LB5T-14G087 - TCU as-built

Hello, just one question: does anyone know what this parameter handles in LB5T TCU? :

754-19-04

It has changed after upgrade from -SM calibration version to -SR

Thanks is advance

It’s not defined yet per the AB info.

Can you post the TCU asbuilt?

Hello, yes sure

TCU_20230424_104245_SR.abt (2.0 KB)

I don’t see the firmware files available from Ford. Did you get the updates from UCDS or FORScan?

I do see the change on the 754-19-04 line.
-SM firmware
754-19-04 0000 0000 0078
-SR firmware
754-19-04 0005 0000 007D

Also these lines are added:
;Block 20
754H5G1000000780F04
754H5G20277F7
;Block 21
754H6G103E869
;Block 22
754H7G1000400020085
754H7G20282

I do not see new information added for the descriptors, so I’ll have to make an inquiry.

i have download the new firmware file (-SR) from the FDRS diagnostic tool for my VIN ( i have a Kuga 2022) and i have update it with Forscan (and OBD EX interface)

What i see after the upgrade from -SM, is

-SM firmware
754-19-04 0000 0000 0078
-SR firmware
754-19-04 0005 0000 007D

In previus as-built backup (-SM version) block 20-21-22 are already present.

So what you see is correct. The only change that i see is on this line but i don’t have the plain text map of this as-built data.

please, share LB5T-14G087-SR
