MKZ and Fusion Hybrid Loss of Battery SOC Display

Сообщение scn101 »

In the middle of the 2019 model year Ford and Lincoln decided to eliminate the IPC from displaying the high voltage battery's State of Charge (SOC). I have a 2019 MKZ later build and really want the SOC display. I have compared an early build VIN's "as built" data to my VIN's "as built" data and there's no difference that I can see in any module setting (except for modules that have the VIN, then there are differences in the VIN area). I was hoping I could get the SOC back using FORScan and my OBD link cable But now I believe the SOC display is actually a firmware change, and my *guess* is that it is in the IPC. Here are the VINs I've been comparing:

2019 MKZ No SOC 3LN6L5LU0KR623727 (no SOC)
2019 MKZ Yes SOC 3LN6L5LU6KR605457 (yes SOC)
My 2019 MKZ VIN 3LN6L5MU3KR627334 (no SOC)

My MKZ 3LN6L5MU3KR627334 IPC info:

I read a Fusion Hybrid forum where someone stated the following:

The "PartNo" is KS7T-JE with "S/W" KS7T-HE on Fusions with no SOC.
The "PartNo" is KS7T-JD with "S/W" KS7T-HD on Fusions that do have the SOC.

I don't know if only the IPC firmware needs to be changed (downgraded) or if another module also needs to be changed.

Not sure if this is feasible using UCDS, etc. Please let me know if you have suggestions. Thank you.

You can see the SOC battery display below to the left of the gas (petrol) fuel gauge. My Owner's Manual says I should have it!

SOrry but we not support other cables or Forscan.

But you can test it and downgrade fw use UCDS (VBF Loader):

#1: KP5T-14C026-AD
#2: KP5T-14C088-AC

Thank you for your reply. I few follow-up questions if you don't mind:

Where do I find the KP5T-14C026-AD and KP5T-14C088-AC VBF files?
Where did the 14C026 and 14C088 numbers come from?
Is restoring possible if something goes wrong?
If I need to restore, where do I find the original KP5T-xxxxxx-AE VBF part number and file for my VIN?

Thanks again.

Did a lot more reading on your website and also found my current IPC data:

IPC - Instrument Panel Control Module
Part number: KP5T-10849-AE
Strategy : KP5T-14C026-AE
Calibration: KP5T-14C088-AD

I found the strategy vbf KP5T-14C026-AE on the ucdssy.ru/calibration page but cannot locate the KP5T-14C088-AD vbf calibration. I think I should get the KP5T-14C088-AD to ensure I can return to as delivered if I encounter issues downgrading the calibration.

Any idea where I can find the KP5T-14C088-AD.vbf calibration?

Thank you. I hope the hybrid battery state of charge SOC display needs only the IPC module to be programmed and not other modules.

Is the process to flash firmware into IPC easy? Can I restore IPC to original easily if needed?

Now that I have the older two calibration files and the current calibration files as backup to restore the IPC to original if needed, what do I need next? I believe I need the UCDS programmer, can that be sourced in the USA? What is your suggestion?

I dont know more information about SOC problem, but i think need test downgrade :)
Flash firmware it easy. After maybe need reload direct configuration (and maybe not needed)

You can buy UCDS (with extended license), we ship to USA , make request in contact form

Do I need an extended licence to program VBF files? If I must purchase extended licence, do I use (deplete) tokens when programming VBF files?

For my 2019 Lincoln MKZ Hybrid, is this vehicle fully supported by UCDS? If not, what do I do?

For IPC, do I only need the two files to restore? I watched some YouTube videos that show UCDS IPC programming for a Focus that uses a SBL file and 4 other files, right now I only have two files:
Strategy : KP5T-14C026-AE
Calibration: KP5T-14C088-AD

Will programming the IPC affect my odometer mileage, VIN, or any other side effects that I should be aware of? (Yes, I'm quite nervous, I really don't want to break or brick my car!)
