Instrument Cluster Diagnosis - System K22, K23, K27

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.
