Data Transfer Fault
Data Transfer Fault
If faults are detected when the data is decoded, this is known as a data transfer fault. The faults can arise when the data is encoded, when the data is
transferred through an input level that is optically too low or when the data is decoded. A fault entry is not recorded.
Display '*' In the Menu 'Control Modules' and Menu 'PCM2/ CDR23 MOST Component Check'.
Display '*' In The Menu 'Control Modules' And Menu 'PCM2/ CDR23 MOST Component Check'.
Differing required/actual installed components list
When the 'automatic control module search' is complete, the following display '*' appears in front of the control module description 'PCM2 or CDR23' 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
Porsche System Tester II No. 9588 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'.
If there is a display in the menu Control module, an existing fault code has priority and a '#' is set.
