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.
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!
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.
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.
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.
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!!!!
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.
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!! 🏅👍🏽
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
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.
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!
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.
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.
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
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.
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.
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!
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!
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 👍
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!
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!!!
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.
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!
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 !
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.
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
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.
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!!
I replaced several dcm’s for this problem and did a ton of the firmware updates when I was at the dealer... even though I am no longer there I love watching your videos to keep me in the loop.
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!
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). 👍👍👍
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.
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. .
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
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!
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
@@phillipmoore2586 I found the DCM 7.5 Amp fuse in the interior box of my RAV4 Hybrid. Gently popped up and left 2 hours disconnected et voit la, eCall and mic back to life! Thanks a lot Phillip and The Car Care Nut!
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
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.
Have a 2015 sienna limited, noticed the system that allows you to talk to people in the 3rd row through speakers was not working. SOS button was red… did your fix and everything works! Thanks!
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.
Thank you so much! My dealership just shrugged their shoulders when I asked them to figure it out. Said I could pay for them to explore what might be wrong but no promises
Thanks for the tip, excellent channel for a future Toyota owner like myself specially with an R4P with all those new bells and whistle included in them...
Did you have the prompt saying remote activation pending? I'm also trying to troubleshoot my car to see what will work instead of wasting time at the dealership
Thank You, Thank You, Thank You! 3 year old 2019 Rav4, started trying to call no one and no one could hear me!. I was hunting for a reset of the head unit and of course just out of warrenty. Old Socket set and 40 minutes later back to normal
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.
Thank u thus worked on my 2018 Toyota Sienna , and u also explained why it will would awesome video , I just kept it off for 5 mins and put it back ECU just need a reboot I assume,
Tk u I own a 2020 Toyota n am 75 been to service many times, same ol story they do not know or want me to.up trade. I did want u said n Voila it works.
I was praying and asking the Lord to fix this problem😭I am extremely busy with kids, hubby and parents and it was driving me crazy not being able to talk hands free in my van. I found this video the evening I prayed and it was straight from Him❤️❤️thank you so much!! And may the Lord bless you and keep you as well❤️thank you so so much. My hubby was able to fix the issue the way you said❤️❤️❤️❤️
An alternative especially for Hybrid vehicles is pull the DCM fuse located under steering wheel. Leave out for 10 minutes then plug back in … worked on my 2019 RAV4 Hybrid without messing with the batteries.
Technician here just encountered one of these. Another solution could be blown 7.5 under dash. (Under dash Fuse panel) It is a DCM fuse, if not blown just unplug and plug back in.
Thank you so much for this video! Just got a 2018 Sienna and this has fix got the microphone working as well as everything else the frozen DCM was blocking. You rock. It would be nice if there was another way to reboot this without disconnecting the battery. Anybody have an alternate strategy for restting the DCM?
Hello the Car Care nut. Thank you for solving issues as always. Kindly advise on how to disable the safety connect failure detected voice prompt on my Lexus ES 350 2014 anytime u turn the car ignition on. Thank you
I have the same issue 2020 Corolla not a hybrid model. I pop the hood went to the fuse box and pulled out the two fuses that said 7.5 amps on them put them right back in and everything works fine thank you so much I deliver pizza and I have to constantly call customers with my Bluetooth.
Thank you. My voice command was not hearing me. My hands free wasn’t working. No one could hear my voice. I drove to the dealer. Rather than tell me the truth… they told me to pay for the $160 per year subscription that expired after 24 month of ownership.
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.

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

Asked my service rep today .. at least there’s one guy who knows about this fix. Thanks!

Merci!

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

Which fuse di you remove? Num 1 or num 15 from engine area? Thanks in advance
@@DavideGazzotti don't remember the number but it was the one labeled DCM in the engine compartment.

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.

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

Worked like a charm on my 2020 Prius! I only disconnected the battery for a couple of minutes, that was long enough to reset the DCM.
Like all of the videos for Toyota and Lexus
Thank you for making it
Worked perfectly in under 30 min of leaving the battery disconnect .
just got this issue today and after the video I disconnected the battery see if it works. thank you for sharing!~
Too easy of a fix. Thanks for this information and may the Lord Bless you as well sir!
Nice! Thank you for this! It also solved my Remote Connect issue that also stopped working! Whew!
Did you have the prompt saying remote activation pending? I'm also trying to troubleshoot my car to see what will work instead of wasting time at the dealership
35 minutes worked! I am curious as to how often this happens.
Thank you for the simple and wonderful suggestion. May the Lord bless and keep you as well and reward you for your altruism.
Thank you very much 😊
The DCM In My car was not working
Now it's working great 👍
Genius!!!!!!!!!!!! Thanks so much. 30 minutes did it.
thank you so much for posting. worked in my 2018 toyota sienna. subscribed!
Thank you so much for this Video! It solved so much of my Problems!
Thank you so so much! This totally fixed my problem. I thought I was going to have to go into the dealer. Thank you!
My 2021 is working 💪 now thanks sir. 😊
Thank You, Thank You, Thank You! 3 year old 2019 Rav4, started trying to call no one and no one could hear me!. I was hunting for a reset of the head unit and of course just out of warrenty. Old Socket set and 40 minutes later back to normal
Fixed my 19 sienna in 2 minutes. Removed both cables and touched them together. My green light never came on though. Thanks!
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.
I'm assuming the car has to be off when you pull this fuse and put it back?
Thank u thus worked on my 2018 Toyota Sienna , and u also explained why it will would awesome video , I just kept it off for 5 mins and put it back ECU just need a reboot I assume,
Thank you sooooo much master, I fixed the issue, you saved me time and money
Go glad it that easy .on my way to Florida from. Maine. Thank you

Tk u I own a 2020 Toyota n am 75 been to service many times, same ol story they do not know or want me to.up trade.

I was praying and asking the Lord to fix this problem😭I am extremely busy with kids, hubby and parents and it was driving me crazy not being able to talk hands free in my van. I found this video the evening I prayed and it was straight from Him❤️❤️thank you so much!! And may the Lord bless you and keep you as well❤️thank you so so much. My hubby was able to fix the issue the way you said❤️❤️❤️❤️
An alternative especially for Hybrid vehicles is pull the DCM fuse located under steering wheel. Leave out for 10 minutes then plug back in … worked on my 2019 RAV4 Hybrid without messing with the batteries.
Technician here just encountered one of these. Another solution could be blown 7.5 under dash. (Under dash Fuse panel) It is a DCM fuse, if not blown just unplug and plug back in.
Thank you so much for this video! Just got a 2018 Sienna and this has fix got the microphone working as well as everything else the frozen DCM was blocking. You rock. It would be nice if there was another way to reboot this without disconnecting the battery. Anybody have an alternate strategy for restting the DCM?
Toyota is very lucky to have you and so are we. Thank you for sharing this tip.
Hello the Car Care nut. Thank you for solving issues as always. Kindly advise on how to disable the safety connect failure detected voice prompt on my Lexus ES 350 2014 anytime u turn the car ignition on. Thank you
It’s working on Toyota Corolla touring sports 2020. Thanks.
Thank you sir , able to fix in 30 mts , once again thank you
I have the same issue 2020 Corolla not a hybrid model. I pop the hood went to the fuse box and pulled out the two fuses that said 7.5 amps on them put them right back in and everything works fine thank you so much I deliver pizza and I have to constantly call customers with my Bluetooth.
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?
I'm going to try this. Thanks. Great video!
This has worked for me has well! Thank you so much!
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?
Thank you so much for this video. I just applied this on my Toyota sienna 2020 and boom!! It worked. God bless
This works splendidly! Thank you so much !!
Thank you. My voice command was not hearing me. My hands free wasn’t working. No one could hear my voice. I drove to the dealer. Rather than tell me the truth… they told me to pay for the $160 per year subscription that expired after 24 month of ownership.
Please what did you do for you to be heard via hands free. I can hear people when they call but they cant hear me
