CHAPTER 6 Diagnostics and Maintenance

This chapter provides diagnostics and maintenance information.

6.1 Diagnostics

Table 6.1 lists test items during diagnostics.

The optical disk drive has a self-diagnostics function. This function can check the

normality of basic operations of the drive.

To check the generation operations including the operations of the interface with

the host system, provide a test program that can run in the host system (see Section

6.1.3).

6.1.1 Initial self-diagnostics

When the power is turned on, the optical disk drive executes initial self-

diagnostics. The initial self-diagnostics tests basic hardware operations.

The hardware function test checks the normality of the basic operations of the

controller. This test includes the normality check of the ROM that stores

microcodes, microprocessor (MPU) peripheral circuit test, memory (RAM) test,

and data buffer test.

The LED on the drive front panel blinks if an error is detected during initial self-

diagnostics.
