Interruption in Power Supply
An interruption in the power supply does not require renewed “normalization”. If the
power supply is interrupted during initialization the entire procedure is invalid and the sys-
tem must be re-initialized.
Deleting the Initialization
The initialization is deleted under the following circumstances:
• Failure of the supply voltage during initialization
• Hall sensor fault detected
• Position implausible
• Certain instructions in the diagnosis
• Modified/changed vehicle coding
• Coding data faulty
