remote start dont work in the cold

[gladjes]

hey everyone. gladiator diesel rubicon 2022
got my truck last fall , EES never worked ((worked ONCE and randomly and never again), but that didnt bother me , but remote start was working well.(was hot outside)during winter time , when its cold , the remote start dosent work... does it start cycle , but never complets it... if i drive around get the truck hot, stop it and try the remote start it does work. start doing research to find out might be my auxbattery , and that you can bypass it .... so removed my aux battery , put the RED of the aux with the red of the main , did the same with the back one. .... still a no go on the remote start same thing... so i changer my main battery , for a new one. still the same thing. truck hot = works , cold truck = dosent work.....

by then spring was there so stop looking for the trouble .. but now winter is coming and kinda want my girlfriend to have her remote start.


whats going on ?

Some of this won't apply since you did the battery stuff months ago - but for future reference -

Did you charge the battery before installing it?
Did you completely disconnect the IBS (intelligent battery sensor) for a while, install the fully charged new battery, then hook it all back up?
It can take a number of hours for the IBS to re-synchronize with the new battery and decide there's enough power to do remote starts and that sort of thing.
(but since you did the battery stuff months ago, it should all be ok by now)


ESS may not have worked due to either low battery voltage, or some other issue - ESS not working can indicate other issues, so it should not be ignored even if you don't like it. It's a good indicator of issues.

If you don't drive often enough - could be the battery voltage gets low and you don't drive it enough to charge it back up.

no i did not charge the new battery prior to installing it!

no i did not disconnect the IBS (can you guide me to that one have no clue where that is)

the truck does get out each day for my girlfriend to go to work, its the main truck of the household....


should i take it out , fully charge the ''new one'' , remove the IBS stuff then reinstall it? obviously i wont know yet if it did work because it just does that stuff when its cold outside... when its hot everything is a1 except the stupid ess...


what other issue could be related to the ESS - remote start - and low aux battery ?


other question then. if the + aux on the + main and - aux on the - main. Should my ESS still be working ..? i did not remove fuse 42 , and it still dosent work.

should i go plain and simple , buy a aux battery remove my tazzer and call the dealer over the ess not working....? still under warranty...

Still under warranty? Put those cables back on the aux just like they were and make a dealer appointment.

Or!

You have a few other options. Since it is obvious you are not familiar with ESS/aux batt, I would suggest reading about it here. Follow ShadowsPapa for best results. Once you learn about how the electrical system is supposed to function, then you can start playing around.

The battery can be charged with an AGM battery charger in the vehicle. While it is charging, disconnect the IBS sensor connector. When finished charging, you can plug in the IBS.

If you had left the Aux in place and connected, you could have charged it in place by simply disconnecting the aux negative cable from the top of the IBS. The main could have been charged by keeping that aux cable disconnected and isolated and moving the charging neg cable on the main negative post.

Ess should work the way you have it now assuming the main battery is good. Pulling f42 does nothing for you since you moved the cables. The idea behind pulling f42 is to prevent the pcr from opening on a start up test or the aux. When people use that method, they disconnect and isolate the aux negative from the main negative, then pull f42. No need the way you have it.

been reading bit about that stupid ass battery for a bit now to be honest.. lol ill go look more into it via shadowpapa , found it thread about the ibs already....


at least i know i am not stupid assuming that my ESS should be working the way i did it ... ill probably plus the aux back and call the dealer.... just find it really Odd that it still dosent work

 

[Lost1wing]

If you want to play around with the electrical system, know what you are doing first. You don't want to learn the hard way and end up needing to replace the fuse array.

Get youself a good AGM battery charger. A trickle charger if fine.

Pick up a volt ohm meter. Nothing fancy but something better than a Harbor Freight give away. Don't know if you have Harbor Freight near you. Amazon has a ton of options.

So the next time you have a question relating to your batteries, you can give a better response and we can help you through it with out guessing.

oh .. dont worry i am a electricien .. ((house and commercial)) just not that great with automotive , but i have a good background.. lol

my klein multimeter says 12.30V on the poles of the battery.

i have a battery tender at home, ill look into AGM charger liek you said

If you had those tools that I just mentioned, it would save you from disconnecting Tazer and a trip to the dealer. The longer your Aux battery sits disconnected the better chance of you not being able to recover it. I am pretty confident that you were pretty careful disconnecting the aux cables and relocating them to the main. If I was you, I would charge up that aux and see if the voltage holds at 12.8 or higher. I'd still feel good about 12.6vdc. Do the same with the main. Disconnect the IBS connector and reconnect your aux if the voltage is satisfactory. Be sure reconnect the main ground at the main after reconnecting the aux cables. Then reconnect the IBS connector.

If your Aux battery voltage does not recover, at least you have it properly connected and the dealer can take a look at it. You will also have a better idea of what work needs to be done.

It’s definitely not the aux battery. Sounds like a diesel issue. I’ve never had that happen with my gasser. The only time remote start doesn’t work is if the gas is under an 1/8th tank, or if a door or the hood is open.

12.3vdc battery needs some love. But maybe not. You could have some things powered and you are reading the voltage drop. Close the door, open the hood and let it go to sleep. Then you would have a better reading. Or isolate the battery cables for a true resting voltage reading.

ESS would normally work, no matter how you did the batteries.
Even with one battery, ESS would work.

my klein multimeter says 12.30V on the poles of the battery.

12.3 is low. Should be higher.

There's electric and then there's automotive electric........ these days, not much connection.

I’d definitely just put the six battery back. Make sure it and the main are charged when isolated, separately. The install and see how it goes.

 

[ShadowsPapa]

There's over 2 dozen things that have to be just right. Also - and engine codes stored will prevent ESS from working.

the truck does get out each day for my girlfriend to go to work, its the main truck of the household....

Going out each day for a 30 minute drive won't do it. How FAR does it get driven for how long?
Commuting a few minutes to work - may not cut it, and since it's sitting at 12.3, that really sort of proves that.

Definitely not the aux, it is bypassed. He has two issues, ESS and remote start when cold. When cold, the battery voltage could drop enough to prevent his remote start issue. Working on the low battery voltage should be the priority as it could also solve the remote start when cold issue.

 

[gladjes]

for that you do are right , its small trip we mostly do...
but we did a 4 hour dive the other day , and ess never worked


yeah i know ... at least i do work on my motorcycle and old cars too .... but now theres soo many electrical/computer on those things that its pass my paygrade as a residential electrician .. ahahbutat least i do understand how to play around it lol
