Coding New PCM Control Module
Vehicle Type:
911 Turbo (996)
Model Year:
As of 01 (1)
Concern:
Proper coding of the instrument cluster after a new PCM is installed
Information:
As of model year 2001 (1), the software ("K-number"), which calculates total mileage and fuel consumption in the PCM, has been changed. The software ("K-number") has also been changed in the instrument cluster to coincide with the PCM.
If a new PCM is installed in a model year 01 and later vehicle, the instrument cluster will have to be re programmed using the Porsche System Tester (PST2). Failure to do so will result in the instrument cluster displaying a different total mileage and fuel consumption than the PCM.
Note:
PST2 software version 13.0 or higher is required to reprogram the instrument cluster.
Parts:
