MOST Component Check
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:
-
MOST System check (ignition on.)
-
Diagnosis, ring break diagnosis (ignition on.)
-
Optical performance check.
-
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 modules menu in front of the 'PCM2' system and
in the 'PCM2 MMI function selection' in front of the selection 'MOST required installed components list'. A comparison of these two lists can determine
missing components.
