Display * in the menu Control modules and menu PCM2/ CDR23 MOST component check

Different required and actual installed components lists When the automatic control module search is complete, the following 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 Porsche System Tester II 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 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.

CDR23 Replacement
The CDR23 is supplied as a spare part in production mode ON. Each time the vehicle is started, the stored CDR23 code is compared with the code in the instrument cluster. If they match the device is operational.

If no match is found, the device switches off after 30 seconds and the PROTECTED message appears in the display. The device is not operational. The PCM2 code must be coded.

If a match is found, the device is operational. No further checks are made while the device is connected to the vehicle electrical system.
