PCM2/CDR23 911 Turbo (996)91
MOST actual and required installed components lists
All MOST control modules that are connected to the PCM2 are
entered via diagnostic tester in the 'required installed components
list'. Only the MOST control modules recorded in the MOST required
installed components list are activated. An 'actual installed compo-
nents list' of detected devices is written and saved when the PCM2
is started.
MOST component check
Note!
When there is a customer complaint or identifiable problems but no
fault code entries, firstly the 'MOST component check' is to be
selected in the PCM2 function selection menu and then the 'MOST
system check' is to be carried out.
The MOST component check can be reached via the menu PCM2
function selection. This comprises a summary of the following
check processes:
♦Data transmission check.
♦MOST system check (with engine running).
♦Ring break diagnosis (with engine running).
The MOST components check 'MOST system check' is to be carried
out when the display indicates 'unavailable MOST control modules'.
If no fault code is stored, the '*' symbol indicates a 'varying
required and actual installed components list' in the Control mod-
ules menu in front of the 'PCM2' system and in the 'PCM2 MMI func-
tion selection' in front of the selection 'MOST required installed
components list'. A comparison of these two lists can determine
faulty components.
Data transmission check
Note!
Using the function 'Reset all coding/transfer counters' all set fault
counters of all components can be collectively reset to '0'.
