Cyclic Redundancy Check (CRC)
22 USD 
There is a check of the control amount.
The task, to identify the standard according to which the control amount is calculated, to describe in detail the process of obtaining the control amount

B3 89 05 C0 F0 C4 FF
47 78 05 C0 C4 FF FF
ED 9A 05 C0 F0 C4 FF
45 E7 04 C0 C4 FF FF
19 E8 04 C0 C4 FF FF
My assumptions:
Numbers: (B3, 47, ED ,45, 19) is actually the CRC calculator the variable value of the constant of the constant of the constant of the constant

Good day .
I have already defined the algorithm for calculating the control amount on your data.
Add a few packages with a known control amount to check, as well as a few packages without indicating the control amount.
On packages without the control amount, I will calculate the value and give you the result so that you can check them with the known and make sure the calculation is correct.

Если вы предполагаете что это CRC-8-SAE, то не понятно в чем вопрос..
-
не сходиться вычисление
-
Это у вас J1850 ?
-
Это мне не известно
-
А есть еще какая нибудь информация? (что передает, где данный протокол применяется).
Стандартные CRC8 и 16 не подходят! -
