Removing And Installing Display And Operator Control Unit (Pcm): Notes

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

As of model year '01, the tolerance of the speed display has been restricted. This was achieved by changing the software ("K-number") on the instrument cluster and PCM control module. The "K-number" varies depending on vehicle type and country equipment.
The reason is as follows: different displays of the total mileage and the fuel consumption/average consumption in the instrument cluster and the PCM control module.
Therefore, in the case of repairs, the K-number in the PCM control module must be corrected with the Porsche System Tester 2 (PST2) after the installation of a new PCM control module or a new instrument cluster in vehicles as of model year '01. > If this correction is not carried out, conflicting values for the total mileage and fuel consumption/average consumption will be displayed on the instrument cluster and the PCM control module when in driving mode.
