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 9588 Porsche System Tester II using the fault memory Info key [F8] under 'Extended fault memory' and try to reach conclusions about eliminating any loose contacts in the system.
