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

The following data items are displayed, among others:

- Chassis number
- Porsche part number
- Hardware version
- Software version
- Production data

The identification data are not very informative for the user. The identification data are required in the event of problems under certain circumstances.

Fault Memory:
The number of faults, the fault texts and the Porsche fault code are displayed in menu item Fault Memory. In order to obtain additional information about a fault, select the fault item (reverse-video display) and press the >> key.

Erase Fault Memory:

NOTE: The fault memory can be erased only if it was first read out at least once. The entire fault memory is always erased.

Actual Values:
Current values can be read out at the moment of the test with this menu item.

The following values can be called up:

- RPM
- Load signal
- Air mass
- Hot film MAF
- Speed
- Voltage
- Intake air temperature
- Engine temperature
- Throttle plate angle
- Ignition angle
- Spec. air mass
- Spec. air adaptation
- Ambient pressure
- Injection time
- Exhaust temperature behind catalytic converter (value calculated by control module)
- Oil temperature
- Oxygen sensing, cylinders 1 - 3
- Oxygen sensing, cylinders 4 - 6
- Adaption value, range 2, cylinders 1 - 3 (FRA)
- Adaption value, range 2, cylinders 4 - 6 (FRA2)
- Adaption value, range 1, cylinders 1 - 3 (TRA)
- Adaption value, range 1, cylinders 4 - 6 (TRA2)
- Voltage, oxygen sensor ahead of catalytic converter, cylinders 1 - 3
- Voltage, oxygen sensor 2 ahead of catalytic converter, cylinders 4 - 6
- Voltage, oxygen sensor behind catalytic converter, cylinders 1 - 3
- Voltage, oxygen sensor 2 behind catalytic converter, cylinders 4 - 6
- Trip counter
- Time counter, substitute trip
- Camshaft position 1 deviation (cylinders 1 - 3)
- Camshaft position 2 deviation (cylinders 4 - 6)

Drive Links:
Drive links (actuators) of the ECM can be activated by the Porsche System Tester 2 with this menu. This allows the functions of the drive links to be assessed quickly.

The following drive links can be activated:

- Idle air control valve
- A/C compressor
- EVAP canister purge valve
- Engine compartment purge fan
- Secondary air pump
- Check Engine MIL
- Radiator fan
- RPM signal
(Tachometer indicates 1000 rpm)
- Fuel pump relay (fuel pump)

Input Signals:
Input signals of the ECM can be read in by the Porsche System Tester 2 with this menu item. The function of the input signals can be assessed very quickly this way.

The following input signals can be read in:

- Idle detection
- Full load detection
- A/C request
- Start enable switch
- Transmission coding
- Fuel reserve signal
- Reference mark signal

Drive Link Active:
With this menu item, drive links of the ECM 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 quickly.

The following drive links can be activated:

- Cylinder 1 injection valve off
- Cylinder 2 injection valve off
- Cylinder 3 injection valve off
- Cylinder 4 injection valve off
- Cylinder 5 injection valve off
- Cylinder 6 injection valve off
- Camshaft adjustment, bank 1
- Camshaft adjustment, bank 2

CO Adjustment:
This menu item is irrelevant for vehicles with OBD II. (CO adjustment is possible only on vehicles without catalytic converters.)

Short Test:
This menu item can be used to check all diagnostic paths; i.e. the vehicle does not have to be driven in order to realize a "trip".
In the menu Short Test, diagnostic routines can be run that would normally be possible only during a trip, and only after an extended time in some cases.
The following diagnostic routines can be activated with the Porsche System Tester 2:

- Basic mixture adaption
- Tank vent
- Secondary air
- Oxygen sensor readiness behind catalytic converter
- Oxygen sensor heater
- Oxygen sensor aging (period)
- Load detection
- Catalytic converter conversion

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:

- Operating hours counter
- Vehicle Identification Number
- Classification number
- Order type
- Country code
- Engine type
- Engine number
- Transmission type
- Transmission number
- Radio code
- Body color/convertible top color
- Interior equipment
- M numbers
- Z numbers
- Exclusive numbers

Control Module Programming:
Four sub-menus are offered with this menu item:

1. Read out control unit:
The menu item Read out control unit 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 to then adopt the data in a new control module during control module programming.

2. Program control unit:

NOTE:
- A reprogramming code and the immobilizer code are required for reprogramming. These codes can be obtained from the Porsche IPAS system.
- All loads must be switched off for control module programming.
- Switch heater to OFF.
- The vehicle battery should be fully charged if possible.

1. Input old programming code (00 00 00 [6 zeros] in the case of a new control module from the parts warehouse) and confirm.
2. Input new programming code and confirm.

NOTE: The new programming code must agree with the programming code from the IPAS, as the control module otherwise cannot be programmed later.

3. Input old immobilizer code (00 00 00 00 00 00 00 00 [16 zeros]) in the case of a new control module from the parts warehouse) and confirm.

4. Input new immobilizer code and confirm.

5. Select data record.

NOTE: If the OBD II data record was selected in the old control module, the Tester automatically assumes "data record OBD II" as the default.

Then all that is necessary is to confirm the selection. Programming proceeds after confirmation.

6. Switch off ignition after programming is complete.

7. Switch on ignition.

8. Switch off Tester.

NOTE: The Tiptronic fault memory of Tiptronic vehicles must be erased after ECM programming, as the fault "CAN timeout" is entered 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 reprogramming code is needed.

4. Program immobilizer code:
The immobilizer code is transferred to a new ECM control module with this menu item.
