The PCM2 consists of at least two but a maximum of four MOST nodes, (Gateway, MMI and Navigation and VOCS (optional)), which communicate
with each other via the electronic MOST. Data is transferred outside of the PCM2 via the optical MOST.
Single CD
The CD player is part of the PCM2. It is used to update the navigation system.
Telephone/Telematics
The telephone/telematics feature is available as an option and is linked to the PCM2 via the optical waveguide.
Tuner
The tuner is part of the PCM2 (on the main board).
Unlock Counter
Interruptions occur in the system if perfect communication is no longer possible. If the relevant threshold values are exceeded, an entry is recorded in the
appropriate control module and the 'unlock counter' is incremented.
External Amplifier
The external amplifier (Harman or BOSE) is available as an optional feature and is linked to the PCM2 via the optical waveguide.
Internal Amplifier
The internal amplifier is part of the PCM2 (installed on the main board).
Wake-Up Function
All control units connected to the MOST are in sleep mode if the PCM2 is deactivated. When the PCM2 is switched on, a 'light' is switched on via the
MMI. It is reinforced and passed on by the MOST control modules that are connected.

The manual contains the diagnosis for the following system:
CDR23
General Instructions/Safety Instructions
The following points must be observed during vehicle diagnosis:
-
After the battery is connected, volatile memories must be reprogrammed. In the case of radio coding and tuning, the customer must be informed of
decoding and the deleted tuner memory.
-
Deactivate the 'automatic traffic announcement' before beginning the diagnosis on CDR23. If this is not done, the system will crash.
-
When working on the optical waveguide, please observe the instructions in assembly.
-
After troubleshooting or repairs, erase the fault memory with the Porsche System Tester II No. 9588 and carry out a test drive.
