history 1. In the Self-Diagnosis Memory, next 3
BYTE is memorized for an Error.
1 BYTE: Its Error number

8.2.4. (VHS) Self-Diagnosis History Memory Function
8.2.4.1. (VHS) Condition for memorizing of the self-diagnosis history
1. The self-diagnosis result and the supplementary data are the condition memorized just as an Error is detected.
2. There are the histories from number 1 to number 3.
3. The latest Error is memorized on history number 1,and then the old histories are shifted to the history number 2, 3.
4. Put out data from the memory number 3 by the shift is deleted.
5. If the latest Error is same with the history number 1 (2nd-latest), it is not memorized.
(The same Error number is not memorized in succession)
