DRIVE RESIDENT DIGITAL MMC CONTROL
13.4.4 MMC Run-Time Diagnostics
While the Drive Resident Digital MMC Control is running, other tests are performed on
a regular basis with their results also reported by D2.
While the Drive Resident Digital MMC Control is running, the D2 will flash a three digit
code signal if there is an error. For example, if there is a long pause-flash-pause-flash-
flash-pause-flash-flash-flash-long pause, the code is 123.
