Data Output with the Porsche System Tester 2: DME

Main Menu

NOTE:
  • Online help can be called up with the F1 key.

Identification 

Control module identification data can be read out with this menu item.

The display shows:

Press F8 key.

The display shows:

Fault Memory 

The number of faults, the fault texts and the Porsche Diagnostic Trouble Code (DTC) are displayed in the Fault Memory menu item. In order to obtain additional information about a fault, select the fault item (reverse-video display) and press the double arrow key (>>) or the F8 key.

The following additional information on the fault is then displayed:

Erase Fault Memory 

NOTE:
  • The fault memory can be erased only if it has first been read out at least once. The entire fault memory is always erased. When the fault memory is erased, the adaptation values are also reset.

Actual Values 

Values present at the moment of the test can be read out with this menu item.

It is possible to use a filter function to select certain actual values only. In this case, not all actual values are available for selection.

Press F5 key.

The following predetermined filters then appear:

It is now possible to create your own filters in this menu item.

Press F5 key.

Mark the required actual values and press the double arrow key (>>). A field then appears where the name of the filter can be entered.

Enter the filter name and confirm.

The newly created filter then appears in the selection list in block capitals. Filters you have created can be deleted or changed.

The following values can be called up:

Fig 1: Illustrating Adaptation State Values

  1. rl - Load. See Fig 1 .
  2. n - Speed
  3. e.g. -2/1 means the second rpm range (field 2) of load range 1

1 = Field 1 has been adapted

2 = Field 2 has been adapted

3 = Fields 1 and 2 have been adapted

4 = Field 3 has been adapted

5 = Fields 1 and 3 have been adapted

6 = Fields 2 and 3 have been adapted

7 = Fields 1, 2 and 3 have been adapted

The fields have different priorities

Fig 2: Illustrating Field Priorities

  1. Priority I - Field 1/1
  2. Priority II - Fields 1/2, 2/2 and 3/2
  3. Priority III - Fields 2/1, 2/3, 3/1 and 3/3

Fields following one another can be adapted within one rpm range if the fields with priority I and II have already been completely adapted, e.g. field 1/2 can be adapted after field 1/1. Field 1/3 is blocked.

  1. A - Load. See Fig 3 .
  2. B - Rpm
  3. C - Operating status (rpm/load range) with misfire
  4. 1 - Minimum speed of range with misfire operation, e.g. 3000 rpm
  5. 2 - Maximum speed of the range with misfire operation, e.g. 4000 rpm
  6. 3 - Minimum load of the range with misfire operation, e.g. 20 %
  7. 4 - Maximum load of the range with misfire operation, e.g. 50 %

Input Signals 

Input signals of the DME can be read in by the Porsche System Tester 2 with this menu item. In this way, the function of the input signals can be assessed very quickly.

The following input signals can be read in:

Ready Status 

This menu item allows the interrogation of statuses (fulfilled/not fulfilled) of the DME. The following statuses can be checked:

To receive a ready message, allow the vehicle to warm up (engine temperature > 80 °C) and then activate all diagnostic routines which have not yet been carried out under the menu item Short test  .

Drive Links 

Drive links (actuators) of the DME can be activated by the Porsche System Tester 2 with this menu item. This permits the electric function of the drive links to be assessed very quickly.

The following drive links can be activated:

Drive Link Active 

With this menu item, drive links of the DME can be triggered by the Porsche System Tester 2 when the engine is running. This permits the function of the drive links to be assessed very quickly.

The following drive links can be activated:

Vehicle Data 

With this menu item, specific vehicle data can be read out with the Porsche System Tester 2.

The following vehicle data can be read out:

System Test 

With the system test, it is possible to detect faults in the valve lift control with both large lift and small lift.

The procedure is described under Troubleshooting.

Short Test 

This menu item allows the checking of all diagnostic paths, i.e. the vehicle does not have to be driven in order to achieve a "trip".

In the Short Test menu item, diagnostic routines can be processed which would actually only be achieved while driving and, in some cases, only after a long period.

The following diagnostic routines can be activated with the Porsche System Tester 2:

Coding 

Under this menu item, the DME control module can be coded for operation with cruise control (cruise control system).

Control Module Programming 

Four sub-menus are offered with this menu item:

  1. Read out control module (vehicle data)

    The menu item Read out control module can be used to read out data from the old control module, e.g. engine number, M numbers, etc., in order to adopt the data in a new control module.

    NOTE:
    • Only one control module at a time can be read out in order then to adopt the data in a new control module during control module programming.
  2. Program control module (new control module)
    NOTE:
    • The DME programming code and immobilizer code are required to program control modules. These codes can be obtained from the Porsche IPAS system.
    • All electrical consumers must be switched off for programming control modules.
    • Switch heater to OFF.
    • The vehicle battery must be fully charged.
    • Enter vehicle identification number and confirm.
    • Enter and confirm new programming code.
    NOTE:
    • The new programming code must match the DME programming code from the IPAS, otherwise the control module can no longer be programmed later.
    • Enter and confirm New immobilizer code.
    NOTE:
    • The new immobilizer code must match the immobilizer code from the IPAS, otherwise the control module can no longer be programmed later.
    • Select data record.
    NOTE:
    • If the data record OBD II was selected in the old control module, the tester automatically preselects "Data record OBDII".
    • The selection must then simply be confirmed. Programming commences after this confirmation.
    • When programming is complete, switch off the ignition.
    • Switch on the ignition.
    • Switch off the tester.
    NOTE:
    • In Tiptronic vehicles, the fault memory of the Tiptronic must be erased following the programming of a DME control module, as the fault "CAN timeout" is entered in the memory during programming.
  3. Program map/data

    The data record can be changed, e.g. from RoW to OBD II, with this menu item. Only the DME programming code is required.

  4. Program immobilizer code

The immobilizer code is transferred to a new DME control module with this menu item.
