Part 2

Function display and audible checkback
The operating state of the central locking system is fed back via the "Door locked" output and by corresponding activation of the interior light (signals 1 to 3). The operating state of the alarm system is also indicated during the inactive period by the alarm readiness display (display types 1 to 6). It is indicated exclusively by the alarm readiness display at the end of the inactive period. Displayed system faults are always current faults. Previous system faults entered in the status memory have no influence on the function display.



























Display type 6 (OFF).
The LED is not switched on.

In addition, the checkback of faults and of the standard status is performed with signal 3 at the interior light output. An audible checkback via the alarm horn output also takes place at the alarm control module, together with a visual checkback via the outputs for the direction indicator lights.

Signal 1:
The outputs are triggered once.
On time 50 ms

Signal 2:
The outputs are triggered twice.
On time 1, 2 50 ms
Off time 200 ms

Signal 3:
The outputs are triggered once.
On time 2500 ms

These functions can be switched on and off with the Porsche System Tester II No. 9588, depending on the country variants. The times are freely programmable.

Assignment of the display type of the alarm readiness light to the operating state.










If a control command is issued via the hand-held transmitter, this is confirmed with display type 4 for the duration of the operation. This display has priority.

Teaching hand-held transmitter

General
Up to four hand-held transmitters can be adapted to the control module. The hand-held transmitter is used to operate the central locking system and to open the luggage compartment (front lid). Furthermore, the stored seat, mirror and lumbar support positions are set when the vehicle is unlocked with the hand-held transmitter. The immobiliser function is also controlled by the integrated transponder.

Work preparation
The following information is required to teach the hand-held transmitter:
- Key learning code from IPAS
- 24-digit code no. (see bar code label on key grip)
- If the key is lost or the hand-held transmitter is faulty, all keys still in the customer's possession will be required.

NOTE:
- During maintenance work, please bear in mind that the transmission frequency of the hand-held transmitter is different according to the country of use. The corresponding reception frequency is printed on the alarm system control module. This reception frequency is either:
- 433 MHz with M-number M534 or
- 315 MHz with M-number M535; refer to the allocation table for country coding.

Procedure
1. Connect the vehicle keys and the new hand-held transmitter and insert in the ignition.
2. Connect the Porsche System Tester II No. 9588 and switch on the ignition.
3. Select "Alarm system" in the menu and press the double arrow key [>>].
4. Select "Learning function" in the menu and press the double arrow key [>>].
5. Select "Transponder key" in the menu and press the double arrow [>>] key.
6. "Input key learning code" appears on the screen. Enter the key learning code using the arrow keys and and press the double arrow key [>>].
7. "Please confirm input" appears on the screen. Check the entry and press the [F7] key to confirm the input.
8. Differentiate between "teaching an additional hand-held transmitter" and teaching for a "lost or faulty" transponder.
8a. Teaching an additional hand-held transmitter
Select a free position (1, 2, 3 or 4) with the arrow key [down arrow] and press the [F8] key.
The transponder code is now saved to the selected position. Note the position of the new transponder code.

8b. Teaching in the case of a lost or faulty hand-held transmitter

CAUTION:
Risk of theft due to the lost hand-held transmitter
- It is essential to delete the transponder code of the lost hand-held transmitter as described in step 8 b).
- It is essential to delete the radio code of the lost handheld transmitter as described in step 12 b).

NOTE: The adjustment function of the seat, mirror and lumbar positions 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.

In this case, it is first necessary to identify and delete the stored transponder code of the lost or faulty hand-held transmitter. All remaining vehicle keys are required for this purpose because all transponder codes are erased during the deletion function.

The transponder code of the vehicle key is displayed under "Current transponder".

Press [F3]. "All codes will be deleted" appears on the screen; confirm with the key. F3 F7

Insert the vehicle key with the new hand-held transmitter into the ignition lock and switch on the ignition. Establish communication between the Porsche System Tester II No. 9588 and the control module. Select the position (1, 2, 3,or 4) with the arrow keys [up arrow] and [down arrow] and press the [F8] key. The transponder code of the first hand-held transmitter has now been taught. Remove the key and repeat the process with the remaining hand-held transmitters.

9. Press the double arrow key [<<], select the "Remote control" menu item and press the double arrow key [>>].
10. "Input key learning code" appears on the screen. Enter the key learning code using the arrow keys [up arrow] and [down arrow] and press the double arrow key [>>].
11. "Please confirm input" appears on the screen. Check the entry and press the [F7] key to confirm the input.
12. Distinguish between lost and faulty transmitters and an additional hand-held transmitter for the radio code.
12a. Teaching an additional hand-held transmitter:
Select the same position (1 to 4) as for the transponder key and press the [F8] key.

12b. Teaching in the case of a lost or faulty hand-held transmitter:

In this case, it is first necessary to identify and delete the stored "radio code" of the lost or faulty hand-held transmitter. The remaining hand-held transmitters are required for this purpose.

Press the locking button on the hand-held transmitter and then insert the vehicle key into the ignition lock, switch on the ignition and re-establish communication with the control module.

The radio code of the hand-held transmitter that was last used to unlock the vehicle is displayed under "Current radio code".

Compare this radio code with the radio codes at positions 1 to 4. This comparison allows you to identify the position of the lost hand-held transmitter (radio code) as one radio code is ultimately left over at positions 1 to 4.

Insert the vehicle key with the new hand-held transmitter into the ignition lock and switch on the ignition. Establish communication with the control module. Select the identified position with the arrow keys [up arrow] and [down arrow] and delete the radio code with the [F3] key. Then press the [F8] key.

13. Carefully enter the 24-digit code number using the arrow keys [up arrow] and [down arrow] and press the double arrow key [>>].
14. "Please confirm input" appears on the screen. Check the entry and press the [F7] key.
15. Now the hand-held transmitter is taught. Go back to the "Learning function" menu item, remove the key and switch on the ignition again. Once the key has been removed again, the handheld transmitter is ready for use. Check that the hand-held transmitter functions correctly.

Identification
The part numbers and the system designation (I32/I48) can be read out under the "Identification" menu item.

Controlling interior lights
The interior lights are not controlled directly by the door contacts. The interior lights are switched on:
- When the central locking system is unlocked with a key or via radio transmitter.
- When the doors are opened.
- When pin 86 S is switched off.

The interior lights are switched off (doors closed):
- 30 seconds after the central locking system is unlocked with a key or via radio transmitter.
- 30 seconds after the last open door has been closed and pin 15 and pin 86 S are switched off.
- When both doors are closed and pin 15 and pin 86 S are switched on.
- After the last open door has been closed and pin 15 and pin 86 S are switched on.
- When the central locking system is actuated to Locked or Safe via hand-held transmitter or door lock barrel and both doors are closed.
- When the last door has been closed, if one door was still open when the central locking system was actuated to Locked or Safe via hand-held transmitter or door lock barrel.

The interior lights are switched on and off dimmed.

Interior monitor
The function of the passenger compartment monitoring sensor can be checked under the "Interior protection" menu item. When movement is detected in the passenger compartment, the alarm horn is activated briefly while the interior lighting and direction indicator lights go on continuously.

Tilt sensor (country version)
The external tilt sensor is active at the same time as the output for controlling external electronics. During this time, a change in the vehicle tilt triggers an alarm. The current tilt of the vehicle is stored as a reference value during a calibration phase defined for the tilt sensor. The system has an alarm siren with a rechargeable battery supply which can emit an alarm if the vehicle battery is removed.

Power-on behaviour
After the operating voltage is switched on, the system is set to the operating state which it was in before the supply voltage was switched off.

For this purpose, all necessary operating parameters are stored in a permanent memory. If the system was disconnected from the supply in the armed state, this is entered as a fault in the status memory. The same applies if the system is disconnected from the supply voltage during an alarm output. The alarm output is continued as soon as the necessary supply voltage is available.

Activation status memory
The alarm-triggering components that are in the non-active state during alarm system activation and that are therefore blocked for alarm triggering are stored in the activation status memory. The activation type is also saved. If the vehicle is secured, e.g. by remote control, and the oddments tray is open, this is indicated by the alarm system control memory via a brief horn signal. This status is stored in the activation status memory under "Oddments tray activation type: - by remote control-". This function can be used in troubleshooting, if a faulty micro switch or faulty wire happens to be the cause for the horn signal. Reading out the activation status memory can help to track down the faulty alarm-triggering component, e.g. front lid, rear lid, oddments tray, etc.

Play prevention
If the central locking system is actuated 11 times in less than 5 seconds, further operation is blocked for 30 seconds. If the last command before play prevention activation was a command to open the central locking system, then it is possible to give a further command which is independent from play prevention to close the system. For every further time that play prevention is activated the blocking time is doubled, up to a maximum of 240 seconds. The blocking time is cleared when a door is opened, and if play prevention is activated again, blocking time starts at 30 seconds.

System description
The following functions are integrated in the alarm system control module:
- Alarm system
- Immobiliser
- Radio receiver
- Central locking
- Comfort control
- Passenger component monitoring

Versions of the control module







Functions of the alarm system:
- Monitoring of outer panels of vehicle by contact switches.
- Attempted break-ins are detected and indicated by audible and visual signals.
- The alarm horn, alarm siren (country-specific regulations) and interior lights are activated for alarm output. The system can be enhanced by connecting additional sensors (glass breakage sensor, tilt sensor).

Functions of the central locking system:
Unlike previous systems, a two-motor lock is used here.
- Locked motor
- Safe motor

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 states:
- Action 1 - If the lock is actuated once, the so-called "Safe locking - door secured" function is activated. The doors can be opened only with the key, but not with the inner door handles.
- Action 2 - If the door lock is actuated twice within 1 second, the vehicle is not accessible from the outside, but can be unlocked using the inner door handles.
- Emergency locking. This locking state is activated by actuating the door lock three times and represents an emergency function. If the functional capability of the overall system is impaired because, for example, one door cannot be closed, it is still possible to activate the other security functions in this way. Point 1 is activated when the system is operated via the hand-held transmitter. The position of the doors is checked by limit switches in the lock.

The conditions for completing a locking process from unlocked to locked are listed in the following table.

System test
All components of the alarm system (except for terminal 15) can be checked for operation under the "System test" menu item. During the system test a bar runs across the screen, and if, for example, the oddments tray is opened, an alarm is triggered. This alarm output differs from the usual alarm output in that the alarm horn is activated only for a short time. The alarm output is accompanied by interior lighting and direction indicator lights.

NOTE: The function of the passenger compartment monitoring sensor can be checked under menu item "Interior protection". When movement is detected in the passenger compartment, the alarm horn is activated briefly while the interior lighting and direction indicator lights go on continuously.

Undervoltage
If the battery voltage falls below 8.5 V, an undervoltage occurs. If the battery voltage exceeds 9 V, the undervoltage is no longer present. If an undervoltage occurs, the inputs Door lock barrel open and Door lock barrel closed are evaluated as inactive irrespective of their state. It is not possible to activate the central locking system via the door lock barrel when an undervoltage occurs. The alarm system cannot be activated in the event of undervoltage.

Load disconnection
If the vehicle is locked up, some loads are disconnected from the supply voltage in order to conserve the battery. Load deactivation is activated if at least one of the following requirements is fulfilled:
- 10 minutes after locking up the vehicle via hand-held transmitter or door lock as well as after re-locking
- 2 hours after pin 86 S is switched off
- 2 hours after the central locking system is unlocked via door lock or hand-held transmitter
- 2 hours after alarm output

Load disconnection is deactivated if at least one of the following requirements is fulfilled:
- Pin 86 S is switched on
- Pin 15 is switched on
- A valid transponder is detected
- The vehicle is unlocked or locked via hand-held transmitter or door lock
- A door is opened
- Alarm output

Behaviour in the case of servicing
When removing the:
- vehicle battery
- alarm siren
- alarm control centre

an activated tilt sensor will trigger an alarm. In order to carry out servicing work, the alarm siren must be switched off before the work is commenced. To switch it off, insert the vehicle key with valid transponder into the ignition lock and rotate to activate the buzzer contact. Components can be removed without triggering the alarm as long as the vehicle key remains inserted.

Lid release locking
Electric locking is carried out by the alarm system control module and is valid for the following country codings:
- USA
- England
- Belgium

Functioning can be checked under "Tank locking" in the Drive links menu item. This locks not only the tank cap but also the front and rear lid release.
