Programming New DME Control Unit

Information 

Depending on the software version of the PIWIS Tester, a new DME control unit can be asked for the "old DME programming code". In this case, enter the code from IPAS which is also used for the "new DME programming code".

→ Prior to disconnecting the control unit, switch off ignition and remove ignition key.

→ Ensure that the power supply is not interrupted during programming.

→ Connect a battery charger with a current rating of at least → Nominal value: 40 A  to the vehicle battery.

Information 

If a new DME control unit is to be installed in a vehicle, the DME code specified in the PPN and the immobilizer code must be entered in the DME control unit.

The Power Kit code must also be entered for the Cayman R.

During DME programming, it is essential to guarantee the power supply for the Porsche System Tester. A battery charger with a current rating of at least 40 A must be connected to the vehicle battery.

The codes are available from the PPN or from your importer.

Follow the instructions on the Tester.

Later versions of the software may display slightly different text or require a slightly different procedure. The instructions you receive from the Tester itself take precedence over this description.

In some countries (currently USA, Canada) the Ready status must be obtained following a test drive or by using the Porsche System Tester after the DME control unit has been programmed. If in doubt, contact the relevant importer.

Information 

The Turbo  data record must be loaded before installing the GT2  data record. The GT2  data record can only be used after the data record without the power kit has been loaded.

The immobilizer code and enabling code from the PPN are required for the GT2  data record.

1. PIWIS Tester 9718  must be connected to the vehicle. Then start the System Tester. Switch on ignition. Press [>>] to continue.
2. Select vehicle type. Press [>>] to continue.

   Information 

   If the vehicle data cannot be read out due to a defective control unit, for example, the vehicle data will have to be written into the control unit manually when programming is complete.

   Read out vehicle data. → 247019 REMOVING AND INSTALLING DME CONTROL UNIT  - section on "Preliminary work"

3. Select DME  menu and press [>>].
4. Select Control unit programming  menu and press [>>].
5. Select Program control unit  and press [>>]. Follow the instructions displayed on the Tester.
6. Vehicle Ident. No.  must be entered, then press [>>]. Press [F7] to confirm your entry.

   Information 

   This relates only to a new DME control unit. 

   If the old  programming code and the old  immobilizer code is requested for a new control unit, 000000  must be entered for the old  programming code and 1111111111  for the old  immobilizer code.

   This procedure depends on the Tester software and the data version on the new control unit.

7. Enter the DME programming code  (PPN) and press [>>]. Then confirm your entry by pressing [F7].
8. Enter the new enabling code  (PPN) and press [>>]. Then confirm your entry by pressing [F7].

   Information 

   The Turbo  data record must be loaded before installing the GT2  data record. The GT2  data record can only be used after the data record without the power kit has been loaded.

   The immobilizer code and enabling code from the PPN are required for the GT2  data record.

9. Select the vehicle type  if required and press [>>].
10. Specify transmission type  and press [>>].
11. Specify exhaust standard  and press [>>].

    Information 

    • During programming, the electric radiator fans may start. 
12. Start programming  by pressing [F8]. The data and programming status is then loaded on to the DME control unit. Do not interrupt the programming sequence. Observe Tester instructions.
13. For the learning and adaptation routine of the throttle valve (electronic throttle), switch the ignition off, remove ignition key, insert ignition key and switch on ignition for at least 40 seconds without starting the engine. Do not actuate accelerator pedal. This completes the adaptation of the throttle adjusting unit and the programming sequence is complete.
14. In the DME  menu go to Coding  , code Cruise control present, not present.

    Information 

    The Turbo  data record must be loaded before installing the GT2  data record. The GT2  data record can only be used after the data record without the power kit has been loaded.

    The immobilizer code and enabling code from the PPN are required for the GT2  data record.

    The DME control unit must be re-programmed for the GT2  . Perform the same steps again, starting with Step  4.

    The enabling code is requested in accordance with the exhaust emission standard  if the Turbo data record is loaded and if the GT2 data record was selected during the second programming operation.

    If the vehicle data could not be read out of the old  DME control unit, the following data (see Note below) must be entered manually in the DME control unit.

    Information 

    The following vehicle data  must be entered manually into the DME control unit.

    • Vehicle identification number 
    • Order type 
    • Country code 
    • Engine type 
    • Engine number 
    • Transmission type 
    • Transmission number 
15. On the Vehicle data  screen, compare the vehicle data (PPN) with the actual vehicle and enter data specific to the vehicle if necessary.

    Information 

    If the vehicle data could not be read out of the old DME control unit for a new DME control unit, a fault entry may be stored for the PSM and PAS control units.

    Proceed as follows for the PSM control unit:

    • Switch to the PSM control unit. 
    • Select Coding [>>]. 
    • Select the required vehicle variant and press [F8] to begin coding. 
    • The model type you want may not be displayed, depending on the software version. If this is the case, erase the fault memory, exit the PSM menu, switch off the ignition and remove the ignition key from the ignition lock. Insert the ignition key again and switch on the ignition. If no further variants are displayed, the system detects the variants from another control unit. 

    For the PAS control unit >> Other control units trigger the fault C128 Communication PAS control unit. Remedial action:

    • Switch to the PAS control unit. 
    • Select Coding [>>]. 
    • Select Basic coding [>>]. 
    • Select Country version, Vehicle type, Transmission type and press [>>]. 
    • Press [F8] to begin coding. 
    • Erase all fault memories. 
16. Read out the fault memories of all control units and delete the DME control unit fault on every control unit connected to the CAN.
17. Start engine.
18. Carry out a test drive and read out fault memory again.
