Thank you so much for this video!!! Tesla wanted $2000 to look at my 2021 Model Y because it has been in an accident. This fixed my low voltage battery error. I'm very grateful to you!!🎉🎉🎉
Awesome video. If you don't use your tesla for days or weeks at a time especially during cold winters it goes on SLEEP MODE & my tech told me that trips the 12V battery low warning light. So Just wake it up with your App every now & then
Thank you so much, did this hack now I can charge again (21 Model Y). Saved $600 from getting a rental, still going to keep my appointment that’s 2 weeks out
Also, beware of disconnecting the fireman’s loop and the 12V battery if there’s any chance the 12V battery is dead AND you’re not replacing the battery. The 12V battery pulls in the HV contactor, and if it’s weak or dead, the car will completely die when the fireman’s loop and 12V battery are reconnected. The HV battery constantly tries to charge the 12V battery, and this action can conceal how bad the 12V battery actually is.
My model 3 never asked for the recalibration. The battery did go from 12.66 V to 13.5 volts after everything was hooked back up and not on charge. Even after charging hooked up, same 13.5 v . I did this a few days ago and the battery started out 12.6v. I pulled the battery and replaced with one out of a Miata. It worked fine. The Tesla battery measured around 6 volts😮. I put the Tesla battery on a trickle charger and reinstalled it and still got the code. Did this reset and code went away with charged Tesla battery. I have a new battery on the way. But I’ll know in a few hours or in the morning if I needed a new battery.
Batteries are cheap through Tesla, just replace the battery when the alert shows up. When the 12V battery actually dies nothing works, doors, frunk, nothing, just replace it and save everyone a hassle. Battery alone on a model 3 is $85 if you know how to put it in yourself!
Very TRUE but if your 12V battery is showing 14 .5 V & it's obvious fine (like mine is only 13 months old) out of warranty & the warning came up. I did this & now I'm good. Been 5 months I'm driving it & its all good 👍
Hey this literally just happened to me. I turned my car off normally and just entered the car then it was fine. But should i be expecting this to happen more often? Do i need to go to Tesla and replace voltage?
On the older Teslas (mine is a 2017), the 12V battery should be replaced every 3-4 years routinely to prevent getting stranded. If you have the bio weapons feature, change the HEPA filter at the same time. Get the filter from Tesla. Other aftermarket filters may not have a shroud attached like the OEM one.
I also have a 2017 MX and purchased a lithium iron phosphate replacement battery from Ohmuu that will last about 7 years or longer and a HEPA filter without the shroud because the shroud can be reused and you save money.
About 6 months later, the low voltage battery completely failed and then the error came back, but I'm thinking this was unrelated to this first error message I got.
@@monsieur420 no it never did. After the low voltage battery completely failed (it swelled up and the voltage was too low), I replaced it with a new one. It never went into any sort of limp mode though.
My model x show 67% of the battery. BUT There is warning ⚠️ “Connector on low battery voltage is not secure, Push connector tab down until locked in Place” Steps you mentioned will fix this warning??

Thank you so much worked with my model 3sr+ had a false code from when i ran out of range worked like a charm
Thanks so much man for the tutorial! Fixed my 2021 Model Y LR. False code even after a battery was replaced.
Same here. WTH
It worked. On an 2015 Model S. Let’s look how long it takes till the Information comes again. THX
Did it come back again ?
I have a same issue with S 2015
@@junaid3694yes - it worked - but it came back again - 3 times - and then the ranger changed the battery - 🔋
Thanks soo much man this worked on my 2018 Tesla model S..
That’s was a good video… my model S just had the same low voltage battery service request error pop up today. On the screen.
Don't own a Tesla, but now I know how to do this...
Excellent explanations and carefully done. Many thanks.

I have a CHG_u015. DC Fast charging disabled. Do you think if I do the same operation will salve the alert??
I'm not sure. Let me know if it does!

If you reset it the alarm and it comes back, you will need to replace the low voltage battery unfortunately.
@@AlwaysBrokenhow much does that cost
@@Dr.AustinBlanchon the battery for my 2017 MX was $181.91 from Tesla.

@@AlwaysBrokendid it go in to limp mode by chance

There is warning ⚠️

I'm not sure! These steps plus my other video should help you get to the low voltage battery terminals to check though!
Starting voltage is low
Thanks buddy.
How can I do this on a model 3?
The process would be the same, but I don't know where the components are located on a Model 3. Good luck!
My goodness but this thing is a real mouse trap. Hope you guys enjoy the nightmare.
Wish your volume was better. Just a suggestion
Thanks for the feedback! I tried to make that better on my more recent videos.
@@AlwaysBrokeni disagree, it was just fine. Don’t worry bout it lol
