Programming New DME Control Unit

Removing And Installing DME Control Unit







NOTE:
- If the DME control unit is replaced, it must be programmed using the Porsche System Tester. Thus, the DME control module can be adapted to the vehicle, the national variant and the equipment. The DME control unit is located in the radiator tank near the right fender.
- If possible, before the DME control module is removed and replaced, a read-out of the vehicle data should be obtained from the Porsche System Tester.

- The Porsche System Tester 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.

Programming new DME control module

NOTE:
- If a new DME control unit is to be installed in a vehicle, the immobiliser code specified in IPAS must be entered in the DME control unit. Testing and Inspection
- You can get the codes from IPAS or from your importer by specifying the vehicle identification number.
- During DME programming, it is essential to guarantee the power supply for the Porsche System Tester. It is essential to connect a battery charger with a current rating of at least 40 A to the vehicle battery.

- The procedure described here has been structured generally, different text or additions may appear in the Porsche System Tester.

1. Connect the Porsche System Tester to the vehicle and start the System Tester. Switch on ignition. Read out DME control unit. Testing and Inspection
2. Switch off ignition and replace DME control unit with a new unit.
3. Change to the Control unit programming menu and press >>.
4. Program control unit and press >>.
5. Observe conditions of the System Tester >>.
6. Select vehicle type and press >>.
7. Select transmission type and press >>.
8. Select exhaust-gas standard and press >>.
9. Program control unit and confirm with F8.
10. The data and programming status is then loaded on to the DME control module. Do not interrupt the programming sequence.
11. The System Tester indicates whether the control unit is programmable and the approximate programming time.

NOTE: The engine fan may start up during programming.

12. Once the DME control unit has been programmed successfully, switch to the Program immobiliser code menu and press >>.
13. Enter the new immobiliser code (IPAS), confirm with the >> key, check the code again and confirm with the F7 key.
14. When the programming period expires follow the instructions on the Porsche System Tester.

NOTE:
- In some countries (presently the U.S.A. and Canada), after programming a DME control unit, it is necessary to reach the Ready Status by a test drive and/or by using the Porsche System Tester. If in doubt about this, contact the relevant importer.
- With all DME systems, the engine must run for several minutes before the engine control module can re-learn the idle speed and mixture adaptation values.

15. For the learning and adaptation routine of the throttle (E-gas), switch the ignition on for 30 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.
16. Read out the fault memory and delete the DME control unit fault on every control unit connected to the CAN.
17. Carry out a test drive and read out fault memory.

NOTE: If faults are present, proceed in accordance with the DME 7.1.1 Manual.
