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