At main microcomputer startup, hardware (mainly LSI) is checked by a self diagnosis program.
To enter this Self-Diagnosis mode, follow the following steps:
Procedure:
1) Enter Adjustment Mode.
2) Select SELF TEST and press OK button.
3) SELF TEST screen is displayed.
4) Each code is displayed in a SELF TEST screen.
A diagnosis result is displayed with a numerical value to the right side of each code.
