<When an error is detected by diagnosis>
Detailed information is displayed under the judgment result. In detailed information, the
name of the test where an error was detected is indicated.
● How to view the error result
The following screen is an enlarged view of the detailed information indicated above.
Explanation of the detailed error information is described.
no] means that optional PCBs are not mounted.
When [no] is displayed although an optional PCB is mounted, it means that an error has been
occurring.
[NG] means that an error occurred to PCBs mounted as standard.
NOTE:
Once the tool is activated, this machine reboots after approx. 2 minutes.
After completion of the diagnosis, be sure to turn OFF and then ON the main power.

● Controller System Error Diagnosis Table
The error locations are identified according to the following table.
No Test Name Description
SN-1 MN-DDR2 Check an error between the Main
SDRAM Controller PCB and SDRAM on the
Main Controller PCB
SN-2 SM BUS MN Check an SM bus error in I2C on
DDR2 On the Main Controller PCB
Board
SN-3 SM BUS MN Check an SM bus error in SDRAM
Clock Gen (inside) on the Main Controller PCB
