6.5.13 Check memory card interface
This diagnosis step allows the functioning of the internal memory card in-
terface to be checked. The extent of the check depends on the size of
the memory card; this is required for the check to be carried out. With a
128kB memory card the interface will only be checked to the extent of
128kB, even though the interface can address a much larger memory.
Provided that the memory card remains inserted during the whole test proce-
dure and that the mains switch is not operated the test is non-destructive, i.e.
the memory card contents will not be altered by the test.
The memory card is not checked in this test. If it is thought that there is a fault
on the memory card then the test described under section 5.4.12 should be
carried out instead of this test. That test provides information about whether
the memory card control contained in the 711 Liquino and the memory card
itself are functioning properly.
