7.3.4 LOOP TEST
At the start of the loop test, the display will show the result of
the interactive player test:
Figure 7-30
The left side of the display contains a 3-digit code, which can
have a value between 000 and 111. These values are to be
interpreted as follows:
Figure 7-31
The loop test will perform the same nuclei as the dealer test,
but it will loop through the list of nuclei indefinitely. The display
of the DVD player will display not only the three digits indicating
correct/faulty modules and the last found error code (as
mentioned, faults are detected as far as they can be within the
scope of the diagnostic software), but also a loop counter
indicating how many times the loop has been gone through.
Example:
Figure 7-32
The number after the hyphen indicates the number of times the
loop test has been performed; the 4 digits at the right side of the
display show the last error that was found when running the
loop test: the leftmost two digits of this code indicate which
nucleus resulted in a fault; the rightmost two digits refer to the
faultcode within that nucleus. For further explanation of this
error code, see list of error codes below.
