I can not get the code to go away when reprogramming tire size for my tcm 23 f450 37's and level kit

May be able to get further information info here

Thanks!!
 

@ZooDad, just to confirm, is this the code in APIM to up the number of blinks when changing lanes?
If I want it to be 5 blinks would I add 2, so 4?
Not sure what the "black box" is... Can you elaborate or give me a link to go catch myself up?

Thanks again!! I'll try to get some pics uploaded tomorrow on my introduction post.
What a great community this seems to be!

ok. just did my first changes in this new truck. have used forscan before on previous trucks.

quick question, first change was to lower the tpms thresholds. when i inputed the values i wanted, 50/45, the rear changed other values in the block and then a warning came up about the checksum value not correct. i continued, everything seemed to program correctly. when i looked at the tpms values in plain english, the values i wanted are correct.

is it normal for some values to change when others are inputed and for the checksum warning to pop up?

also, the values i posted above from the as built website, match what is actually in my truck

I tried everything. I relearned the tcm 5 times and the code persisted. It did work and would drive but I had to revert to stock to get the Tom code to clear.

If all you have is the P160 with no lights, it runs fine, and speedo is where you want it, I would run it.

it is only that one code. But it throws light on the dash for service 4wd and no pre collision.

Have you done all the relearns? TCM, PCM, and AWD?

I did the pcm and the Tcm. I didn’t understand the awd needs to be relearned also. Does it read the same as the other two?

Yes, more or less. Relearn the AWD and see what happens.

Would be happy to test stuff as well. 2023 F350 6.7 HO Tremor XLT.

Would love to be able to keep the amber turn signals on as DRLS.

Thank you for your awesome work @ZooDad !

@kylant Yes when changing values in AsBuilt the last two (2) values will change. Those are the checksum to the line to make sure it is correct.

Turn Signal Flash
 

OK,
So thanks to the help of @wabba we have figured out the AsBuilt value changes for Turn Signal Flash.

The spreadsheet has been updated.
