How to fix your Toyota Microphone

[@danieleliat9615]

I had the same problem with my 2014 Toyota Avalon Hybrid Limited. I just came back from the dealership who said they would charge me $250 for diagnosis and then the cost of repair. I said I would call back to schedule an appointment. Meanwhile I googled the problem and watched this video. Guess what, after 35 minutes of disconnecting the battery, everything is working like a charm again. Thank you so much for this simple and very effective tip.

[@vinn283]

Two-year-old vid, but I've been having this issue since I bought the car brand new in 2019. I got tired of not being able to be heard in phone calls and had to turn on the speaker mode on my phone itself. This video fixed it for me and it makes having phone calls so much easier now. Again, old vid but I can't thank you enough for the fix!

[@RobSAtlanta]

OMG! Thank you so much for posting this. My symptoms, in addition to the microphone not working for phone calls, was that my right passenger door's big oval speaker in my Sienna was not working! I am out of warranty, and hesitant to go to a Toyota dealership and have my dash board pulled out, and hesitant to go to a stereo shop. Buy your fix fixed both!!! After 30 min., reconnected the battery, and the green light comes on as you suggest, and it wants to download a software update. It downloaded, installed, and all is well with the right speaker and the microphone.

[@vondellelliott8313]

Thank you!! Toyota dealership knew NOTHING about how to fix the problem with my phone microphone on my 2019 Highlander. I disconnected the negative battery post for 3 hrs and it now WORKS! Very easy fix ... wish Toyota dealership knew how to fix their problems. I had a previous problem with the navigation not talking to me and my messages not being read aloud ... that fix I also Googled and it was to just push the start button 2x before putting your foot on the brake and then starting engine. Works every time. Kind of a nuisance to remember, though.

[@theresaperry6722]

This is 100% spot on. No one could hear me when they called me in my car but I could hear them. I could no longer remotely start my car with the app on my phone. I couldn't start my car with my key fob! Unplugged the battery for about 3 hours, plugged it back in and everything works!!! Thank you so much for saving me time and money!!!!

[@melanyaltuna7500]

2 years I had this thing broken!. Took my car to the dealership they wanted to charge me 280$ for this, I was upset and told them I will fix it myself. Saw this video, disconnected the battery over night and it totally worked!.. Thank you so much for sharing.

[@FredZ49]

We spent hours troubleshooting the issue with our 2019 Toyota Sienna. We were at our wits end. Then I found your video and we disconnected the battery overnight. This morning we reconnected the negative cable and all works perfectly. Thank you ever so much for your help and spending the time to share it with us. We are now aware that the Data Communication Module (DCM) may need to be hard rebooted whenever we have problems with our car and the connection to our cell phones.

[@10milesgilly39]

Did this fix your dcm? I'm having trouble with my sos button being active

[@TiMmMAAaaa]

There is now a DMC update for this issue

[@FranSmythe]

Thanks! I wanted you to know my green light doesn’t stay on but I see it when I turn on my car again and after doing what you said my sos (light in red) I can see again and now I can hear the person on the other end of my call again. Yea!!!

[@pv3782]

Fixed in less than 20 minutes, detached my negative connection like you said. Thank you. Definitely beats going to the dealer

[@RamseyKantunCaamal]

I literally just did this on my 2019 Corolla Hatchback XSE. I did everything except for the pulling the fuse option. Then came across this gem and after only 30 minutes, problem solved. Thank you so much for your video. Give this man a medal!! 🏅👍🏽

[@kathleensprinkle4308]

This trick also works on Lexus vehicles with the same problem. I just did it with my NX 300 and it corrected the issue. Thanks!!!

[@jimzimmerman5288]

What about losing the computer memory? Did that not happen? Thanks

[@theswabbie30]

I left you a note that I was having a similar problem with my wife 2016 Camry XLE. I disconnected the battery for about an hour and reconnected it and it fixed the problem. Thank you so much for your help

[@theswabbie30]

So, two weeks later I had the problem again. I did the same fix of disconnecting the battery for a couple of hours, reconnecting and the problem was solved. I hope this is not a way of live for my wife's car.

[@tionnarobinson9872]

It worked!!. I have a 2016 Toyota corolla. My husband removed the negative from the battery for 30 - 45 minutes. This video was a blessing to me... Thanx

[@brianruperti]

21 Tacoma people couldn’t hear me speak when I call on Bluetooth. Deleted phone from truck. Deleted truck from phone. Turned truck off for a minute. Started truck, reconnected phone. Set call shortcuts on Home Screen again. Good to go! Now they can hear me again. Thanks God bless!

[@Oliver.rondon]

Thank you very much for this tip, it worked perfectly, I just disconnected the negative battery port overnight and the microphone works perfectly. You saved me tedious trip to the dealership.

[@mjhenches]

2019 Toyota Sequoia, Microphone did not work. I tried this trick with a two hour disconnection. I learned from trouble shooting PC's and Mac's always try again. I took the second tip and tried it again over night , about 16 hours. I also disconnected the positive and negative the second time. This time it worked. Always try fixes more than once, you will be surprised what happens sometimes. Thank you Car Nut for this brilliant fix.

[@JWLC2012]

Exceptional, thanks. Worked on my 2018 Nissan Rogue SL. I unplugged the negative battery terminal for 2 hours. When I reconnected the SOS light came on, microphone started to work, etc. Going to cancel my service appointment!

[@fzprime]

2019 Toyota Sienna. I had the exact problem described. Another symptom was the front passenger speaker was silent, which makes songs recorded in stereo very obvious! I was convinced there was some issue with a fuse, except every fuse tested was fine. Disconnect of the battery for 35 minutes and all issues were resolved. Thank you!

[@pacrimco]

Took this exact problem to my local Toyota dealer, along with your video suggesting a battery hard disconnect fix. They said they did the disconnect but the head unit needed replacement for $1,000+ parts, plus the installation labor costs. Later, after negotiations with the service manager, they said Toyota would provide a free "favored customer" head unit and I would pay $200 installation costs. I subsequently picked up my 2019 RAV 4 hybrid, awaiting the arrival of the replacement head unit. When I drove out of the dealership, I immediately checked all the affected systems and there were absolutely NO problems. Thanks to your video and some research of Toyota service advisories, i won't be ripped off by this dealership because of their fraud or incompetency. Sadly, I can no longer trust this agency for repairs or service needs.

[@davidsainthilaire]

I have a 2019 Prius limited and it work, remove the negative for 30 minutes and boom!!! Everything is good! You are the man!

[@AndyHa1010]

My Rolla 2020 Microphone and right speakers stopped working. I didn't try this method but rather remove the 7.5 DCM Fuse under the hood. Start the car, shut off, put fuse back. Now everything is working fine.

[@RukatheBlackfish]

It wasn’t an interior fuse?

[@RukatheBlackfish]

I googled it! Thanks for this tip. I’m going to try it first since it is my right speaker that doesn’t work as well. I really thought it would be an interior fuse

[@BrandonsBackinBlack]

Woah! Gonna try this as my right speaker stopped working as well.

[@juniorq5213]

This totally work too thank you !!

[@armedpreacher]

This problem was driving me NUTS!! I thought it was an issue with my Apple Car Play. Thanks for the info!

[@jennyfitzsimmons7962]

Thank you so much! 🙌🏻 Once you mentioned the “little green light” I remembered it used to be on. I first tried disconnecting my phone from my car on my lunch break at work. Didn’t work. I showed my boyfriend this video (he’s a car guy) and he said it made sense to disconnect the battery. He did that for just over 30 min and it worked.

[@ArizonaMGD]

We have a 2020 Camary and have had it to the dealership 3 times due to when someone is talking to us while we're using the Bluetooth they say it's very annoying due to all the noise. I took the negative terminal off and left it off all night and wallah, it worked great. Can't wait to call the dealership Monday and let them know how to fix it. Thanks for your help!

[@trav-Elr]

Regarding the software updates that can only be done at the dealership... Which ones? It would be great if you would do a short video about software and updates specifically. Which ones can be done by the owner and which ones have to be done at the dealership. Thanks

[@Paul-qn4vd]

Thank you. Thank you. This just worked on my 2012 Toyota Avalon (90,000 mi.). Detached negative terminal for 30 minutes. Reattached. Could now use voice commands to pair my new phone. Before that, unit would simply say "Pardon" in response to my commands since microphone didn't work. Called my wife from garage and hands free worked perfectly. Don't know if I should expect it to freeze up again but at least know the fix. Great video.

[@persistence4752]

Thank you again! I disconnected the neg battery cable for 2.5 hours and it didn’t fixed the problem. Then I disconnected the neg battery cable again and left it off over night. I reconnected it the next morning. Problem solved. Your awesome!

[@randygouge2653]

This totally works! Had an estimate from the dealer for $385 as the starting point for replacing the microphone. You are a lifesaver!

[@cherwalker9080]

Just saw your video wish I would have known that sooner I have a 2019 Prius I spent 4hrs at the dealership for a new microphone didn't have to pay anything because it's still under warranty but that's 4hrs I'll never get back will definitely save this video again thank you wish I would have found you sooner.

[@williamsjasonp4]

My son has a 2019 Avalon. Microphone and one speaker not working. I sent him this video and BAM! Fixed.

[@davegeng2068]

Thank you! Disconnecting the battery cable on my 2019 Avalon Touring solved the problem and saved me the $169 estimated cost for diagnosis! Sounds like a known problem that Toyota should notify their customers about directly. How many customers don't know how to search for trouble shooting tips and have to pay out an extra $$$ unnecessarily? :( Too many! God Bless You!

[@glennmoore4865]

Thanks. I was looking for a fix on you tube and tried resetting entune , removing and reinstalling bluetooth and nothing else worked but this. I am very grateful for this video. Thanks. It definitely got a 👍

[@shoescorner2850]

It worked for me , The radio was rebooting , microphone was not working , follow this instructions and voila ! , thank you , saved me over 1000 , ene the 140 diagnostic charge , thanks thanks !

[@Collettels]

This worked (the unplug the battery thing)!!! Saved us $$$$$ from having to go to the dealer.

[@AgustinReyesLopez-m8u]

It worked! I disconnected the battery on my Sienna over night and BAMM! Thank you! You save me some headache and $$

[@bonbon0710]

my right side front speaker and microphone didn't work and unplugged the battery overnight made EVERYTHING WORKS AGAIN!! Thanks so so so much!!😁😁😁

[@lorenabort9717]

THANK YOU!!! Everything you said was exactly correct! We fixed my Sienna in less than two hours!!!

[@lisaloufitzpatrick]

I just filed a complaint with the NHTSA about the issue-what if we had needed the SOS button??

[@christinerogers3397]

Fixed...saved me several hundreds of dollars (which was my estimated repair cost from dealership) and time. Thank You!!!!

[@mariemireles3825]

I'm having issues with my 2013 Highlander, radio/Bluetooth sounds fine, until I'm on a call, then it's VERY staticy. Any suggestions?

[@valeriepayton2534]

OMG! This TOTALLY worked! Thank you so much!! I just recently purchased a 2021 camry xse and it started doing this a couple of days after I purchased it. No help from the dealer. Thanks again!!

[@dougschmucker8212]

Worked like a charm! Over nighted it. Later, Asked my service rep today .. at least there’s one guy who knows about this fix. Thanks!

[@johnday7988]

Very clear video with simple instructions to fix something you'd have to pay the dealer over $100 just to diagnose. Unfortunately, my Prius C is a 2015, older than the model year range covered by this video. .

[@claudeparadis997]

Merci!

[@crimestoppers1877]

This is good information. I also learned how to temporarily disable All microphones inside a Toyota whether they were installed by Toyota or others who may have a sneaky intent. I use an inexpensive 25 KHz Ultrasonic Piezo transducer powered by a 5 volt power supply and I place this in a convenient location inside the vehicle. When I want to use the Toyota installed Bluetooth microphone when using my cellphone, I just turn off the transducer and all microphones inside the car whether they are in a smartphone or part of the Bluetooth system return to normal function. When I need privacy I turn on my ultrasonic Microphone blaster and now have privacy restored. The audio frequency is so high that you can not hear (humans can only hear to a maximum of 20KHz) it but it causes a temporary scrambling of the microphone sensor membrane to jam all voice sounds. Any dog, cat or parrot you might have as a companion in the vehicle might not appreciate the 25KHz ultrasonic sounds since they might hear it

[@thewordofgodPR]

Great video, used your tip(2018 Toyota Sienna limited premium) and problem was solved. I left my cable off overnight, and the next morning..my microphone function was back. Thanks

[@allymonami]

Your tip saved me! I disconnected my battery for 30 minutes. I put it back. My car is fine now.

[@joshmcnair8168]

Thank you for your video. Just tried this and it fixed my issue within the hour on my 2019 Toyota Corolla hatchback.

[@angielollar645]

I'm totally trying this when I get home (and get hubby to do it lol) - My 2021 Rav4 did this and now I've got a 2020 4 Runner that is doing the exact same thing! I had an iphone with the Rav and I with the 4 Runner, I've had both iphone and now Android. The issue doesn't seem to be phone related as I can switch to speaker phone and all is well. I'll repost an update after we try this fix. Thank you for sharing!

[@KE5ZZO]

My problem : I drive past a certain house and microphone turns on like I pressed the talk button. Is this my car? Or is that house the culprit?

[@BirdlySV]

30 minutes later and it works again. Thank you for the video.

[@ntbrown674]

Your explanation was great. It worked, thank you. I have the cell phone audio back.

[@leeannlopez8295]

This worked! Thank you so much. Now I can cancel my appointment to the dealership. It also helped my system be reset for automatic updates.

[@elzey6956]

I tried the removing the 7.5 fuse for the DCM and it worked like a charm. Thank you, thank you!!!!!

[@hapton8]

on 2019 rav4 hy: Interior fuse box DCIM fuse is 7th fuse down from the forward left fuse. worked like a champ. pulled fuse for about 3 minutes, put it in, heard a chirp and all is well. A hell of alot easier then disconnecting battery, at least on my hybrid.

[@aircraftmaintenancerecords7371]

Totally disagree. Easier to remove the batt neg connector than that fuse, unless you have an special fuse removal tool.

[@alfaepsilon1]

On Yaris dated 2020 it worked !! The problem was the DCM freezing . Very happy about it

[@ernstgrafenberg5347]

Thanks a lot. As suggested by others I removed the DCM fuse from the interior fuse box of a RAV4 MY19 and It worked.

[@geraldcadyii5772]

I have to ask you, why did you do that? Your machine is under warranty, make Toyota fix it now or you will be stuck with this problem forever as long as you own this vehicle.

[@andysorbet4684]

Thank you for posting!! I just did this to my Corolla hatchback and it worked (disconnected neg for 2 hours). Fixed the passenger speakers as well (they stopped working at the same time as the mic). 👍👍👍

[@nicholasgianoplus3904]

Thank you so much for this video! I followed your advice and disconnected the negative terminal overnight. My only precaution / recommendation would be to make sure your car is in a position to be jump started. I was unable to even shift my car out of park after reconnecting the terminal. Probably some fault on my end that the battery went completely dead but I figured I would share. Thanks again! I finally have my sanity and can make phone calls.

[@thomasstrickland0]

I’m sitting at the Toyota dealership right this minute trying to get this fixed right now.

[@williemaykit7940]

Does this work for the background noise from the 4Runner? My wife hears me clearly, but her calls from the Toyota have a background noise like static, or driving with the window open.

However now I do not have the option of (Dictation Reply) to an incoming text and I dread going back to the dealer. Do you have any suggestions on how I can get that option back?

So my 2020 Toyota Camry is doing the same thing people can’t hear me on my Bluetooth but I can hear them.

[@ardv28]

Wow! Thanks for this vid but before doing this, try the fuse fix first. Like others commented, removing the DCM fuse did the trick for me. Just pull the 7.5 fuse out with the puller included on the relay cover for a minute, not 30, not overnight, maybe even just pull and put it back and it should do the trick.

[@cobraclips]

I'm assuming the car has to be off when you pull this fuse and put it back?

[@d1bergman]

Good to know but, disconnecting the battery causes other issues no? What happens when you disconnect the battery? Next this doesn't address the problem of why it locks up plus Toyota doesn't get to know who has the problem. Will a new DCM fix the problem from happening again? I have a 2018 Camry LE and I don't know where the DCM is located nor do I remember ever seeing it. Where is it located? Thanks David

[@TheCarCareNut]

Hi! There’s a software update not to resolve this issue if it’s reoccurring. Also disconnecting the battery shouldn’t cause any issues

[@stephanelambert5751]

Unfortunately this didn’t work for me on our 2018 Lexus NX300. I unplugged the battery for 4-5 hours and pulled the DCM fuse out but my Bluetooth mic still doesn’t work ☹️ So this means the actual mic or DCM are just shot ( and not just frozen)?
