Drive Links
Drive links (actuators) of the DME can be activated by the Porsche System Tester 2 with this menu item. This permits the function of the drive links to be assessed very 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)
- Tuning flap
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:
- Idle detection
- Full load detection
- A/C request
- Start enable switch
- Disturbance switch
- Transmission coding
- Fuel reserve warning lamp
- Crankshaft position signal
Status Checks
This menu item allows the interrogation of statuses (fulfilled/not fulfilled) of the DME.
The following statuses can be checked:
OBD status
- No warm-up cycle
- Warm-up cycle
- Driving cycle
- Trip
- Fault in the system
Ready status (Readiness Code)
- TWC conversion
- Fuel tank ventilation
- Secondary air system
- Oxygen sensors
- Oxygen sensor heating
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:
- 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
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:
- Basic mixture adaptation
- Fuel tank ventilation
- Secondary air
- Oxygen sensor readiness after catalytic converter
- Oxygen sensor heating
- Oxygen sensor aging (period)
- Load sensing
- TWC 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:
- Number of ignitions, area 1
- Number of ignitions, area 2
- 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 module
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 to then 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.
1. 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.
2. 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.
3. 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.
4. When programming is complete, switch off the ignition.
5. Switch on the ignition.
6. 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 characteristic 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.
