.
Data List Function
The data list items are shown in the following table.
NOTE: Data list items consist of MUT-II/III items and GST items. GST items can be accessed through the use
of a general scan tool.
NOTE: When MUT-II/III is used, MUT-II/III items appear alphabetically; then, GST items appear alphabeti-
cally. The black and white characters of the GST items are inverted from the MUT-II/III items.
