Headlamp: Service Precautions




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 a 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.


Caution!
Danger of damage due to improper handling of the battery and the control module connectors!
- Never disconnect battery with engine running.
- Never start engine without securely connected battery.
- Never pull off or push on plug connections of the control modules or other electronic components when the ignition is switched on.
