How long does it go off and stay off? How often does this happen ( let's say in 10 or 20 or 100 tries )? Does it happen when you hit a bump? Do you lose memory presets or clock on the stereo? Many things it can be but CAN be fixed.

 

Hi there and thank you for responding. Any and all advice is very much appreciated! Now let me answer your questions, it does shut off and power back on itself mostly within at least roughly 15 seconds or so sometimes longer without me having to do anything to it. Some days it shuts off more times than others and then again sometimes it will work fine for awhile (days or a week or so) then start doing it again. Yesterday after the new install no problem, today it happened twice. I'll be driving on flat roads no bumps or anything of the sort and all the memory presets and clock stays correct. Hope this helps at least a little.

 

do you have the jbl system in your truck? is the new stereo doing the EXACT same things as the old? give me a model number to the stereo you have in there now. we do know this
if the symptoms are the EXACT same, its not the new radio. that also means its probably not the old stereo either. there are harnesses that plug into the factory stereo. when adding an amp/sub most likely the people that installed it added a lineout converter to that wiring harness. there may also be an amp turn on wire back there too. IF those 2 things are hooked up the FACTORY harness, they need to be removed and the amp turn on wire needs to go to the amp turn on wire on the new stereo. if you have rcas plugged into a loc behind the radio for the amp again that needs to be removed and the rcas needs to be plugged into the new stereo if it has a sub out. now, when you bought the stereo you have got or bought a Toyota wiring harness that plugs into the factory harness and then gets wired to the new stereo harness. the best way to know whats going on voltage wise is to meter it when its not on. that tells you what wire is dropping. if you are keeping your memory that tells me that your constant wire is not the issue. of course that's all depending on the fact that when the radio loses power that its actually off long enough to affect the memory ( yellow) wire. the red wire (Which is the turn on and off wire to the stereo ) sounds like that's the one we need to be looking at. I have seen where the pins for the power ( black, red and yellow ) have been misaligned or not seated properly. it can also be the circuit that the radio works on. maybe you have other accessories that are on the same circuit who knows. if you cant get the stereo to stay off to meter it, have a reputable installer NOT cut the whole harness but bypass the factory harness for power. that also includes the harness that you should have bought. new radio harness black, red and yellow wire cut loose ( but leave slack to ever reconnect it ) and have them put the black wire to GOOD metal behind the stereo ( there is plenty ) run the red and yellow wire to the ignition harness ( there are other circuits that you can use but these are guaranteed because they run the truck and have plenty of amperage to support a radio. doesn't draw too much current ) also because the ign harness is easy to get to. have them hook the yellow wire to white with a blue stripe or a white with a red stripe. the red wire needs to be hooked to a white with green wire. you now by doing this bypasses the factory wiring and correctly wires an amp and sub behind the radio. good luck do this and then get back

 

My truck doesn't not have the jbl system and yes it is doing the exact same thing as the stock HU. I got the pioneer avh x4800bs. And yes there is a line out converter or atleast there was one back there before! All I know is when I watched the first guy do it he was yanking pins out of the stock harness with a little screw driver that was getting him very angry because he couldn't get it out and so he was not being careful about it and now I don't know much about stereo installations but I'm thinking that has something to do with all what's going on! I just hope and pray this can all get settled and the stereo guy can figure this all out! He does seem confused though and don't understand why the clock goes out at the same time as the stereo as well and why my USB port don't work either. I tried to get a video of it this morning when it did it to show what it does and also notice the iPod go on at the same time as the stereo because the power down in that area goes out too. As for right now it's completely off and won't go back on!

P.S. well so much for the video it won't let me post it!

 

As far as I have researched there is a tab out yoy can have toyota do an update on the head unit. Heard mix things as it has totally solved some problems and made some problems worse

 

What is the gray wire for in the stock wire harness?

And ... Isn't the update for entune stereos only?

 

update has nothing to do with this situation because its happening with the new stereo. if your not getting power at all, yes I know that sucks but that IS a great thing for troubleshooting. that's what we want to happen. duplicate the problem isolate it and fix it. your stereo installer needs to meter the harness for power at the harness (black pioneer plug) going INTO THE RADIO not before. if your factory clock ( I assume that's what your talking about ) isn't working then you probably have a blown fuse. many vehicles have clocks cig sockets dome lights and radios on the same circuit. I know your trying to post a video but you need to have that radio out and them take pics and post them. maybe I can see something.

 

Well my truck was supposed to have gone in today to the installer but got cancelled so I'm crossing my fingers for Wednesday like he mentioned. I will try and get some pictures of the back of the stereo if I can be there when he is doing it. Thanks again, I will mention to him all that you suggested and hopefully we can get this problem solved.

 

Yet again today's appointment got cancelled! Rescheduled for Saturday, this is all so depressing and worrisome!! Riding around with no sound at all sucks!!! Could further damage as in shorting things out and such happen since it's still not dealt with? Also, does anyone have the wiring diagram for the harness that connects to the deck? I was told by the installer the previous guy cut the grey wire off the harness but I don't know what that's for.

 

What? Why?.... I will say the factory accessory wire is gray. That might be part of the problem. As for doing more damage.... no because the damage is already done. You have no power. Either take it somewhere else or wait but need pics of behind radio. Until then, it's just a waiting game and no sense worrying about it until then

 

Ok, so finally got my truck looked at again and the installer found out that the accessory line has a problem from the fuse box. When he tested that area it was dead at first and then started clicking off and on. I was told the stock harness looked ok even though wires were cut from it. He said he ran his own wire from the stereo tapping into the fuse box by passing the accessory line to make the stereo work but its over his head being that the problem is the fuse box and I need to take it into Toyota to get it looked at. Yay for me because that's gonna be expensive!! I tried to get pictures but wasn't there long enough while he worked but managed to get a couple that I don't know if will help or not but here you go.

 

What the hell?!?!?!?.... what a mess... so I can see you have an amp in there powering your speakers but the pics don't unfortunately do any justice. Is the radio out or put back into the dash? Also, do you know if ANY other accessories ( cig socket, dome light etc ) stop working when the radio power was lost? Did he say if the radio fuse was blown? If nothing was wrong other than the radio and he truest did bypass the factory wiring ( still can't tell by the pics ) then no need for the dealer. I see factory wiring go bad for some reason all the time. In an earlier post of mine I told you what wires needed to go to the ignition harness for the installer to do IF he had to run new wires. NOT. The fuse box but it is what it is

 

Yes it is a mess!! Pardon my French but it literally is a cluster fuck!! Sorry about the pictures that is all I could get. The radio is back in with that by pass wire and although I know you told me which wires to connect to do that the stereo installer did it his way cause I'm just a girl and what do I know. From what I could gather he only did 1 wire from the stereo to a wire in the fuse box to by pass the bad accessory thing! Anyway, the dome light still worked while the clock, USB and cig socket did not. Fuse on the deck itself was still good and wasn't blown. I have to call Toyota tomorrow and will probably end up having to give them my first born for payment for whatever this will cost!! I took a picture of the wire he put in to get it to play (red wire to white wire with blue strip) but I'm sure that still won't help. it's weird that if you jiggle that accessory fuse itself the power goes off and on. So as of right now my clock, USB and cig sockets are working for the time being! Thank you again for all your help and advice. Wish you were here in Hawaii because I'd definately take my truck to you!! Hopefully I won't end up having to sell it!

 

I can't seem to turn my head unit off when the key is on accessory. If I hold the power button down, it just reboots. If I push the power button, it toggles through audio modes. It won't turn off and stay off.
