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 handheld transmitter when replacing the alarm system control module.
Requirement:
- Communication can be set up between the PST2 and alarm system control module.
- The remote controls and transponder coils 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 coil 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 in the menu and press the double arrow key [>>].
5. Select Learning functions from the selection list and press the double arrow key [>>].
6. Select menu item Read out remote control and press the double arrow key [>>].
7. The following message appears on the screen:
"Input key learning code".
Input the key learning code with the arrow keys [down arrow] or [up arrow] and press the double arrow key
8. The following message appears on the screen:
"Please confirm input".
Check the input key learning code and press the key [F7].
9. The following message appears on the screen:
"Remote controls were read our". Press the double arrow key [<<] twice 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 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.
- Input and check immobilizer code carefully
13. The following message appears on the screen:
"Input immobilizer code".
Input the immobilizer code with the arrow keys [down arrow] or [up arrow] and press the double arrow key [>>].
14. The following message appears on the screen:
"Please confirm input.
Check the input immobilizer code and press the key [F7].
15. Select menu item Remote control transfer with the arrow key [down arrow] and press the double arrow key [>>].
16. The following message appears on the screen:
"Input key learning code".
Input the key learning code with the arrow keys [down arrow] or [up arrow] and press the double arrow key [>>].
17. The following message appears on the screen:
"Please confirm input.
Check the input key learning code and press the key [F7].
18. The following message appears on the screen:
"Remote controls were transferred"
19. Select menu item Transponder key with the arrow key [up arrow] and press the double arrow key [>>].
20. The following message appears on the screen:
"Input key learning code".
Input the key learning code with the arrow keys [down arrow] or [up arrow] and press the double arrow key [>>].
21. The following message appears on the screen:
"Please confirm input".
Check the input key learning code and press the key [F7].
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 below.)
22. Four unoccupied locations are displayed, and location 1 is marked in black. Additionally, the transponder code is displayed under current key. This code must be stored in the same location as specified in the IPAS printout.
Select the locations and press the [F8] key - the location will be allocated the associated 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 handheld transmitters for operation (lock and unlock the vehicle)
- Check functioning of all transponder coils (engine start)
- Read out fault memory and delete any stored faults.
