247019 Removing And Installing DME Control Module

Tools







Preliminary work

Preliminary work on DME control unit 987
If a new DME control unit is installed, then read out the vehicle data from the DME control unit and transfer them to the new one.

1. Connect the PIWIS Tester 9718 to the vehicle and start the System Tester. Switch on ignition. Press ">>" to continue.
2. Select vehicle type and press ">>" to continue.
3. Carry out automatic search of control units.
4. Select DME with the cursor keys and press the ">>" key.
5. Select Program control unit with the cursor keys and press the ">>" key.
6. Select Read out vehicle data (Vehicle data) using the cursor keys and press ">>".
7. The message Reading vehicle data will appear on the tester screen.
8. After replacement of the DME control unit, the vehicle data is uploaded from the Program control unit menu option.

General warning notes

General warning notes for control units

WARNING: Sudden voltage interruption of the power supply to the control module.
- Destruction of the control module.
- During 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.
- Prior to disconnecting the control module, switch off the ignition and remove the ignition key.

Removing DME control module

WARNING: Risk of damage to electronic control modules.
- If care is not taken, electrical and electronic components may be destroyed.
- Before removing the control module, switch off the ignition and remove the ignition key.


Installation Position:






1. Open rear luggage compartment lid and and lever out the clips for the carpet lining using the removal tool.


Loosening The Carpet Lining:






2. Fold over the carpet lining and unscrew the three fastening nuts for the DME control unit.


Unscrewing Fastening Screws:






3. Remove the control unit, release the connectors -A, B- and pull them off.


Releasing And Removing Connector:






4. Take out the control module.


Installing DME control module
1. Push in plug for DME control module and secure with the latching lever.


Connecting Plug On Control Module:






2. Press in connectors on the control module until they click into place.
3. Position control module and secure with the fastening nuts. M6 7.5 ftlb.


Securing Control Module:






Subsequent work

Subsequent work on DME control unit
1. Place carpet lining in position, paying attention to the fitted shape.
2. The DME control unit can be programmed using the PIWIS Tester 9718.

Programming DME control module

Programming new DME control module

WARNING: Sudden voltage interruption of the power supply to the control module.
- Destruction of the control module.
- During 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.
- Prior to disconnecting the control module, switch off the ignition and remove the ignition key.

NOTE:
- If a new DME control module is to be installed in a vehicle, the DME code specified in IPAS and the immobiliser code must be entered in the DME control module.
- The codes are available from IPAS or via the 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.
- During programming, the electric radiator fans may start.
- Depending on the software version of the PIWIS Tester, a new DME control module can be interrogated for the "old DME programming code". In this case, enter the code from IPAS which is also used for the "new DME programming code".
- 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 module has been programmed. If in doubt about this, contact the relevant importer.

1. Connect the PIWIS Tester 9718 to the vehicle and start the System Tester. Switch on ignition. Press ">>" to continue.
2. Select vehicle type. Press ">>" to continue.
Read out vehicle data.
3. Switch to the Special functions menu and perform the vehicle handover using the "F8" key.
4. In the Special functions menu, erase All fault memories by pressing ">>".
5. Carry out automatic search of control units.
6. Select DME with the cursor keys and press the ">>" key.
7. Select Program control unit with the cursor keys and press the ">>" key.
8. Select Program control module with the cursor keys and press the ">>" key. Observe the information displayed by the Tester.
9. Enter Vehicle Ident. No., ">>" confirm with "F7".
10. Enter the DME programming code (IPAS), ">>" confirm with "F7".
11. Enter the new immobiliser code (IPAS), ">>" confirm with "F7".
12. Specify vehicle type ">>".
13. Specify transmission type ">>".
14. Specify exhaust standard ">>".
15. Start Programming with "F8". The data and programming status is then loaded on to the DME control module. Do not interrupt the programming sequence. Observe Tester instructions.
16. 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.
17. In the DME menu go to Coding, code Cruise control present, not present.
18. Go to Vehicle data and, if necessary, enter the vehicle-specific data.
19. Read out the fault memories of all control units and delete the DME control module fault on every control unit connected to the CAN.
20. Start engine.
21. Carry out a test drive and read out fault memory again.
