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!
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.
It wasn’t an interior fuse?
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
Woah! Gonna try this as my right speaker stopped working as well.
This totally work too thank you !!
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.
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.
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
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.
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.
Did this fix your dcm? I'm having trouble with my sos button being active
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.
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.
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!!!!
Fixed in less than 20 minutes, detached my negative connection like you said. Thank you. Definitely beats going to the dealer
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
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!
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!
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.
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!! 🏅👍🏽
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!
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.
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 👍
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
This problem was driving me NUTS!! I thought it was an issue with my Apple Car Play. Thanks for the info!
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!
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?
This worked (the unplug the battery thing)!!! Saved us $$$$$ from having to go to the dealer.
I have a 2019 Prius limited and it work, remove the negative for 30 minutes and boom!!! Everything is good! You are the man!
This totally works! Had an estimate from the dealer for $385 as the starting point for replacing the microphone. You are a lifesaver!
Thanks a lot. As suggested by others I removed the DCM fuse from the interior fuse box of a RAV4 MY19 and It worked.
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.
Thanks, removing the DCM fuse worked for me, required no tools.
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.
@@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!
Don’t see any DCM fuse in engine compartment or in interior compartment on my 2016 Hybrid RAV4
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.
.
I tried the removing the 7.5 fuse for the DCM and it worked like a charm.
Thank you, thank you!!!!!
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.
Totally disagree. Easier to remove the batt neg connector than that fuse, unless you have an special fuse removal tool.
THANK YOU!!! Everything you said was exactly correct! We fixed my Sienna in less than two hours!!!
I just filed a complaint with the NHTSA about the issue-what if we had needed the SOS button??
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 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.
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.
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.
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.
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
EDIT: Disconnected the battery overnight, and it DIDN'T WORK! By the way, this is a 2018 Prius 2 Eco. Next: take it to my trusted Toyota dealership. 😞
It never fails, when I have an issue with my car, I can come to you and find a way to fix my issue. I'm going to try this tomorrow with my car. Thanks!
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!
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.
Where is the DCM fuse? My mic is not working after replacing the amplifier.
2015 Lexus IS 250
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.
I’m sitting at the Toyota dealership right this minute trying to get this fixed right now.
my right side front speaker and microphone didn't work and unplugged the battery overnight made EVERYTHING WORKS AGAIN!! Thanks so so so much!!😁😁😁
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 !
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!
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?
On Yaris dated 2020 it worked !! The problem was the DCM freezing . Very happy about it
Toyota Sienna Users
Remove DCM (7.5 fuse) from the engine bay. Leave fuse off for 2mins max and reinsert the fuse. Turn vehicle on and make a call or check for SOS green light. 👍🏽
This worked for me😁2018 Toyota sienna
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
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!!
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
35 minutes worked! I am curious as to how often this happens.
Your tip saved me! I disconnected my battery for 30 minutes. I put it back. My car is fine now.
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?
Fixed...saved me several hundreds of dollars (which was my estimated repair cost from dealership) and time. Thank You!!!!
2017 prius 4. Although the only time is seems to be a problem is voice recognition. Calling after hanging up... or just sometimes. Also, it asks if you want to call using the home number... when there is only one number... (not the mic.) It also seems to run slower than ever.
Thank you for your video. Just tried this and it fixed my issue within the hour on my 2019 Toyota Corolla hatchback.
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?
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!
30 minutes later and it works again. Thank you for the video.
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!
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!
Worked perfectly in under 30 min of leaving the battery disconnect .
It worked! I disconnected the battery on my Sienna over night and BAMM! Thank you! You save me some headache and $$
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,
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...
Fixed my 19 sienna in 2 minutes. Removed both cables and touched them together. My green light never came on though. Thanks!
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.
I’m having this problem now with my 2013 Tacoma…people can’t hear me well…does anyone know a fix for that?
You are a lifesaver man! This video saved me potentially hundreds of dollars!
Your explanation was great. It worked, thank you. I have the cell phone audio back.
Wow I was getting excited until I found out my 2007 Tundra Crew Max wasnt covered here. The bluetooth mic sucks, misunderstands or cant understand my voice commands. I even swapped for a diferent radio, seemed a little better at first, but now it does the same thing...can you help me?
The Toyota RAV4 hybrid has two batteries. Are you talking about disconnecting the 12 volt in the back?
I have this problem exactly on my 2019 nx300 but that green light is on. I will try the battery and hope that works. I did the phone delete and nothing.
Bluetooth and hands-free works normal, dcm reset complete, headunit software up to date. The person receiving the call hears a electric toothbrush sound using iPhone or Android phones or land-line phone? Your repair suggestion greatly appreciated.
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.
Just purchased a 2018 Camry Hybrid and the display says microphone not connected. Tried unplugging battery but no luck.
Question is does the headliner have to come down to get to the microphone or does the upper console piece come off?
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
If disconnecting the battery over night can the radio lose all its settings and presets. Plus here a good question water coming in around the roof rack and running down the B and C pillars a shorting out all of the wiring harnesses. Right now the price is over $16.000 bucks because of tiny little washers that’s suppose to stop water from coming in. This is 2020 Rad4 premium. Toyota is not standing behind the product with is still under factory warranty.
I have the same problem with the 2016 Toyota Camry XLE. Do I use the same fix?
Thank you! This worked on my Lexus NX!
How do you do this for a hybrid car? I’ve tried watching other videos and I still don’t know.
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.
I deleted my negative cable from my battery for 8hrs and it came on green but once I tried to connect my phone the green light went off again
AMD, I want to report this fix also works for Lexus. This worked on my 2015 RX 350 that was plagued with Bluetooth problems. Also, 30 minutes is insufficient. I tried it for 30 minutes and it did nothing, but an overnight disconnect worked!
Great Video!! But I just got my 2019 RAV4 Limited back from the dealer, this past Wednesday. They replaced the Telephone Transceiver Assembly, it was covered under the Warranty. 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?
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
So when you reset DCM does light on SOS button supposed to stay green even after subscription expired,
So my 2020 Toyota Camry is doing the same thing people can’t hear me on my Bluetooth but I can hear them. I disconnected the negative side of the battery over night and hooked it back up and nothing…. Can you please lmk any more tips or anything else I can do? What do you think my problem is? The green light on the sos isn’t working either.
Thank you very much 😊
The DCM In My car was not working
Now it's working great 👍
just got this issue today and after the video I disconnected the battery see if it works. thank you for sharing!~
I tried disconnecting the battery for a couple hours, as well as pulling the DCM fuse out for the same amount of time. Hooked everything back up and still not working. Any other ways to get the mic to work?
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 did this and only left it unplugged 30 minutes. Thanks for the tip.
Deleted all phones, disconnected negative terminal overnight, replaced the dcm fuse under dash and did a system update via Toyota website through the usb port. Speakers sound great when playing music via bluetooth but when on a call, only get sound through the drivers dash speaker and it is very distorted on both the callers end and mine. Still searching for a fix.
Tried disconnecting the battery for 2 hours and removing the DCM fuse & re-connecting it in my Lexus RX 2022 model, still having the same issue. What can have gone wrong, how to diagnose it?
Hello my dear, It looks great way to fix the issue.
I just bought USA corolla 2020 LE(used one)
I have 3 issue, when i press handsfree call botton or when radio is on it says "microphone is not connected".even bluetooth in setting is grayed out and camt add blutooth(add device is not working).
Regarding SOS light the big Red remains red after start the car but there is a small green light beside the right which is switch on.
When i press SOS speaking command say" its try to connect to connect if you want cancel press it again".
2- with door open the front head lamp deast work even door open option has been pressed.
3- the passenger side speaker door speaker not work.
I have tried your trick and also pulled out DCM/myday 7.5 fuse still doent turn to green and not work!!!.
What are your ideas about the issue.
Appreciate so much if you answer
Sincerely,
Farman
Question: will I be able to open my trunk the following morning to reconnect the battery? 2013 Avalon hybrid with only key or cabin button entry.
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)?
Hi! Yes that seems to be the case here. Further diagnosis is needed in this case
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
Hi! There’s a software update not to resolve this issue if it’s reoccurring. Also disconnecting the battery shouldn’t cause any issues
