[@KellyLabountyDeckerES]

Thanks so much! I I watched a vid on a 2017 and they forgot to mention to push out the 3 cables. You helped me out so I can drive my car tomorrow to work

Thanks for a great video. Just replaced mine tonight in the dark and cold. I did acquire an OBD vehicle 12V supply as a backup so as not to lose memory and programming. Everything 100% 👍

I changed the main battery, then I notice my aux batter started to smoke. Wondering if I mess up with the red part on top positive because I used spammer to unscrew it. Anyways going to change the aux battery, but don’t know if I will mess up again.

Two things. First, you're missing the air intake snorkel that inserts into the opening on the filter box, goes over the main battery, and attaches to the radiator support. Second, this van has two batteries that are connected together. You first need to disconnect the negative cable from the small aux battery when replacing the main battery. The main battery's positive cable is still live and can be shorted if you don't do this.

thanks for the info.

Does everything else he did seem accurate?

[@ruley73]

@@grimreap3r960 Yes, everything else is fine. I removed the airbox and metal bar to give myself more room to work with (both parts are easy to remove), but others might feel it's unnecessary.

I need to replace both batteries. From what you are saying, I believe that I need to disconnect the aux battery first, then disconnect the main battery second. After replacing both batteries, I'd then connect the main battery first and then connect the auxiliary battery second. Would that be correct?

[@ruley73]

@@RetArmy1SG The order in which you replace them ultimately doesn't matter. The most important thing is to remove both negative cables first and reconnect them last. If you replace one battery at a time and reconnect both cables to one battery, the other set of cables for the other battery is still live even when disconnected because the two batteries are connected together in a parallel circuit.

[@Mike_44]

If I may add something: the FSM states to first unplug the EBS sensor connected to the negative terminal, than proceed with removing the negative cable and the rest of the battery. Also, you do not reed to remove the three connectors/modules on top, just the 10mm nuts holding the plate onto the battery.

How can you test the battery sensor

@@timweb1510 I have no idea, I’m sure is in the FSM though..
