Functions of the central locking system

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2005 Porsche 911, 2004 Porsche 911, 2003 Porsche 911, 2002 Porsche 911, and 2001 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.

Unlike previous systems, a two-motor lock is used here.

The locked motor switches the central locking system from unlocked to locked and vice versa.

The safe motor switches the central locking system from locked to safe and vice versa.

The central locking system has three different locking conditions:

The conditions for a locking process from Unlocked to Locked are listed in the LOCKING PROCESS CONDITIONS (UNLOCKED TO LOCKED)  table.

Unlocked -> Locked

LOCKING PROCESS CONDITIONS (UNLOCKED TO LOCKED)

Triggering condition Requirements
Door lock barrel: Central locking action 2
  • Driver's door closed.
  • Pin 86 S off.
  • Pin 15 off.
  • No valid transponder (no ignition key inserted).
Radio transmitter: Central locking action 2
  • Driver's door closed.
  • Pin 86 S off.
  • Pin 15 off.
  • No valid transponder (no ignition key inserted).
Door lock barrel: Emergency locking
  • Possible at any time.
Central locking switch: Actuated to Closed.
  • Driver's and passenger's door closed.
  • Pins 86 S and 15 were deactivated for at least 2 seconds after crash unlocking.
Speed >Vgr (version coding). Driver's and passenger's door closed.
  • Pin 15.
  • Pin 86 S.
  • Pins 86 S and 15 were deactivated for at least 2 seconds after crash unlocking.
Pin 15 on (version coding).
  • Driver's and passenger's door closed.

The conditions for a locking process from Unlocked to Safe are listed in the LOCKING PROCESS CONDITIONS (UNLOCKED TO SAFE)  table.

Unlocked -> Safe

LOCKING PROCESS CONDITIONS (UNLOCKED TO SAFE)

Triggering condition Requirements
For all triggering conditions from Unlocked -> Safe for central locking system elements without Safe position (country version). See UNLOCKED -> SAFE 
(1) following central locking system radio unlocking. Following radio actuation:
  • No door was opened.
  • No pin 86 S was recognised.
  • No pin 15 was recognised.
  • No other central locking system actions were performed. Central locking system was set to Safe or Locked position before radio unlocking.
Door lock barrel: Central locking action 1
  • Driver's door closed.
  • Pin 86 S off.
  • Pin 15 off.
  • No valid transponder (no key inserted).
  • Not possible when coding central locking system elements without Safe position.
Radio transmitter: Central locking action 1
  • Driver's door closed.
  • Pin 86 S off (for at least 2 seconds).
  • Pin 15 off, not possible when coding central locking system elements without Safe position.
  • No valid transponder (no key inserted).
  • Not possible when coding central locking system elements without Safe position.
(1) re-locking time, can be coded.

The conditions for a locking process from Locked to Safe are listed in the following table.

Locked -> Safe

LOCKING PROCESS CONDITIONS (LOCKED TO SAFE)

Triggering condition Requirements
Door lock barrel: Central locking action 1
  • Driver's door closed.
  • Pin 86 S off.
  • Pin 15 off.
  • No valid transponder, not possible when coding central locking system elements without Safe position.

The conditions for a locking process from Safe to Locked are listed in the LOCKING PROCESS CONDITIONS (SAFE TO LOCKED)  table.

Safe -> Locked

LOCKING PROCESS CONDITIONS (SAFE TO LOCKED)

Triggering condition Requirements
Central locking system was unlocked, door lock barrel or radio transmitter actuated twice in 1 second, the central locking system lock is already in Safe position after the first actuation and before the second actuation is detected. As for Unlocked -> Safe
Central locking system is already in Safe position and door lock barrel is actuated to Closed twice in 1 second. As for Unlocked -> Safe
Safe position of a door is detected while pin 15 is on.
  • Pin 15.
  • At least one door in Safe position.
  • Alarm system is not activated.
Pin 86 S on. Within 10 seconds or in the inactive period after the locking command is given once.
Pin 15 on or valid transponder.
A valid transponder is detected.
IR sensor detects movement. System is in time window for movement detection.

The conditions for a locking process from Locked to Unlocked are listed in the LOCKING PROCESS CONDITIONS (LOCKED TO UNLOCKED)  table.

Locked -> Unlocked

LOCKING PROCESS CONDITIONS (LOCKED TO UNLOCKED)

Triggering condition Requirements
Door lock barrel: Actuated to Open. Not for coding variant deactivate only via radio, if alarm system is activated.
Radio transmitter: Actuated once.
  • Pin 86 S off (for at least 2 seconds).
Central locking switch: Actuated to Open.
  • Both doors closed and
  • Locking was also performed using central locking switch or
  • After locking with pin 15 on or
  • After locking via speed signal.
A door is unlocked using inner actuating mechanism.
  • Locking was performed either with central locking switch or
  • After a valid transponder is detected or
  • After locking with pin 15 on or
  • After locking via speed signal.
Crash signal
  • Pin 86 S or
  • Pin 15
Desired locked position is not achieved. Not possible with emergency function or if central locking switch is actuated.

The conditions for a locking process from Safe to Unlocked are listed in the LOCKING PROCESS CONDITIONS (SAFE TO UNLOCKED)  table.

Safe -> Unlocked

LOCKING PROCESS CONDITIONS (SAFE TO UNLOCKED)

Triggering condition Requirements
Door lock barrel: Actuated to Open. Not for coding variant deactivate only via radio, if alarm system is activated.
