Changing settings with Forscan for new H7 battery and get checksum error

[Calson]

I found a reference to changing 726-04-01 from 01XX to 02XX for the first block but nothing as to what to change the second block or set of numbers to not get a Checksum error message in Forscan. What am I doing wrong or missing?
Thanks

Shouldn't Need to make the checksum change. It will automatically fix.

FORScan tutorial is here: https://docs.google.com/document/d/1-

 

[Calson]

Whenever a UPC code is scanned or a credit card is read there is a checksum generated to indicate that all the digits were collected correctly. When a checksum fails it indicates a bad value.

I cannot tell if this is a problem with the Forscan software and so can be ignored by the user.

It can be ignored. The correct check sum will be created.

I tried entering the string for the first block and then doing a Write and got back this message so one does need the codes for both segments of 726-04-01 to change the battery from a H6 to a H7 with Forscan.

This is what I did and got the error message shown. I am using the current version of Forscan with a 2022 F-150.

@Calson
where did you get the info for the change, maybe it’s not correct?
@Livnitup any help on this?

If you were trying to write the X's then that's your problem; just put the 02 in the position indicated and don't worry about a checksum warning and continue.

What's the value in changing your battery type via FORScan? I put in an H8 but didn't change anything in FORScan.

Probably the BMS will handle it differently.

I found a second reference for the codes for the H7 battery that was XXX-1E1E-XXXX and this codes created the same bad checksum error as the other codes but the Write appeared to be successful.

My concern is that the BMS with a setting for a 70 Ah H6 battery would not charge as fully as with a setting for a 80 Ah H7 battery.

I have the new H7 battery and settings for 95% SOC for a 80 Ah battery and having a battery maintainer plugged in at night and hoping this will enable me to avoid battery drain problems in the future. I also turned off zone lighting and Wifi and Updates for the truck.
