Reading Out and Transferring Remote Control
Reading Out and Transferring Remote Control
General
When replacing the alarm system control module, it is possible to read out remote controls from the old control module and transfer them to the new control module. In this way, the hand-held transmitters (remote controls and transponders) can be retained. In other words, it is not necessary to change the hand-held transmitter when replacing the alarm system control module.
Requirements
- Communication can be set up between the PST2 and alarm system control module.
- The remote controls and transponders are correct and functional.
NOTE:
- When the remote control is read out and transferred, only the remote control data are read out and transferred.
- The transponder of the individual keys must be adapted to the control module. Four positions are available for this purpose in menu item "Transponder key". This function is described from step 19 onward.
Work preparation
The following information is required from the IPAS for reading out and transferring remote controls:
- Key learning code
- Immobilizer code
Procedure
1. Connect PST2 to the data link connector, and switch on the ignition.
2. Switch on the PST2, select vehicle type 911 (996) and start the automatic control module search with the double arrow key [>>].
3. After a brief search, the PST2 reports: "Fault memory reading completed".
4. Select alarm system control module and press the double arrow key [>>].
5. Select "Learning function" in the menu and press the double arrow key [>>].
6. Select menu item 'Read out remote control' and press the double arrow key [>>].
7. "Input key learning code" appears on the screen. Input the key learning code with the arrow keys [up arrow] and [down arrow] and press the double arrow key [>>].
8. "Please confirm input" appears on the screen. Check the input key learning code and press the [F7] key.
9. "Remote controls were read out" appears on the screen. Press the double arrow key [<<] twice in order to change to the control module overview. Switch the ignition off, remove the old control module, install the new control module and switch the ignition on again.
10. Press the double arrow key [>>] to set up communication with the new control module.
11. Select the menu item "Learning functions" with the arrow key [down arrow] and press the double arrow key [>>].
12. The menu item "Immobilizer" is already selected. Press the double arrow key [>>].
CAUTION:
The immobilizer code can be input only once.
An incorrect input will render the control module useless.
- In put and check immobilizer code carefully.
13. "Input immobilizer code" appears on the screen. Input the immobilizer code with the arrow keys [up arrow] and [down arrow] and press the double arrow key [>>].
14. "Please confirm input" appears on the screen. Check the input immobilizer code and press the [F7] key.
15. Select the menu item "Transfer remote control" with the arrow key [down arrow] and press the double arrow key [>>].
16. "Input key learning code" appears on the screen. Input the key learning code with the arrow keys [up arrow] and [down arrow] and press the double arrow key [>>].
17. "Please confirm input" appears on the screen. Check the input key learning code and press the [F7] key.
18. "Remote controls were transferred" appears on the screen.
19. Select the menu item "Transponder key" with the arrow key [up arrow] and press the double arrow key [>>].
20. "Input key learning code" appears on the screen. Input the key learning code with the arrow keys [up arrow] and [down arrow] and press the double arrow key [>>].
21. "Please confirm input" appears on the screen. Check the input key learning code and press the [F7] key.
NOTE: As the transponder coils must be taught individually, make sure that the allocation of the locations is the same as described under "Transponder code" on the IPAS printout (see step 22).
22. Four unoccupied positions are displayed on the screen. Position 1 is marked in black. Furthermore, the current transponder code is displayed under "Current key". This code must be stored in the same location as specified in the IPAS printout. Select position and press the [F8] key. The position is occupied with the corresponding transponder code.
23. Withdraw the key and repeat steps 19 to 22 for the remaining keys.
All remote controls have now been transferred from the old control module to the new control module, and the transponders adapted to the new control module.
- Check all hand-held transmitters for operation (lock and unlock the vehicle).
- Check all transponders for operation (engine start).
- Read out fault memory and delete any stored faults.
