Removing Display And Operator Control Unit (PCM 2)
NOTE:
- If the PCM is replaced by a new or a different PCM, read out the data with the Porsche System Tester before removal.
- The PCM has an optical waveguide
- Switch ignition off and remove ignition key.
1. Unclip switch cover from below using a plastic spatula and disconnect electrical plug connections.
2. Insert a hexagon-socket wrench sideways into the screw connection of the PCM detent hooks.
3. Close the detents (2 each side) with the hexagon-socket wrench -A- and carefully pull out the PCM.
4. For reinstallation, open the detents with the hexagon-socket wrench -B-.
NOTE:
- The number of plug connections will vary, depending on the I No. (CD changer, Bose, amplifier).
- The variant without additional audio components (external Most control units) has a jumper (output to input) connected to the optical waveguide plug.
5. Unlock and pull off antenna plugs -A, E, F-.
6. Unlock and disconnect the electrical plug connections in the order -C, B, D-.
Installing Display And Operator Control Unit (PCM 2)
NOTE:
- If a "new" PCM is being installed, the navigation module must be removed from the "old" PCM and installed in the "new" PCM.
- If the "old" PCM is being reinstalled, then begin at Step 6.
1. Before the "new" PCM is installed, unlock and disconnect the protective plug -A- for the optical waveguide.
2. Unclip the cover on the "new" and "old" PCM.
3. With the PCM removed, carefully lever out the navigation module using a screwdriver.
4. Insert the navigation module into the PCM to be installed.
5. Position the cover and press in place.
6. Push on the electrical plug connections for the display and operator control unit in the sequence -D, B, A- and the antenna plugs -A, E and F- until they are felt to engage.
7. Check that the locking tabs on the PCM are out -arrow-, opening the lock with a hexagon-socket wrench if necessary.
NOTE: Before sliding the PCM into the installation slot, make sure that the electrical leads are not trapped by the PCM or damaged.
8. Push the navigation unit into the installation slot until the locks engage on the PCM housing.
9. Connect the electrical plug connections to the switch cover.
10. Position switch cover and press in until it is felt to engage.
NOTE: After installation of a new display and operator control unit, the system must be activated with the Porsche System Tester.
11. Connect and switch on the Porsche System Tester 2.
Teaching Display And Operator Control Unit (PCM 2)
NOTE:
- If a new PCM is to be installed in a vehicle, the PCM2/CDR23 code specified in IPAS must be used.
- You can get the codes from IPAS or from your importer by specifying the vehicle identification number.
- If possible, before the PCM is removed and replaced, a read-out of the vehicle data should be obtained using the Porsche System Tester.
- During coding, the power supply for the Porsche System Tester should be guaranteed. Connect a battery charging unit to the vehicle battery.
- Symbol for the TAB key = ->|
- Instructions for the Porsche System Tester have a higher priority and are to be followed where descriptions deviate. Deviations may occur with later software versions (as of 15.0).
- The procedure given here has been structured in general terms; different texts or additions may be displayed in the Porsche System Tester.
1. Connect the Porsche System Tester to the vehicle and start the System Tester. Switch ignition on. >> to continue.
2. Select vehicle type using the cursor keys.
3. Using the >> key, move from the vehicle type to the list of control units.
4. Select 'PCM2' with the cursor keys and press the >> key.
5. In the menu 'PCM2', select 'PCM2 MMI' with the cursor keys and press the >> key.
6. Select 'Control unit replacement' with the cursor keys and press the >> key.
7. Select 'Read coding' with the cursor keys and press the >> key.
8. The message 'Coding read-out complete' will appear on the screen of the Porsche System Tester. Press the >> key,
9. Switch off ignition and replace the PCM2.
10. Switch on ignition. After replacement of the PCM2, the vehicle data is installed under the menu 'Write in coding' (see Step 7). Press the >> key.
11. System Tester displays 'Coding write-in complete'. Press the >> key.
12. Follow the instructions of the tester.
NOTE: In the case of a new PCM2, continue under Step 13.
13. In the menu 'PCM2 GW' select 'Coding' and press >>.
14. In the menu 'Coding' select 'Production mode' and press >>.
15. Select 'Production mode Off' and confirm with the F8 key.
16. In the menu 'PCM2 GW' select 'MOST actual installed components list'.
NOTE:
- In the 'MOST actual installed components list' the installed components detected are displayed.
- The installed components detected from the 'MOST actual installed components list' is compared with the 'MOST required installed components list'.
17. In the menu 'PCM2 GW' select 'MOST required installed components list'.
18. If the items in the actual list differ from those in the required list, update the 'MOST required installed components list' to the status of the 'MOST actual installed components list' by coding.
19. Quit the menu 'PCM2 GW' <<, read out the fault memory and erase if necessary.
20. Quit the menu 'PCM2' <<.
NOTE:
- Switch on the PCM2. If the PCM2 cannot be switched on, or the PCM2 switches on but no music can be heard, switch off the ignition, remove the ignition key, close the doors and lock the vehicle. Wait until the alarm system LED flashes "normal". Unlock the vehicle and switch on the PCM2 again.
- Should the PCM2 still not switch on after this procedure, proceed in accordance with the Technical Manual.
