Cayenne Turbo (9PA) V8-4.8L Turbo (2008)
The internal amplifier is part of the PCM2 (installed on the main board).
Lock/Unlock
Lock/Unlock
A lock occurs when the signal sent from the MMI via the wake-up/ is understood and answered by the connected MOST control units; this results in a
'lock (connection)'. The lock is maintained until the signal disappears, i.e. an 'unlock' occurs.
Man Machine Interface (MMI)
Man Machine Interface (MMI)
The MMI is part of the PCM2 (on the main board). It runs the gateway commands via the wake-up signal line and the distribution line diagnosis. If
control units fail, this is reported to the gateway and saved there.
MOST Actual and Required Installed Components Lists
MOST Actual And Required Installed Components Lists
All MOST control units that are connected to the PCM2 are entered via diagnostic tester in the 'required installed components list'. Only the MOST
control units recorded in the MOST required installed components list are activated. An 'actual installed components list' of detected devices is written
and saved when the PCM2 is started.
MOST Switch
MOST Switch
The MOST switch is part of the PCM2. It keeps the electrical MOST closed if no other MOST control unit is optically connected to the MOST. The
MOST switch is opened when a light signal is received from the connected MOST control units.
NOTE:
-
When the PCM2 is replaced, the coding must be performed in accordance with the connected MOST control units.
-
When the 'Switch closed' parameter is set, the switch remains closed even in existing MOST control units. Communication is then not possible.
Navigation
Navigation
The navigation module is designed as a module box, which can be inserted in the PCM2 as an option. After the insertion, an electronic switch is opened
automatically and the module is integrated into the MOST ring.
