2021 CORVETTE STINGRAY COUPE mileage info needed

[AvechuchoAxel]

Does any one have info about this vehicle mileage location? I removed BCM but no recognizable IC or MCU inside... Dashboard only maybe? Thanks !

I Did not tried the cluster yet...I'm looking for some tips for removal...

Thanks!

Do you think its only in BCM?
I think hours are elsewhere, no?

At the beginning I found the same as you did... but after digging a little over the rear board I found a lovely eeprom 24C16 winking at me saying...READ ME...READ ME !!!

I didn't found eeprom on Yukon Dash.

Mileage is probably stored in BCM anyways, hours in dash same as earlier years.

Haven't found the PDF for 2021 yet, but this is 2020.

Is this a cluster from Corvette C8 ???
The C7 had the km in the BCM. Did you find the km in the 2416 ?

Some 2021 with Spansion are supported and some are not. I think 10 pin is supported by OBD. The one you have, I found in 2021 TAHOE and couldn't do anything to it...Up to now.

[AvechuchoAxel]

Yes, it's a C8 ..2021

No, 2 reading with about 20 miles difference, still reading the same.

i have had issue with a 2018 suburban. I have read and write the eeprom on bench. Car wont start immo kicked in, dash on mileage display and alot more problems.
even though i have restored the eeprom same issue. i bought another used BCM and did it again very carefully and same result. i gave up and bought another one and programmed the iwth sps and sps let me enter the new mileage and save the day. '
sometimes its better use sps and it will let you do it obd very quick.

Cluster holds the mileage... I plugged it in on bench and mileage is showed on display. So, apparently no BCM programming necessary.
I asked many times CPT for confirmation on S6J334 reading/writing capabilities... no response yet. I have no clue if I'm doing a wrong connection or the programmer wont read this package 176 pin. Anyone with alternatives??? Thanks!

Looks like the BCM I had in a 2020 or 2021 Chevy Tahoe that I didn't figure out
