Whining noise from radio on aux

[07SalsaSportEd]

Anyone else have this problem? I have a 2007 and when I use my satellite radio (connected through aux port) I get a high pitched whine, especially when I accelerate. Anyone know if this would be covered under a certified warranty?

Stop listening to emo bands.



In all seriousness though, you have a ground loop. I would try the warranty first, if its the factory auxiliary in it should be covered.

Trying to listen to Sirius....Howard Stern to be specific

I assume you have a portable sat radio that is connected to power as well. Try plugging in a device to the jack that is battery powered while playing audio and see if the issue still occurs. You need to see if it is the device or the truck before you progress futher.

 

[07SalsaSportEd]

definitely not the device, it is hard wired to the battery. Have also tried using my ipod, still makes the noise.

I have the same problem but only when im using the AUX connected to my ipod AND connected to the cig lighter to charge my ipod at the same time. ground loop? as in bad ground?

 

[sheik]

When two or more devices are connected to a common ground through different paths, a ground loop occurs. Currents flow through these multiple paths and develop voltages which can cause damage, noise or 50Hz/60Hz hum in audio or video equipment. To prevent ground loops, all signal grounds need to go to one common point and when two grounding points cannot be avoided, one side must isolate the signal and grounds from the other.

They can be a real pain to track down.

There is a TSB for this. Something to do with grounding the wire. I'm in Canada and they tried to give me a hard time saying it only applied to American bought vehicles, but they eventually fixed it (or very nearly-there is still a SLIGHT wine when I have the volume turned up real loud). If the device you used is not powered by the truck (like an ipod just using the battery) there will be no wine. Regardless, bring it to your nearest dealer and they'll fix it up gratis!

Here's a link to an old thread on this. I think there's a link to the TSB on there somewhere

It is TSB # T-SB-0067-08.

I am trying to get the stealer to fix that on mine right now.
Took it in once after telling them the problem and give them the TSB they ordered the parts. Next week I took it back, but after an hour they finally said they did not get everything they needed. I think the ordered the installation kit, but not the part. Now another week later it is slated to be put in this Friday (2 1/2 weeks later). I'll report back then.

The point is - If you take it in for this under the 36K warranty, you are probably best off to give them the TSB # and tell them to get the parts first, noting to them that it has both the installation kit and the parts as well.

You can also fix it with a radioshack part and and a few adapters.
Ground Loop Isolator - RadioShack.com

I did that and it worked, but want the factory / warranty install now.

Actually, most dealers will frown upon customers coming in with the TSB in hand. Remember... the dealer has no obligation to fix a vehicle just because there is a TSB available. Only if the vehicle exhibits the conditions described in the TSB.

Best case scenario is to describe to the dealer what the vehicle is doing (closely worded to the TSB... try to not to copy it word for word.) If the dealer gives you some pushback on the repair, the best thing to tell them is that you contacted Toyota's customer experience 1-800 number where they made you aware of TSB # (etc, etc) and you are aware it is available for your vehicle. Remember... not all TSB apply to all vehicles of that make and model. In some cases it is only a certain VIN range. However, if your vehicle is experiencing the concern, and there is a TSB for it, chances are that you are part of that VIN range anyway.

I would also suggest giving the dealer very concise information about when, where, how the problem occurs and in some cases go so far as to request the technician ride with you so you can duplicate it with them. This eliminates multiple visits, unneeded phone calls, etc.

I speak from experience as a Service Manager for a Toyota dealer. I can't speak for what everyone else's dealer may do, just how it is handled by my dealer.

I had that problem and the dealership fixed it under my extended warranty.....so far the only thing my extended has covered to date! (That's a good thing ).

It happened when I listened to sirius (plug and play) and when I plugged my mp3 in to charge while listening....

 

[Arcking]

I took the TSB into my dealer and after demonstrating the problem they took care of it ASAP. Sounds a lot better now.

I actually initially scheduled the service for 3 things saying I had problems with noise on the aux input on the stereo, wanted my propeller shaft re-torqued, and a mechanical inspection done for 30k (but no service other than that). In discussions after I arrived, they had problems locating a reference to any audio TSB on my '08.
I told them I found a TSB about it when looking on the internet about the problem I had. I had a copy in the truck I gave them then.
I would agree with what you said about the way to approach things, but it may still be handy to keep a copy of the TSB with you since this appears to be only occasionally reported.

Note: the TSB says you need to take care of it in the first 3yr/36K.

This repair is covered under the Toyota Comprehensive Warranty. This warranty is in effect for 36 months or 36,000 miles, whichever occurs first, from the vehicle’s in-service date.
Warranty application is limited to correction of a problem based upon a customer’s specific complaint.

I agree with this completely. Nothing wrong with having something to reference if they have a hard time finding it. Again, I can't speak for every dealer, but searching for a TSB should be as simple as typing in "whine" or "aux" in our TIS database and it will pop right up.

I would keep a copy in the glovebox or out of view. You will have much better luck with this instead of walking in and slapping the paperwork down on the desk and just saying "fix this". Also, I would recommend avoiding mentioning things like "well, this forum I am on said..." or "I did a google search and found..." as the dealer will argue that you can literally find ANYTHING on the internet but it doesnt make it correct. I cant tell you how many Prius customers come in and say "I read on the internet that this guy is getting 70MPG, why is mine only 50MPG?" :redbrick: :redbrick: :redbrick:

Also keeping the TSB out of view of the technician prevents them from reporting back to the service advisor that it looks like you are "warranty fishing". Trust me, it happens. Although the technicians are paid to perform warranty work just like customer pay work, they are less likely to want to open a can of worms on a vehicle where they know the owner is going to complain about anything and everything in an attempt to get as many parts replaced for free as possible before the warranty runs out.

Note: the TSB says you need to take care of it in the first 3yr/36K.

This is true for 97% of all TSBs with the exception being powertrain warranty items (5yrs/60K miles) and federal emissions items (8yrs/80K miles).


**NOTE - I hope to bring some dealership perspective to the forums. I'm not asking anyone who has had a bad experience with their dealership to change their mind, but please also understand that dealers can have major variations between service practices from one to another. While there is a stigma that the dealer is always out to get someone, or is way too expensive, etc... that doesnt mean thats every dealer everywhere.

I'm not asking to change opinions at all, but I also dont want to offer this type of perspective in an attempt to help people get their warranty work processed a little easier and be written off due to bad experiences at other dealerships. I truly am offering this advice/information in the hopes that it helps you guys.

Yeah, that's what I thought. Seems like after I mentioned the problem, they would have found the TSB right off.

Yeah I didn't want to come off like that, but I did leave it in the vehicle on the seat once they said they could not find it.
At the local dealer you only get to talk with the adviser and he interfaces with the tech. So he already knew before that. He was also the one doing the search on the TSB.

Thanks for the perspective ! There is more that one viewpoint in most situations.

I have been having this issue for a while now. Just changed the oil this past weekend and switched to 10w40 and the noise is gone!
