CHAPTER 6 Diagnosis and Maintenance
This chapter contains diagnosis and maintenance information.
6.1 Diagnosis
Table 6.1 shows a test executed by the diagnostic function.
The drive has a self-diagnostic function. This function can check the basic
operations of the drive.
A test program running in the host system is required to check general operations,
including operations of the interface with the host system. (See Subsection 6.1.3.)

6.1.1 Initial self-diagnosis
When the power is turned on, the optical disk drive starts initial self-diagnosis.
Basic hardware functions are tested during initial self-diagnosis.
The hardware function test checks the normality of the basic controller operation.
This test includes the normality check of the ROM in which microcodes are
stored, microprocessor (MPU) peripheral circuit test, memory (RAM) test, and
data buffer test.
If an error is detected during initial self-diagnosis, the LED on the drive front
panel blinks.
