Some damn fine troubleshooting and diagnosis! Much appreciated.

Awe, that's so nice to see your family! Thanks for including them in the video!

I stumbled across this video after buying a new battery and new starter for my malibu. These are the exact symptoms of my malibu. Thank you so mich for this!

Man wish I knew this before I bought 2 batteries and 2 alterations. Thanks

Very impressed with your diagnosis. Well done easy to understand and has solved our problem on a 2016 LTD Malibu that failed twice stop start on a freeway - VERY dangerous place to have failed.

Thx Bro great vid. I also have a vehicle well customer that i have to go and diagnose her Malibu as well, it has the battery saver mode on dash even after she replaced both batteries and the battery negative sensor, so after watching your vid , ill take a look at the Dual battery control module tmrw. THANKS AGAIN DUDE.. keep doing what you do and congrats on opening your own repair shop...

Thank you, incredible that such a small piece caused so much trouble, I no longer knew if it was my alternator or if they tricked me with the battery, thank you, excellent video

Thanks st… been having this problem for a while.. my car doesn’t start like once a month up until I jump it.. and then is ok for a little while…then does it again… I realized that turning the ac/heat all the way up also bypass the DBCM sometimes when the autostop “starts to feel weak.”

dude the is the first time i see u or this channel but i respect u and thinks ur a good person

This just happened to my car yesterday, same year model with code P305F, thanks for verifying my problem, excellent video 👍

I wish I knew this before I bought a alternator battery and starter 🤣🤣 but getting that part tomr to fix the solution thanks for this video

Thx you so much I bought a car today in the auction and the same problem as you have I have thx you for you’re video great help thx you so much

Thanks bro you helped me fix my wife’s car keep up the good work!

I have had the same problem for over a year now gonna try this. Thanks a million for the video!

You're such a life saver

Your video was helpful on my 2015 Malibu. When I got a check engine light Code P058D. Bought a new dual battery module and everything works now. No check engine now. Thanks…

Thank you very much for this video...I was able to diagnose and track down the issue as you described! Thank you!! MK

So I changed both batteries and also the battery module and nothing and at the end it was Fuse #18 battery isolator. Is locate it under the hood fuse box next to the main battery open it and replace fuse 18 you can use the fuse at spot 57 which is a spare.

Good and simple, hope you continue to build your channel

Fantastic video. Love how you work. Thx

Thanks for posting this

Thanks brother!!!, I have a similar problem and I didn't know what the problem was.

good diagnosis and straight to the point; short and sweet. thanks for sharing. i wonder if you can do a video about the starting and charging wiring diagram for 2015 chevy malibu 2.5L LT. I have the diagram but I have no clue how to interpret it from the ignition to the control modules, starter and battery etc. could you do a video explaining how it works? thanks

Awesome Job in finding problem 👏 👌 👍🏻 😀

I having the same problem now as of today. Thanks for the video.

Thanks for your informative tutorial video

Thank you very much for sharing this to all of us!!!!

You are awesome, thanks so much!!!!

Awesome thank you for the video guy

I see you didn't program it I read on some comments that a dealer had to program it Thanks for the info very helpful

Holy fuck thank you!!!!!!! I was trying to find away to diag this module for day and couldnt find nothing on shopkey for the life of me!!!!

Great video! Exactly the same problem I have. Quick question. Where did you buy the new part? I’m having trouble finding it. Thanks!

Excellent Work!!!

I jumped across two terminals and it works fine I used a 75 amp mega fuse

You know, I just received your video. And I know your voltage dropped as I had the same problem.2 yrs ago. When I finally got my key out. I looked at the cut part of key. I saw how much dirt was in the key for the ignition . I sprayed it with GM jigaloo and washed the key and ignition with the jigaloo spray. Never had a problem since. May not be related or I may have prevented it from becoming one

I am having a p305f code the dealership wanted over 700 to fix it but decided i would do it on my own. The car starts but the whole car fully resets when the stop/start engages while im out driving. Also the power im getting from acceleration is very slow idk if that is connected to this but i will be getting my part soon and installing it. Thanks for the help and ill keep you updated!

Thank you so much I never knew

Awesome bro great work all around! Thanks very much. 👍

I have a question. This is very important. Do I still have to go get the battery programmed to the vehicle?

it just had a blown fuse.circuit was back feeding into module connection causing it to read 9 volts . By replacing this control module he replaced the fuse that was in it.

Thanks for the video

Awesome job! Thanks for sharing your knowledge!

Awesome fix!!

I'm getting a P058B error code which is a faulty battery sensor module is this similar to what happened here?

Great work

Para los que no entienden ingles este man descubrio que el problema es el modulo que controla las dos baterias, el problema es que el carro a veces no arranca y si le pasas corriente si arranca por algun tiempo, el modulo se consigue en amazon o en la agencia, se llama DBCM. En los comentarios dice que ese modulo se quema muy facil y que hay que buscar la causa que es lo que lo quema.. a veces se quema inmediatamente luego de cambiarlo, es importante checar que no este flojo ningun cable de el arness antes de cambiarlo..

Hey Man. I’m having a similar issue with my 2015 Malibu. I have power when key is turned on. The engine just barely turns over like batt is low. Bat has plenty of juice. Could this bat control module cause this issue? The cat was starting and running fine day before this condition developed. Any assistance would be greatly appreciated. TY so much

Teaching people the reason for voltage drop is one the best electrical test they can use, It's great. Plus, use dielectric grease on clean connectors and fuses protects them from moisture and oxidation over time is a great practice. You can buy it at home improvement stores for $6 Joe 2022 money as well as parts stores sell the same brand, size for $9-$11.

Thank you just left my sons house

I appreciate this bro, thanks!

Thanks for sharing this information 🙏

Very helpful thank you. Mine caught on fire by the DBCM harness don't know why pretty scary

What was your reading on the auxiliary battery? Did you check that one too before you get the diagnosed?

Great video thank you.

My son has a 2013 Malibu hybrid and having the same problem but th word PARK is lit up on the dash as well but the dash still lit up and radio works but the car won’t start can you tell me what that be please and thank you

Do you need another car to jump it this way or just the cables?

I have a professional question for you. We just changed our control module out 2 months ago. Now, it’s gone out again. I didn’t know if you still did mechanic work.

having the same problem with my 2016 chevy malibu gonna try this when i get off work crossing my fingers 😭

Thanks, where do I order the part. And did you disconnect the start stop connection under hood.

Which post do you hook negative to, also if the battery in trunk is dead will that keep car from starting

My dealer wasn’t familiar with a dual battery control module. Would it be called the battery distribution engine control block?

Your video is helpful thanks :) I am having the same issue in my chevy2014, checked battery-good condition Checked grounding wires- good condition I am just unable to catch that which relay you said to swap? Double batteries? Or else ?

I have a Cruze.....2014 LT 1.4 Turbo but it looks very similar and I am having the same issue

great job men

I know this is an older video. I am having the same type of issues. If it really is the module. How would I locate this specific piece and where do I order it from? Would greatly appreciate your further assistance

Can up in post where we can order the part or something to help us get the correct DBCM part.

My check engine light is on and my battery hasn’t been able to hold a charge I’ve replace it and my alternator twice at this point. I did go to autozone and I got an error code referring to my dual battery module will replacing it fix my problems?

Where did you order that replacement piece from? I ordered one and it was a complete different configuration

Where do you buy the replacement part? I’m having trouble finding it.

I can't find this replacement part online. Can ya'll provide a link if ya'll found it?

Hello, thank you very much for sharing your knowledge, it is very illustrative, please can you help me, I have a Malibu 2013 2.5lts automatic, it gives me the P0700 generic error from the box almost a year ago it started to fail and just by isolating it or I taped the connector that goes to the box and for about 6 months it did not give me any problems, suddenly the box started to have problems, you accelerate and the engine does not respond or it makes changes out of time, I saw that the cable that goes to the chassis The motor had an intermittence, I checked it with the multimeter, I put a new ground cable from the motor to the chassis or battery, it worked correctly for a week and one day in the morning it started to fail, please can you help me or guide me to fix it and taking advantage of it, you can tell me where the second battery that the car has is to know its location. Thank you very much in advance and greetings from Mexico

were do you order the piece?

Do you have to do any programming at all after installation or is it plug n play?

Where can I get that part for the Chevy Malibu? My roommate's car his having the same issue as this one.

Had the same exact problem

Hi don’t mind my gaming account lol but I have a serious question. Ok my 2016 Chevy Malibu LTZ is stuck in service theft detection mode an won’t crank an I have tried everything an this video an it still won’t work. What do I do.

Great video

I had a question . When you replace the dual-battery module did you have to have it programmed or did it just plug in and work

Good sir I have a 2018 malibu it won't start on its on has to be jumped off but the battery is good and the alternator is good.. got a p3055 and p3056 code I need help

What if I changed it and both batteries and the light for service charging system came on again

Thanks How can i get the dbcm Im at Nigeria

I'm having the same issue where can I buy the control module haven't been able to find it?

I have 2015 chevrolet malibu and module melted is working perfectly fine no lights came on but autostart stop working do u know why did module melt I recently installed 10inch sub small could that cause the problem

Question- What would be the consequence(s) of simply leaving a jumper on those two terminals for an extended period?

Until I can afford module.will it lose power everytime I turn car off? Also I didn't see where you connected negative. Battery?

Mine read 1.0 and down is it bad? I’m having something drain my battery over night and I tested for parasitic draw by unplugging all fuses and seeing if it goes down but nothing.

What setting did you set mutimeter on to test module?

I been looking for that part online and can’t find it! Any help from someone who actually got to buy it?

What the part name you order am having this same problem mines is 2014.

Hello my frien. Could a bed DBCM cause the 12V primary battery not to charge? Or is there another module that controls the primary battery charge?

Are you located in Southern California? Maybe in the North County of Southern California?

OK, THAT WAS VERY COOL,, DO YOU DO PROGRAMMING AND ANTI'THEFT WORK THANKS FOR THE VIDEO PLEASE KEEP UP THE GOOD WORK!!!!!!!!

Where did you get the part from????

Can I just swap out the little black box by itself?????

My key is stuck in the ignition right now. My battery is fine & I changed the auxiliary one last month. I think my DBCM is bad, if I change it will my key come out after?

i am having same problem i have changed both batteries and even changed alternator and whole tune up and sometimes it turns on and sometimes it leaves me everwhere ..then 20 minutes later it turns on .where do i order the module

What if I just change the fuse amp plate would it work

Where did you find that part ?? My car is doing the same thing. It blacked out yesterday and not coming on
