Thank you so much for posting this -- I had replaced my aux battery and was still running into issues, even though the aux battery was healthy and fully charged! You're a lifesaver, saved me from having to go to the dealership to get this done and saved me some $$$
Followed your instructions for correcting the Start/Stop Service Required battery replacement. I followed each step you recommended and other than having a little trouble disconnecting the two wires the rest of the battery installation went smoothly. I waited 30 minutes before reconnecting everything and the all is working fine with no more Service message issue. Many thanks for taking the time to help Volvo owners save a few bucks.
Great and simple explanation of procedures. I followed all instructions. The reset was over an hour while my son took me to the battery store and running some errands. After installation everything went smoothly well. Thank you so much.
Your welcome
Thank you for explaining WHY you unplug things or wait for x amount of time before proceeding and what may happen if you don't!! Make more videos like this so we can do the simple repairs ourselves instead of getting run over by the dealership. Keep on keeping on!
Glad it helped
Thanks for this video. This is really helpful for resetting the system which I didn't know that when I watched other CZcams video. I actually removed the rear batter connector (negative) for more than 30 min., and then system was reset. I couldn't see the alarms anymore. All good here.
Glad it helped
Thanks for sharing all this great detail and taking the time to make this. It was great, but I couldn't remove the 2 cables / connectors on the front of the box that houses the support battery for the life of me. It was to the point that I was fearing I would damage them if I kept it up. Not sure if this will always work, but I found a Volvo Tech's post on Reddit who suggested simply leaving the car locked for 8 hours. Sure enough, the error disappeared after I did that. Maybe I got lucky, but I figured I'd share for the benefit of anyone else struggling with those cables.
Your correct those cables could be hard to remove. And yes you can leave your vehicle locked for over 8 hours and should fix this. By disconnecting those connectors it makes it faster
Thanks for the video! Old battery gave only 2 volts... I had hard reset for 20 mins, no error messages afterwards. Thanks from Finland! 😊
Your welcome
Start/stop error will show after driving. After hard reset you need to drive at 20km/h+ to test it. If you replace battery without disconecting ECU and main battery you need to wait 24 hours and drive car for fer km to make message disapear.
You shoud say in video to people they MUST buy Start stop battery. Same size of this are normal motorcycle batteries and this batteries will die after one year or less...
I put 15AH to my V60 II, working well and can hold car for about 1hour in stop mode.
Your video helped me a lot. Thank you so much, getting a new aux battery from the dealer tomorrow.
Your welcome
Cool! Thanks for that video. Quick and dirty, but super efficient.
Just changed my battery using this super helpful clip, Thank you!!!
Your welcome
Thanks for the video, worked perfectly! Just beware not to do the same mistake as I did and break the “Transmission Inverter Control Module” when disconnecting the main battery… that’s the bit that connects the main battery negative terminal to the harness. Replacement part is over $100….
Sorry to hear that how did that happen
Thanks!! Great walkthru of the steps.
Excellent your video and istructions !! have done this procedure when replacing the support battery on my XC 90 2018 and resulted very well. Thank you very much !!1 Carlos Roberto from São Paulo Brazil
Your welcome my friend
Thank you sir for this!
Trying it as we speak😊
My 2019 v60 showed message about auxiliary battery needing service as well as power steering malfunction and parking sensors not available. All this connected to the auxiliary network...the thing is the battery i changed still had 12.6v. Not so bad, but the positive nut was loose. Maybe causing bad connection...
🫡 your welcome, any loose connection will cause all these messages to appear
Awesome explanation. 5star!!
Thanks , don’t forget to subscribe
Thanks so much for the very informative video. I have a 2021 S90 b4, less than 2.5 years old, at 22,000 km. Dealer told me the battery is at 60% life. No any reminder message so far. Didn’t realize the “support battery” and the “back battery” issue back then. May I ask,
- the battery check at the dealer usually means the support battery?
- or if my back battery (48v?) is really dying down, what warning message would I and would I still be have some time for the replacement before it drop dead on me?
Thank you for taking your time to read and I really appreciated it if I get your reply.
Excelente. Funcionou perfeitamente no meu XC60 T5 2018. Muito agradecido.
😃
Thank you for this instructions. Very useful. I have a question please. My start/stop is working erratically and also have sometimes the message of driving assistance temporarily not working. Should I have to unplug the connectors too or just replace the battery? Also when I removed the cover of the battery I saw the cable heads are full of some sort of build up out of the battery but is not rust. I cleaned it up but I am not sure is that is enough. Thank you!
😎Thanks a million for posting this..... Perfect
No problem 👍
Worked perfectly. Thank you
Your welcome glad it did
Great Video. Thanks! Question: My service department wanted $450 in labor to do this on top of the $154 battery cost. I asked "why so much" and they said because software had to be installed to make this new Aux battery work? It this true? I didn't see anything about software in your video. Were they just talking about the hard reset and calling it "software"?
This battery is charging when car is running? Like the big battery? Should have 12v on positive and negative cables?
100% solution for this thank you
What if I tested the support battery and it’s over 12V. I proceed the disconnecting of all cables and main battery to perform a hard reset and the massage still comes up?
Thanks so much man, it worked perfectly!
You're welcome!
Same comment from me. The big difference for resetting is to disconnect all cables/battery. This is a crucial step when replacing the support battery.
Thank you for posting this
You're welcome
Just have this light on , look like easy to fix , really help 😊😊
Glad it helped
i took my XC90 to, 2 different garages and they couldn’t figure out the problem, there error was testing the Support battery while it was still connected to the rear battery, so it still showed 12v. which the rear battery was, after watching your video, i removed the support battery, tested it, it was 6.8V got a new battery today, and all is good!! 👌
Glad it helped
Exactly the same happened to me...kept on checking the aux battery voltage while it was still connected, showed 12 v something, after watching this video went back removed the battery and the voltage now was 9 something....thanks for all the help.
@wrenching Mafia - you have vids on replacing end gapes on rear sunroof seal, replacing weatherstirp, and cleaning the drains. seems like a common thing with these Volvos's I have a 2016....
Yes I’ll make a video
Mine has a wet headliner even under light rain. I would appreciate that video very much. Typing while sitting and waiting for the 20 minutes to reconnect the batteries on my 2018 S90. Great video, btw! Hope it solves my problem. Thanks!
Thanks for your video, I wish I can have this tools and I guess you made it look easy in your video, have same problem with same message but first time dealer said all is good , but now it’s been for than 4 days message on the my dash and it will cost $400 plus to replace with the dealer. Any advice!! Or feedback.
Thanks again
You can buy yourself some inexpensive set of tools and performed this job, nothing complicated. With these easy instruction you will be able to perform the job, you can contact me in my email you have any other questions wrenchingmafia@gmail.com
If I need to replace the main battery in the rear of the XC90 would I use the same system reset procedure you showed here?
Yes
Perfect!!!
Glad it worked
Changing the auxiliary battery sooon, after noticing the start stop feature coming up, few days ago the main battery light came on could a bad auxiliary battery cause the main battery to act up as well?
Best thing to do is to test both batteries
Are you going to loose your settings programmed in the Sensus like navigation, radios, driver profile, etc. after disconnecting the 12V batteries?
That stuff should not erase. Your clock time should also adjust automatically
So I have a 12v battery light on as well as the start stop… although sometimes the 12v battery light won’t come on and the next day it’ll come back on. When it’s on the only different thing I notice is the AC not blowing strong enough. When the 12v battery is off it’ll blow normally. I’m not sure if this is an alternator issue.. the car has its days when the 12v battery wants to come on and times when it comes off. Please help me. 2017 Volvo xc90… I do notice sometimes when I do a very quick start off the red light with the 12v light on the dash is the light will come off but then it’ll come back on when I’m not pushing the car as I did from the start. Please help
Any help?
Thanks for this fantastic video showing us how to do this. I just came back from the dealer to run the annual maintenance of the car and I reported that the start stop works randomly and I have a message on and off that the power steering assistance had reduced, which apparently can be connected with stop/start support battery issues. I don't have any message saying Start/Stop Service required though. Anyway, dealer says that they need to replace support battery and cables? Is this right? I was thinking about buying a new battery and replace it myself following your instructions but if new cables are required I would need to take the car to the dealer. I would appreciate your advice, please.
cables are easy to replace they just get corrosion. nothing complicated but if not comfortable with performing repair it’s best for a tech to do the repair 👨🔧
@@WrenchingMafia thanks, I am perfectly comfortable doing that if I know how to. Do you have any video showing how to do this?
@@ROKAPENA honestly you dnt have to replace wires. Just spray some battery cotton spray and use a metal brush to remove the corrosion and you should be good
@@WrenchingMafia thank you
Hi!
One of the battery cover bolt seems stuck in there and I cannot remove even with a torque gun. It keeps spin freely. Please help!!!
It’s messed you toy need to cut it off
Hi, I tried it twice but still have the "A with a strike through" at the 500 RPM position. So no start stop, but no other warnings. It's a 2016 XC90 . I called the dealer and they said it needs a software upgrade to recognize the new battery. And the software is not free! It's $100 for software and $100 labor. Sounds strange. The battery is a new OEM volvo battery and shows 13V in DMM. THanks
These dealers are crooks.
When you disconnect all batteries for 15+ minutes to hard reset, do you not have to enter some radio PIN or any non-sense like that to make all the systems work again? Thanks in advance for the answer.
No it should not affect anything but reset the system
Have you ever had the cover not come off? The bolts on mine won't come out and the dealer is trying to charge me for cutting it off. It's the original support battery in the car.
Yea it happens specially if it’s rusted in there
Is there any type of software update that might be necessary? Dealership is telling us we need to do the support battery and a software update...
Yes software is required if it’s not up to date
Thanks for uploading this! I had my support battery replaced about 7mos ago because I was getting to start stop msg and now it's started again few days ago. Could it be the same thing or the main battery?
Did you put an aftermarket support battery that will be my first question
I'm not sure I went to a mechanic would it show on the paperwork? They said they normally replace both batteries but I the support battery was pretty expensive so I only did that one I just don't want them to tell me it's the main battery and not be honest thank you
Any tips on removing the two plugs? 1:01
Queeze hard
Does it work for my V90 CC D5 as well? I have the same problem.
Yes
And it worked pretty well!
I recently had power steering failure light and there was no power steering after starting my 2019 s60. I turned the car off and then back on and no warning light and all was fine. The dealer told me it was likely the auxiliary battery failing and replacement would be $350. Do you agree?
Yes common problem. I said you can buy it yourself and do the job. Straight forwards job
I tested the aux. battery and it read 12.45 . Perhaps the power steering light was a fluke as it hasn’t happened again since?
@wrenchingmafia, I noticed that you changed 32238082 battery with 30659531. Which one would you advise to install in V90 T5 2020 if the price is the same?
Parts get updated so it will be same battery’s with updated part number
@@WrenchingMafia I see that 30659531 has Cold start capacity 180A, and 32238082 - 170A, so it is not the same. In my car 31652780 is installed, and it seems that this model is discontinued (and substituted with 32238082)
@@WrenchingMafia but anyway thanks you for the video, it will definitely save me 100+ euro ;)
@@PavloKyryliuk glad it helped
@@PavloKyryliuk so it will be the 180en one then
Hi - I have a 2018 XC90. The auto start/stop is not working always. Sometime it works and most time it is not. I ran with Volvo service center almost 2 years now and there are still not able to fix it. One time they replaced support battery and still issue not solved. Two weeks before they said everything looks good and they are not sure why it is not working always. any suggestion or advice?
This can be an issue with the main battery. In order for the start stop to work it needs to meet a lot of criteria to be able to work. Have you checked your main battery, if it’s in a slow state of charge this can cause it too. If you read your owners manual it will give you a detail list of criteria’s for start stop to function
@@WrenchingMafia They checked main battery too and said that looks fine as well. Though, the car meets all criteria for start/stop. Still I doesn't work all the times. It works sometimes but don't know what criteria it met. Should I hard reset myself like you described in that video?
How can I open the back door if my cx90 don't have batery?
You can put jumper cables under good at jumping points and should be able to unlock trunk hatch
I don't care for the stop/start they put on some vehicles now.
Great Video Though👍
Yeah I agree
After 6 years this showed in my 2017 XC90, replaced a new aux battery yesterday but the display is still showing up? Did yours disappear after you changed it?
Did you performs the reset
@@WrenchingMafia oh....how do you reset?
@@topherpab6998 watch the whole video it will show you
@@WrenchingMafia yes. Thanks.. I didn't do a hard reset but just noticed that if you just drive it, it will disappear. Just saw it now.
@wrenching mafia dealer said the battery is at 50% capacity....but I dont' have the start stop/warning. Do I still need to complete a hard reset?
I would and fully charge that battery that is low
@@WrenchingMafia so it should be replaced or can be charged(Support battery)? THANKS!
@@Benji-vz4iw how old is the support battery
@@WrenchingMafia unsure. i'll have to check it out...I have a 2016 XC90
@@Benji-vz4iw if it’s anything pass 2-3 years I would replace it to be honest
Hello
When we do hard reser for 15-20min with negative cable can we make some damage on the car? Mauby some code gone lost or so..
Thanks many many time.
No damage
Thanks.
Can i use motocycle EXIDE AGM 12V 10ah 150A or only original volvo? It's to exensive😢
@@igorvasic1391 I believe it’s a 170 and 180 minimum or else it might still trigger light
@@WrenchingMafia 170 cca
@@igorvasic1391 yes 👍🏽
Great video sir.
Sorry but I absolutely detest Auto start/stop especially like the volvo one which cannot be permanently shut off.
If the secondary battery is disconnected will this disable start/stop but leave the car running normally without issue or damage?
This is the only thing putting me off the beautiful XC90 B6.
It depends, some model are running without any issue, but newer ones will have problem with powerstearing, aircon, parking sensors and others.
For the last few weeks, my wife has been using the start/stop service light as a way to not have to turn the auto start/stop feature off every time she gets in the car. I drove her car this morning and saw the warning message. When I asked her about it, she told me that she didn't bother mentioning it to me because everything else worked fine except the auto start/stop that she hates anyway. 😆
@@joshuaychung 😂😂😂 Fantastic! My kind of lady. 😘 ⬅️ For you wife not you😉
My 2020 had a setting to permanently turn it off. Is that just the case for the XC60 I have? I’d think the XC90 would be the same.
If I don’t replace this will this affect my overall drivability? Or just only affect the stop start feature? I don’t care for the stop/ start feature.
It won’t affect drive ability it will only affect the start stop function
@@WrenchingMafia awesome, thanks for the prompt reply. The first chance I get I’m going to disconnect that battery. I’m tired of disabling that feature every time I start the car. I just replaced the starter at 100k.
@@MY-pj8cd anytime of you ever have anymore questions let me know. I have a lot of knowledge on these cars
@@WrenchingMafia
Most definitely, I will. I’ll start by asking about the oil. Stupid question, but under the hood says Castrol edge professional 5 30. Manual says the aforementioned and also I think 0 25 grade. Sometimes I can’t get to the dealer and these oil change places use 0 25 Castrol. I’ve had this car since Feb of this year. I want to use the right oil and stick to it.
@@MY-pj8cd I believe in your manual it will also show what oil has to be use depending on climate temperature. A lot of it might have to do with the climate environment you might be in. A suggestion is to call your local dealership and just verify with them and see what they are using there.
Where do I purchase the replacement
You can go to dealership or local battery store
Just had mine replaced under warranty after 30000 km
Is that same process with a XC 60?
Yes
Thanks a lot👍🏻👍🏻👍🏻👍🏻👍🏻🤩
@@bigd4727 your welcome BigD
Glad to hear it’s the same process for the xc60 as mine just appeared!!!
@@davidgrinzi8353 glad to hear
Can the support battery be recharged?
For the most part no, once it has a bad cell it will not go to a full state of charge
Thank you. I bought a new one and will replace it this weekend.@@WrenchingMafia
@@burningmanmike glad to hear, make sure you disconnect main battery and both connectors to front of support battery to reset system
Just recently bought a 2017 xc90 t6 and thinking this may be the issue with intermittent power steering message and then yellow non blinking check engine light? The start stop, we usually turn off, but when it’s on, it doesn’t always work….so will go ahead and replace both batteries and see if it works. Watched several of your videos and you seem to be most helpful! Keep at it Sir!
For a dealer, this guy is pretty rough with the car. I constantly wonder why plastic covers have broken tabs and don't fit they they should when I get it back from the dealer, and now I know why. Additionally, any quality mechanic knows that you remove the ground terminal first when disconnecting a battery....as well as putting the ground on last when installing so you avoid the arc, which you saw in the video, which can cause all kinds of electronic issues in these newer cars. There's just no pride in doing things correctly these days, it just another job to get done
