Display '*' in the menu 'Control modules' and menu
'PCM2 MOST component check'.
Different required and actual installed components lists
When the 'automatic control module search' is complete, the follow-
ing display '*' appears in front of the control module description
'PCM2' in the 'Control modules' menu, as well as in the 'PCM2 MMI
function selection' in front of the entry 'MOST required installed
components list' if the 9588 Porsche System Tester ll establishes a
difference between the required and actual installed components
list and there is no fault code in one of the fault memories of the
MOST control modules.
If there is a fault code present in one of the MOST control modules,
the display '*' is only shown in the 'PCM2 MMI function selection' in
front of the line 'MOST required installed components list'.
If there is a display in the menu Control module, an existing fault
code has priority and a '#' is set.
