Troubleshooting Procedure

Troubleshooting procedure
Troubleshooting can only be performed when the fault is present. In other words, specific troubleshooting can only be performed in accordance with instructions (given under Diagnosis/troubleshooting for each fault code) if the entry has the status present in the fault memory.

If the fault is currently not present, please check the following:
- Diagnostic conditions are met.
- All plug connections and ground points of the affected current path are OK.
- View the fault frequency counter in the Porsche System Tester II 9588 using the fault memory Info key F8 under Extended fault memory and try to reach conclusions about eliminating any loose contacts in the system.
