Control Unit Function

Modifying coding

CAUTION:
- Risk of damage to backrest if automatic lumbar control is performed after unlocking the vehicle with hand-held transmitter
- After replacing the control module, deactivate the required lumbar position in the "Modify coding" menu item.

The following settings can be selected in the menu and coded using the "Modify coding" menu item:










Communication with alarm system control module
The two control modules seat memory and alarm system communicate via a signal lead. This makes it possible to adjust the mirror and seat positions via hand-held transmitter. If required positions of the rearview mirrors and driver's seat are assigned to a hand-held transmitter, the rearview mirrors and driver's seat move to these positions as soon as the vehicle is unlocked with the hand-held transmitter.

The communication lead between the two control modules can be checked for signs of an open circuit using the Porsche System Tester II 9588. To do this, proceed as follows:
1. Connect the Porsche System Tester II 9588 and switch on the ignition.
2. Select Seat memory control module.
3. Select Alarm system interface level in the Input signals menu item.
4. Press the Locked/Unlocked button on the hand-held transmitter.

The switch position on the Porsche System Tester II 9588 is closed briefly.

NOTE: The adjustment function via the hand-held transmitter is correct only if the radio code and the transponder code of a hand-held transmitter are each stored at the same position in the alarm system control module.
