Porsche System Tester 2
Test adapter 9616
NOTE: The test adapter must be used for all tests on electrical wiring (e.g. transmission control module - connectors/sensors).
It does not damage the plug-in contacts and facilitates location of the individual pins.
Function Selection With The Porsche System Tester 2 (Software G 50)
The following menus can be called up with the tester:
- Identification
- Fault memory
- Erase fault memory
- Drive links
- Drive links active
- Input signals
- Actual values
- Coding
Identification
The diagnosis software number and the control module part number are displayed here.
Fault memory
All faults detected by the control module are stored in the fault memory according to the respective Diagnostic Trouble Code (DTC).
Erase fault memory
The fault memory can be erased with this menu.
Drive links
Drive links can be controlled with this menu. Functions of the drive links can be determined very quickly in this way.
NOTE: Drive link diagnosis can only be performed when the selector level is in position 'P', the engine is not running and the vehicle is stationary.
The following drive links can be controlled:
- Solenoid valve 1
- Solenoid valve 2
- Solenoid valve 3
- Coolant shutoff valve
Drive links active
With this menu, the coolant shutoff valve can be actuated with the engine running.
Input signals
Input signals can be checked and read out with this menu:
- Selector lever position
- Selected gear
- Multi-function switch
- Kick-down switch
- Downshift switch
- Upshift switch
- Manual program switch
- Stop light switch
- Traction Control
Actual values
The following actual values can be read out with this menu:
- Engine rpm
