Hi!
10 error code means "source key parity error". Bascly that means, that you are using incorrect key to decrypt PIN block. Try to verify terminal (source) ZPK using BU host command or KC console command (key type = 001). It should fail to generate key check value.
When HSM decrypts key from under LMK it verifies each byte to have odd parity (parity bit must be correct). If the key is decrypted with wrong key, it is very low possibility that it will have all bytes odd. The HSM returns the fail error code.
Just for info, if destination key is wrong HSM will return 11 error code.
