Overview of possible menus:

The following menus can be called up with the Porsche System Tester 2:

Identification

Fault memory

Erase fault memory

Actual values

Drive links

Input signals

Coding


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


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.

- 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)

Active (engine running)

- Deactivation of injection valves
- Switch of the VarioCam system, cylinders 1 - 3
- Switch of the VarioCam system, cylinders 4 - 6


Input Signals:
