For can you just send 1A DF
Can vin 1A 90
But for class 2 I can’t find any thing that works?
Class 2 vin 3C 01 to 3C 03

3C DF doesn’t seem to work

for vpw maybe try 1a 99?? the IPC's in the 03-06 trucks use 0x99 to write the mileage, don't know if they use a 1a to request it or not?

Thanks I will try that I don’t think 1A is programmed in the bcm I see 3C or 3b only will try 3C 90

Do you have a log of writing the millage assuming it unlocks first ?

I probably have a log of an IPC mileage being written, if not I can plug it in on the bench and log one.. I think the debug log of ipc hammer will even show it..

Tried 1A 99, 3C 99 and 7c 99 nothing works

Using at ma
I did find the message from the bcm to the cluster though!

And that is sent in miles an hour.

I then set my elm327 up as the bcm and sent 99999999
To cluster and cluster is now stuck at 99999999

Oops
