Section - 9, Electrical

Porsche Access System (PAS)
Control Unit Replacement Requirements

Vehicle Type:
911 Carrera (997)/911 Carrera S (997)

Model Year:
2005

Equipment:
Vehicles with 315 MHz anti-theft protection (I No. 535)

Concern:
Modified PAS control units.

Information:

Modified Porsche Access System (PAS) control units are installed in the vehicles as of the dates of introduction specified below. Once parts inventory of the previous control units with the index 09 have been used up, only modified control units with the index 12 will be available to meet replacement requirements.

If a replacement control unit with the index 12 (new version) is installed instead of control unit with the index 09 (previous version), a separate antenna cable - in addition to the modified control unit - must be installed between the PAS control unit and the antenna amplifier in the A-pillar because the modified control unit has a separate antenna input.
