Notes on HHT diagnosis ATA - AD80.50-P-2000-06GH

Diagnosis of the anti-theft alarm (ATA) with the HHT  is only possible under certain conditions:

• The vehicle must have been unlocked correctly with the transmitter key before accessing the HHT diagnosis.
• Accessing the ATA diagnosis with the HHT must be carried out in the disarmed condition.

  Only when these two conditions are met is it possible to arm the ATA during HHT diagnosis (e.g. with the transmitter key).
