Auto Stop-Start Steering Angle Issues

[OGMix376]

Thankfully I have great news.

The solution was pretty simple... take it for a spin ?

I would like to say thank you to everyone that responded, I know if I was in bigger trouble with sorting it out I was in the right place ?

Special thanks to @OGMix376 suggesting the sensors just need to recalibrate with a drive! Bang on the money. Also to @airline tech with his information regarding where everything is even with a photo, that was very informative had I had to go to the trouble of diving into that area if the drive didn't work!

I paniced when I saw the new error after changing the battery and thought I had done damage to some component, which made me afraid to move the steering wheel at all until I had more information about it, had I just taken it for a spin after replacing the battery I would not have wasted everyones time here ?

Also my Auto Stop Start is now working as it should, I just like things to work that should work, it annoys me if they don't ?

My advice to anyone down the line that stumbles upon this topic:

1) Place a 12v supply on the tails to the battery when replacing the battery in order to keep everything alive just to save any headaches and worry!

2) If after replacing the battery your steering sensor shows a fault or your reversing camera lines dont move, just take it for a spin and take some turns and even a roundabout if possible and it should come right back, mine came back after driving for 5 minutes!

3) If all else fails, post a thread in this community, you're in safe hands ?

Thanks all again, I hope I won't be back! ?

Edit: I do have one final question, when I was originally trying to fix my auto stop start "vehicle is charging" notification when I had the BAD battery, I changed the rate of charge to 90% 14.4v and the max charge to 90%, should I now change this back to the original 75% or is it better/ok to leave it at 90? Since I have a brand new healthy battery now?

Thanks again.

Happy it all worked out at minimal expense ?
Looked up the wildtrak and that thing looks pretty sweet, dare I say “wild” ?
Appreciate the acknowledgement, but you figured it out before I said anything.

TJC and Airline tech.. you guys make me feel so dumb?.
I read the posts and I’m just like “man I got so much too learn.”
But I do feel like I got es smarter from the posts.
Definitely gives me a better grasp on where I’m currently at knowledge wise (and it’s a fraction of a system that’s a fraction of the vehicle.), so I’m going to enjoy the journey for knowledge about these trucks and the tech involved….keeps me busy while I’m recovering my tweaked back from thinking I’m in my late twenties still and lifting heavy thing like it’s nothing ?

so to summarize and simplify for myself.. when I use FORscan to (post factory, factory delete) ASS, it’s recommended that I bump SOC to the 90% “sweet spot.”
Since I very much plan to keep the BMS (Battery monitoring sensor?) to provide favorable conditions for the battery and charging.?

im sure you already answered it in the post but I feel like it went over my head a bit. And I’m doubting my comprehension of this tech topic.

Strictly speaking BMS = Battery Management System and it is always active even if you unplug the Hall Effect Sensor (i.e., the Battery Management Sensor) located on the negative battery terminal.

The 5G BMS is much more dynamic, varying charge voltages all the time.

The 4G BMS samples is inputs when the truck is started and sets a voltage window that is about 0.5v wide. Once the battery begins to recover, the charge voltage drops to the low end of voltage window. If you turn off the truck and restart, the 4G BMS will again sample it inputs and reset the charge window. I have never seen it set the low end of the window below 13.5v for the 4G Ranger. The 5G Ranger BMS when running with the sensor unplugged behaves the same way, but the lower window has never drops below 13.7v.

Summary
Unplugging the sensor sets a DTC, and reverts to the older less sophisticated version that charges the battery very much like the 4G Rangers BMS does. The voltage pattern behaves exactly like the 4G Ranger, except its charge voltage is 0.2v higher.

There are a lot of other sensors involved within the 5G Battery Management System.

I've spent a year playing out a lot if different setting scenarios, and the above is the nutshell version of my efforts.

I have the ASS setting module that automatically turns off the ASS (but no longer need it).

I have evaluated the ASS/BMS Forscan settings in various combinations, comparing them to my 2005 Ranger on consecutive 40 mile drive circuits to insure that weather conditions, road conditions, and battery charge conditions are as identical as can be made. Both trucks have AGM batteries in excellent condition.

I did all of the above in an effort the extend the battery life in my 2020 Ranger after I started to see my battery deteriorate at a faster rate then I thought normal. I brought the battery back to a healthy state by using a multistage battery charger with a built in desulfator for several weeks before again driving the truck. Within a day, my battery would discharge to that 75% level, and the deterioration would begin again.

I never had this problem with my 4G Ranger so I decided to use the 4G charging system as my standard. I tried all the alternatives I could until I found the closest charge pattern to it for my 2020 Ranger. Now my battery stays healthy without needing charging/desulfating every 2 weeks.

I have even refrained from driving both for 10 days to compare the battery deterioration rates.
I still have greater dark power drain in the 5G than in the 4G, but I have significantly reduced it.

Sometimes less is more.

Thank you sir. I’ve copied this info and put it in my references folder ?

Thank you sir. I’ve copied this info and put it in my references folder ?

I had a typo which I corrected I had 5v which should have been 0.5v, and I then changed .2v to 0.2v for consistency.

Sorry!

I had a typo which I corrected I had 45v which should have been 0.5v, and I then changed .2v to 0.2v for consistency.

Sorry!

No apologies necessary, but thank you for the corrections I will make the changes in my notes.
thank you sir.
