Is there a solution yet for newer 21 and up Chevrolet Suburban odometer correction? Does OBDSTAR odomaster change mileage in Suburban 2021/2022?
Here is the clue.
These models are communicating with the new CAN-FD protocol.
Suburban 2020-2022 Need luck.
Some 2021/2022 are supported and some with Spansion are not. 10 pin is supported by OBD. Some new BCM has no eeprom, Mid 2021 year. Cluster needs to be done, MCU Spansion MCU S6J334EJEE.
If Odomaster fails to correct mileage on Suburban 2021/2022 (shown in images below), update GM odometer software to V41.49 or later version.
V41.49 fixes bugs. Enter Chevy Suburban 2019- menu, and try both CAN FD and CAN FD2 ways.
You also need OBDSTAR CAN FD adapter.
FYI: GMC Yukon 2021 to 2024 are not supported yet. New Yukon Denali, open BCM and you cannot find eeprom, same on dashboard no eeprom either. Only Spansion MCU S6J334EJEE. No solution yet.
2017-2019 some managed to make it work.
