Events










NOTE:
- The occurrence of particular system errors is stored in the event memory. Furthermore, it is possible to read out the time of the occurrence by means of the F8 key. The time is shown in minutes. The events stored in the event memory concern components of the instrument cluster and also components of other control modules like PSM or DME. The system errors are stored in the event memory.
- During diagnosis, the events ABS failure and PSM failure are entered into the event memory via communication with the Porsche System Tester II No. 9588 and the respective warning lights are activated during the automatic control module search. In this case, no fault is present and the event memory is to be erased after completion of the diagnosis.

- Select menu item "New oil level characteristics" and change the coding with F8. After coding has been successfully completed, "New oil level characteristics" is displayed in the Porsche System Tester II No. 9588.
- Function successfully completed

NOTE:
- Synchronise K-number
- As of model year '02, the tolerance of the speed display has been restricted. This was achieved by changing the software "K-number" in the instrument cluster and PCM control module. The "K-number" varies depending on vehicle type and country equipment.
- Refer to the Technical Information.
- old/new oil level characteristics
- In order to eliminate the "blue smoke" problem, it is necessary to reduce the engine oil quantity by approx. 0.5 litre and to replace the oil dipstick with a modified version for vehicles up to model year '02 that were manufactured prior to 8 January 2002.
- Refer to Technical Information.

Total Mileage
It is possible to code the total mileage under this menu item after replacing the instrument cluster.
1. Connect the Porsche System Tester II No. 9588 and switch on the ignition
2. Select vehicle type 911 (996) and instrument cluster control module and press the key >>
3. Select the menu item "Total mileage" and press the key >>.
4. You are requested to enter the "Vehicle Ident. No.".
5. Enter Vehicle Ident. No. or accept with the key >>, check the entry and press key F7.
6. Observe the instructions of the Porsche System Tester II No. 9588, enter the total mileage with the tabulator keys, check and then press the F8 key to code the entered total mileage.

The total mileage can also be read out from the old instrument cluster under the menu item "Control module replacement" and can be transferred into the new instrument cluster if the old instrument cluster is still functional and if it is possible to establish communication with the Porsche System Tester II No. 9588.

Tank calibration
Refer "Calibrating fuel level sensor system".

Speedometer A
A speed can be simulated under this menu item to check the function of dynamic volume control (speed-dependent volume). If the function of the dynamic volume is switched on and the speed is simulated by means of the Porsche System Tester II No. 9588, the volume must change according to the speed. The higher the simulated speed, the higher the volume.

Control Module Replacement
Certain values can be read out of the old instrument cluster and can be transferred into the new instrument cluster. A prerequisite for this is that communication can be established between the old instrument cluster and the Porsche System Tester II No. 9588. The following values can be read out of the old instrument cluster and can be transferred into the new instrument cluster:
- Total mileage
- Tank calibration
- Vehicle Ident. No.

NOTE:
- The country coding is not read out and transferred via this function.
- Correct country coding is a prerequisite of the correct functioning of the instrument cluster.
