General instructions / safety instructions

The following points must be observed during vehicle diagnosis:

After the battery is connected, volatile memories must be reprogrammed. In the case of radio coding and tuning, the customer must be informed of decoding and the deleted tuner memory.
The coding, calibration and headlight adjustment must be observed after an HBA control module or an angle sensor for HBA has been replaced or the running gear has been modified.
After troubleshooting or repairs, erase the fault memory with the Porsche System Tester 2 and carry out a test drive.
After the test drive, read out the fault memory with Porsche System Tester 2 again.

> Never disconnect battery with engine running.
> Never start engine without securely connected battery.
