Fault History Display Method
When U-09 is selected, a four-digit box is displayed. The three digits
from the right show the fault description, and the digit on the left shows
the order of fault (from one to four). Number 1 represents the most
recent fault, and numbers 2, 3, 4 represent the other faults, in ascending
order of fault occurrence.
Example:
yyyyyy 4-digit number
 : Order of fault (1 to 4)
 : Fault description
"---" is displayed if there is no fault.
