Removing display and operator control unit (PCM2)
NOTE:
- Always observe the general notes when working with optical waveguides.
- If the PCM2 is to be replaced by a new or a different PCM2, read out the data before removal using the PIWIS tester 9718.
- If the data cannot be read out, the new PCM2 must be coded.
1. Switch off ignition and remove ignition key.
2. Use a plastic spatula to carefully unclip the covering frame, starting from the bottom left and right.
3. Unscrew the four fastening screws.
4. Carefully pull out the PCM2.
NOTE: The number of plugs can vary, depending on the vehicle equipment.
5. Press lock on antenna plugs -arrows- and pull off antenna line -a, b and c-.
6. Release plugs -1, 2, 3, 4- one after the other -arrows- and disconnect them.

NOTE: Plug -4- must be connected first.
1. Plug in plugs -4, 3, 2, 1- in this order until they are felt to engage.
2. Push in antenna plugs -a, b, c- until the plugs are felt to engage.
3. Carefully slide the PCM2 as far as it will go into the housing in the dashboard. Make sure that the leads are not pinched.
4. Fasten the PCM2 to the dashboard with the four fastening screws.
5. Fit the covering frame and press into place until it is felt to engage.
6. Read data into the PCM2.
Reading out the display and operator control unit (PCM2)
NOTE:
- When installing a new PCM/CDR in a vehicle, the PCM/CDR code specified in IPAS should be present. Normally, the code is stored in the instrument cluster, and is read out from the PCM/CDR.
- You can get the codes from IPAS or from your importer by specifying the vehicle identification number.
- During coding, there should be a guaranteed power supply for the PIWIS tester 9718. It is essential to connect a battery charger with a current rating of at least 40 A to the vehicle battery.
- The PIWIS tester 9718 instructions take precedence and in the event of a discrepancy these are the instructions that must be followed. Deviations may occur with later software versions.
- The procedure described here has been structured in general terms; different text or additions may appear in the PIWIS tester 9718.
1. Connect the PIWIS tester 9718 to the vehicle and start it. Switch on the ignition. ">>" 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 and press ">>".
5. In the PCM2 menu, select Control unit replacement and press ">>".
6. Select Read coding with the cursor keys and press ">>".
7. The message Coding read-out complete appears on the PIWIS tester screen. Press ">>".
8. Switch off ignition and replace the PCM2. 'Removing display and operator control unit (PCM2) '
9. Switch on the ignition. Once the PCM2 has been replaced, the vehicle data is installed under the Write in coding menu (see Step 7). Press ">>".
10. The PIWIS tester displays the message Coding write-in complete. Press ">>".
11. Follow the instructions on the PIWIS tester.
Coding the display and operator control unit (PCM2)

- The procedure described here has been structured in general terms; different text or additions may appear in the PIWIS tester 9718.
- The installed components that are detected are displayed in the MOST actual installed components list.
- Compare the installed components detected from the MOST actual installed components list with the MOST required installed components list.
1. Connect the PIWIS tester 9718 to the vehicle and start it. Switch on the ignition. ">>" Continue.
2. Select vehicle type using the cursor keys.

Control module replacement - PCM2
The PCM2 is provided in active production mode in new vehicles and as a spare part. Each time the vehicle is started, the stored VIN is compared with that in the instrument cluster. Provided no match is found, the device switches off after 30 seconds and the PROTECTED message appears in the display. The device is not operational.
If a match is found, the device is operational. No further checks are made while the device is connected to the vehicle electrical system.
