Had Chrysler dealer replace the auxiliary battery for me this past weekend in my 2018 Pacifica Limited and I just changed the main battery today. Still getting the stop/start unavailable error. Taking it back to get looked at by the dealer again EDIT: Nevermind! I saw in another comment thread where Bruce recommended disconnecting the power from both batteries to clear the error and that worked! I guess since I didn't replace both batteries at the same time this was a necessary step.
Engineers need to pick up a wrench once in a while maybe. Over kill to replace a battery...agree? One of their cars I believe has a battery in the fender??? Unreal man. I really miss the good old days. Great video by the way thank you.
Great video, thanks! I had all kinds of strange electrical problems -- doors, wouldn't start without multiple tries, various systems like collision warning saying they are offline, etc. Once I unhooked the aux battery, all those problem disappeared and I was only left with a non-working auto-start/stop. This is a good interim fix until the battery was replaced.
@@amandaturner1660 Storm came though and knocked out our pour about an hour after I posted that comment and we've been dealing with that so I haven't tried yet.
I would first try disconnecting the power to both batteries for ten minutes and then see if it is better. If not , then replace the batteries. Please subscribe to my channel & tell your friends. Thank you
Thanks for the video. I had to also take off the other two connecting wires in the positive terminal (red) box to get it out of the way. When putting the securing piece back in, I finally got it by reaching between the battery and the fabric insulation.
Thanks for your video about replacing the main battery. It helped me replaced mine which was bad on my 2018 chrysler pacifica limited. Auto Part said they can't touch certain vehicles as far as replacing the battery and I can see why. Thank You! 😊
Good video. A word of caution about working around a car battery while wearing a ring. A mechanic I know shorted a terminal with an open end wrench touching his wedding ring, and instantly, the flesh on his finger was burned down to the bone. Take 'em off.
ha! i just took mine off to work on wifes 2017 chrysler! wife doesn't ask me why im not wearing the ring when its on the counter anymore. im always working around the house and will take it off before any work is done! i got it caught on a 3 inch bolt holding a hammock once and that was the end of that!
And the say people are dumb on the internet. Wow thanks Men, newly married and a grease monkey. Guess I have no choice. I was thinking this very thing. Well all mechanics wear there ring, including my family of mechanics. But nope, not me no more
@@cuinican1980 I used to be an industrial maintenance tech and most of us never wore our wedding rings or any other metal jewelry on the job. They conduct electricity as well as heat and too easy to get caught on moving parts or stationary tooling. Worse yet have a heavy piece of machinery to smash or bend the ring into your flesh as Gold or silver or very soft metals.
Leave it to Chrysler. Last Chrysler i owned taught me to never own a Chrysler again. Had to remove a motor mount to replace a belt. I see Chrysler still upto no good. Had to look this up for a friend.
You have not lived life until you tried to change the battery in an Audi Q7! Under the front passenger seat! All manufacturers make things so you can’t do the work yourself! Not just Chrysler!
Why not just leave the auxiliary battery disconnected on the ground wire and don't replace it at all. It will only go bad and become a constant drain on the main battery. I hate that Start\stop system anyway.
My solution to the aux battery is to leave it disconnected. I find it to be a hazard. My van does not stop in turn lanes now but I doing have a warning light. I had a problem with the aux battery draining the main battery. I replaced the main battery first and it died again. So if you keep the aux battery hooked up, replace them both at the same time.

It is possible, the best way to be sure is to replace the battery. After disconnecting all batteries for 5 minutes , check the other electrical systems. Thanks for watching!
My stop/start is not working. It say unavailable, to service system. I have a 2018 Chrysler Pacifica. Both batteries were replaced 2 years ago. Now I have the A with the arrow circled around it with the exclamation point.
Sorry for the late reply, I moved toa new state and have not had much time for replies. You should not have to do both. You probably figured this out already. Thanks for watching!
Will this also work if the van isn’t cranking up? When I push the start/stop button it does nothing. I thought it might be the key fob but we replaced the battery in it and it still won’t crank. And it’s not showing a low battery light.
Did you have to reset anything after you put the new battery in? We were told told battery was dead and replaced it but the message for start/stop is unavailable is still coming up.
Sorry, I didn't see your comment. You need to wait about ten minutes otherwise there can be a bit of stored power the car uses to keep everything from resetting.
Had a same issue removed fuse F17 and K9 both for starter and star stop fuses started cranking alot more but empty gas tank like not starting tried another 10 minutes empty cranks then it started now its running OK just keep jump started all the time probably battery issue
On some models, I don't know if it's on models made in Canada vs made wherever else, the aux battery is not to the side of the main battery, it is in the passenger front up under the panel?
Whatever fuel had been saved by start/stop is far outpaced by the fuel burned driving to buy new batteries. You would almost think Chrysler makes AGM batteries.
Question I'm having the same issue but my battery does not have the 3 connectors it only has 2. 80 and 70 white and red, no black. Can anyone explain why?
@@brucemackenthundoesitallll4296 Thanks. I actually decided to completely remove the aux battery to make it easier to lift the main out. Not sure if my 2017 is a bit different, but it looked like it would be a real wrestling match to get the battery past that cross brace.
@@brucemackenthundoesitallll4296 yeah, always good to see how everybody else does repairs, large or small. Those Chrysler batteries cause a lot of different electrical issues as with all cars now that everything is very touchy when it comes to voltage drops. Thanks for sending and keep sharing.
You need to feel around the bottom of the battery. There is a clamp/ bolt that is holding it in place. It does not look like much but it is enough to hold the battery. Keep looking you should find it.
Thanks for this well-done video! My 2020 Pacifica installation looks the same as your 2018.
Good to hear! The more subscribers I get, the more videos I can make to help others. Thank you!

So disconnecting just the negatives on both will solve? Or both positive and negative?

Did this solve the issue? My warning light just came on this morning and I do not feel like dealing with the dealer.

Why did you relace the regular battery when it was just the start stop battery that needed replacing??
Good info, just left dealership and they told my wife to replace the back up battery it would be around 800$$$$$
We were just told this too.
WOW I hope you did not pay that.

Hi there. My start stop light is on in the dash. Both batteries are good. What do you think can be?
I would try dissconnecting both for ten minutes to let the system reset. If it is still on I would have the batteries checked by a second time.
Hmmm, so if your auxiliary battery for the auto start/stop is dead, will it affect other parts of the electrical system or just that auto start/stop?
It is possible, the best way to be sure is to replace the battery. After disconnecting all batteries for 5 minutes , check the other electrical systems. Thanks for watching!
My stop/start is not working. It say unavailable, to service system. I have a 2018 Chrysler Pacifica. Both batteries were replaced 2 years ago. Now I have the A with the arrow circled around it with the exclamation point.
So do you have to replace both at same time? My auxiliary tested ok , but store said main battery tested bad.
Sorry for the late reply, I moved toa new state and have not had much time for replies. You should not have to do both. You probably figured this out already. Thanks for watching!
I have this same exact issue. What was the solution??
Thanks this helped me out

Hey so having issues with the red box on top of battery, I tight screw all the way and the box still slides right off.
Sorry for the late reply. I sold that truck last year. I hope ytou figured it out.
Will this also work if the van isn’t cranking up? When I push the start/stop button it does nothing. I thought it might be the key fob but we replaced the battery in it and it still won’t crank. And it’s not showing a low battery light.
It is possible, hard to know until you try.
It did work. I replaced the battery and now it works.
Great to hear it is working again!
Did you have to reset anything after you put the new battery in? We were told told battery was dead and replaced it but the message for start/stop is unavailable is still coming up.
If you replaced the small battery you need to remove the power cables from both batteries to get the system to reset.
@@brucemackenthun6152 Is it supposed to reset immediately? Or am I just being impatient...
Sorry, I didn't see your comment. You need to wait about ten minutes otherwise there can be a bit of stored power the car uses to keep everything from resetting.
Had a same issue removed fuse F17 and K9 both for starter and star stop fuses started cranking alot more but empty gas tank like not starting tried another 10 minutes empty cranks then it started now its running OK just keep jump started all the time probably battery issue
Probably the battery. Please subscribe to my channel & tell your friends so I can make more video to help people save money.

In my van I don’t see the Aux battery next to the main battery. Does that mean I don’t have one? 17 Pacifica.
On some models, I don't know if it's on models made in Canada vs made wherever else, the aux battery is not to the side of the main battery, it is in the passenger front up under the panel?

Question I'm having the same issue but my battery does not have the 3 connectors it only has 2. 80 and 70 white and red, no black. Can anyone explain why?
Is it the same year?
is it necessary to unhook the aux battery if you are not replacing it?
you do need to unhook it to get the computer to reset
@@brucemackenthundoesitallll4296 Thanks. I actually decided to completely remove the aux battery to make it easier to lift the main out. Not sure if my 2017 is a bit different, but it looked like it would be a real wrestling match to get the battery past that cross brace.
How much is the back up battery
I can't remember and it probably cost more now anyway.
Auto Zone I just picked it up and replaced the AUX14 battery tonight was $99 + tax The big battery (incase your interested) is $209.
mine was still there can you help me
Did you undo both batteries for at least 5 minutes?
Today we’ll be working on a Chrysler, tomorrow we’ll also be working on a Chrysler. A Chrysler will be towed in after that and the cycle continues
Good to have repeat work with Chrysler. I hope the video helps.

My battery doesn’t move, at all. Doesn’t looks like there’s anything that’s holding it down
You need to feel around the bottom of the battery. There is a clamp/ bolt that is holding it in place. It does not look like much but it is enough to hold the battery. Keep looking you should find it.
IF you go to the 11 minute mark in the video and watch for about another minute, you will see the part that is holding in your battery
