B. Trouble mode process
C. Writing to the trouble memory
In this series, the simulation (diag) allows to select whether the same trouble is written to the trouble memory when it occurs. If the DIAG simulation is
set as above, when any trouble occurs, its hysteresis is written to the trouble memory. DIAG(SIM 26-35)
0:
The same trouble as the previous one is not recorded. (Default)
