911 Carrera Cabriolet (996) F6-3.4L (1999)
Navigation (optional/insertion)
VOCS (voice control system) (optional/insertion)
Controller Area Network (CAN) Comfort
MOST switch
External:
External amplifier (optional, Harman or BOSE)
Telephone/telematics (optional)
CD changer (CDC), (optional)
The PCM2 consists of at least two but a maximum of four MOST nodes, (Gateway, MMI and optional Navigation and VOCS (optional)), which
communicate with each other via the electronic MOST. Data is transferred outside of the PCM2 via the optical MOST.
Ring Break Diagnosis Line
Ring Break Diagnosis Line
The ring break diagnosis line is an electrical lead, which, as a stub cable, connects the individual MOST control modules in the system with one another.
The existing MOST control modules are checked at regular intervals during communication with the control modules via the electrical/optical MOST.
Single CD
Single CD
The CD player is part of the PCM2. It is used to play the audio and navigation CDs as well as to update the navigation system.
Telephone/Telematics (Optional)
Telephone/telematics (optional)
The telephone/telematics feature (optional) is available as an option and is linked to the PCM2 via the optical waveguide.
Terminating Resistors on the CAN
Control Module Function - External BOSE Amplifier
Terminating resistors on the CAN
Terminating resistors are fitted to each end of the wiring to prevent reflection on the wiring. These terminating resistors are integrated into each control
module. The interconnection prevents the resistors from being measured with the ohmmeter from the outside.
Tuner
Tuner
The tuner is part of the PCM2 (on the main board).
Voice Control System (VOCS (Optional))
Voice Control System (VOCS (optional))
The VOCS (optional) is designed as a module box which can be pushed into the PCM2 (optional). After the insertion, an electronic switch is opened and
the module is integrated into the MOST ring.
Wake-Up Function
Wake-Up Function
All control modules 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.
CAN Comfort
CAN Comfort
Communication between the 9588 Porsche System Tester II and the MOST control modules only takes place via the K lead to the instrument cluster.
The data is transferred from the instrument cluster gateway to the MOST control modules, via CAN Comfort to the PCM2 gateway, via the electrical
MOST in the PCM2 and via the optical MOST outside of the PCM2.
