This checksum is 8A76. What exactly you need?

[brad123]

Hello, thank you for your answer, I need to correct the checksum because the vehicle does not start.

Use manual calculation CS in winols.

Hello everyone,
Checksum at address 01050, therefore:
0 to 01050 = 9D7B
01050 to 07FFF = ED22
CKS = 8AEC
So bit 01050 = 9D


Can someone please confirm?


Thank you
