Trouble shooting start stop

[ShadowsPapa]

You know, when I first starting making videos, I used to talk a lot more. But usually I'm working on my vehicle at the same time, and all of that talking cuts into work time.?? And I realized that I don't like to listen to all of that either. A 30 minute video with only about 10 minutes worth of useful info.?‍

And I'm your basic guy. No fancy music (well... sometimes I get bored and make something up??), the info that I'm spreading is usually something I've personally learned or had to fix, and if anyone has noticed, I don't ask for likes or subscribes. I'm just here to spread helpful info and some offroading in between.

I don't consider myself an expert on anything. I keep my mind in a constant state of learning. I learn from experience and I learn from others. I've learned so much from @ShadowsPapa , I feel like I can rewire a CH-47 chinook now. Lol

If you start singing Tiptoe Through the Tulips, though, I might have to delete some bookmarks........

Well I know what I’m playing with later…. Jscan- does it show %?

I'll have to dig into some of that more in depth later.
Right now I'm on restricted movement - no looking up, down, tilting my head and so on for the day and restrictions for 3 to 5 days after that. Ugh, loss of vestibular function on the left side test at 54% loss so they've got me on some therapies....... really restricting working on anything for a while, including digging under the dash to hook things up again.

Hope you get back in action quick!


I couldent find anything with IBS %?? My batteries are a month, 2 months old and read 12.4 resting voltage @40-50* 12.2v when it’s in the 20* range.

Not even close to sure where the battery temp sensor is…. But it was a warm 66* outside- I had been ideling for 5-10 minutes while in jscan but prior to this sat for 5-6 hours.

Disregard the few other selections I have shown- figured while I was in there I would check out what does what… ??

Some shops hire such dopes who have never bothered learning electrical systems - and have no experience.
Question for the masses - does any high school today even offer auto shop classes?
How many colleges offer degrees in automotive?
As far as ASE certifications - I've seen the tests.......... pretty simple, really, pure logic. Someone could get their certification and still not know what they are really doing - or more importantly, WHY or how things work. A cert doesn't mean experience. Granted, you have to get a job and work a while to have experience, but still............

So - was there a code for the IBS?
Did they use any tools to check the operation of the IBS?
I'll go ahead and answer - no to both.



Huh? The defroster issue is killing the aux battery. OK, then when the defroster issue is resolved, since that issue also caused other damage, the battery and whatever else is going on should be replaced under warranty.

One example is - water pump bearing failed - fan hit hose and radiator, destroying both. Water pump was under warranty, the other damage was caused by the water pump so is also covered. (that was on a Jeep with a mechanical fan driven by the water pump)

My point is - if they claim the defroster is causing battery issues and the defroster issue is under warranty, then anything related to it as far as damage is also covered - collateral damage.

I have no charging issues, yet, but what are they trying to say here: "Please note charge through the IBS or tie negative clamp to body/engine ground".

Compared to the old single battery system this seems quite a bit more complex. The real gotcha from what I gather is throwing your charger on the battery posts could introduce an aux battery issue.

The charging and IBS situation is exactly the same, aux battery or not.
The 4xe and many other vehicles with an IBS (invented by BMW) only have a single battery - no aux battery. The IBS is for the charging system and battery that it is mounted on.
It doesn't do anything with the aux battery. It monitors the battery health (SoH), state of charge (SoC), temperature, whether or not the battery is capable of starting the vehicle and more.
This is from Hella (along with Bosch, a big manufacturer of the IBS devices)

The IBS 12 volt sensor delivers the input for the central energy management in the vehicle. This data can be transferred directly to the cloud. If the IBS is integrated into the vehicle’s telematics system, the battery condition, for example for the entire delivery fleet, can be monitored as with DeliveryBots. Consequently, it is possible to prevent failures caused by discharged batteries.

Blind charging (connecting charger directly to the negative battery post and not the top of the IBS) screws things up as the system no longer knows the history of the battery - amps in vs. amps out and so on.
The IBS doesn't even know about the aux battery and doesn't effect how it's charged or not charged. It cares about the main/crank battery.

There's only one rule to remember when dealing with a Ford, Chevy, BMW, Mercedes, Jeep, or anything else with IBS - power in or out should go through the IBS, not under it.

I mentioned the 4xe because it's something Jeep people may be aware of - no aux battery, just one single 12 volt battery. There's an IBS on the battery.

Thanks for the clarification. So what happens when you need a jump or need to jump another vehicle? Is the IBS subjected to starter current? The other question is whether IBS data plays a role in the alternator control. If so then does the AUX battery just tag along for the "charge" getting what ever IBS directs for main battery?

Yes, that's where I see it as a weak spot. And the cheap battery Jeep sticks in there makes it worse.
The IBS has no idea how much goes into or comes out of the aux battery since technically speaking the aux battery grounds to the chassis only using the top of the IBS as a junction point.

The IBS reads current coming out of the main battery - so when the vehicle is started, it sees the starter draw out of that battery in amps.
When you jump start - whatever current comes out of the main battery for starting is registered, we don't care how much the jump pack or donor vehicle supplies.
Jumping doesn't matter - we or the IBS are only concerned with what comes out of the battery vs. what comes back in.

Impressive that it has the amp capacity to withstand and measure starter current and resolution to measure low draw conditions.
