NOTE
Engine parameters that can be
displayed depend upon the engine
application. Six readout languages
are available and can be selected
during gauge setup. The diagnostic
gauge has a graphical backlit Liquid
Crystal Display (LCD) screen. The
display can show a single parameter
or four simultaneously (in four
quadrants). Two arrow keys
(Figure 2-10, [3]) scroll through the
engine parameter list and menu
items. The enter key (Figure 2-10, [4])
selects items. The red
(Figure 2-10, [5]) and amber
(Figure 2-10, [6]) lights alert the
operator to an active trouble code
condition.
NOTE
When viewing engine codes through
the PowerView, the SSAM will display
a four ash fault code after 30
seconds.
