BOOT display
3
SD-RAM check R/W check of SD-RAM
When an error is detected, the system is brought down with displaying
ERROR02 (MAIN RAM)
4
F-ROM check Hashing check of F-ROM
<At occurrence of hashing error>
Occurrence in boot system area:
The system is brought down with displaying ERROR01 (MAIN ROM).
Occurrence in main system area:
F/W update mode ( See Special Key Function (p.2-38)) starts.
5
Voltage check Voltage check
When an error is detected, the system is brought down with displaying
ERROR03.
6
FPGA configuration Configuration of PDC and HDC.
7
Device configuration decision Checking of a head and memory
8
Version information display Machine type name and main body F/W version are displayed.
At a maintenance open, revision and PDC/HDC version are also displayed.
Key input during the version information displaying starts special mode ( See
Special Key Function (p.2-38)).

1 Wiper original point Wiper original point detection (wiper motor drive)
If the detection fails, the system is brought to down (ERROR46)
If an error occurs in each
original point detection at
maintenance open,
inputting of
