NOTE:
- When the coding is changed in the menu item "Change coding", the ignition must always be switched off afterwards and the key removed.
- After the ignition is switched on again, the new coding from the airbag triggering unit is updated and the stored faults can be erased.
- If the coding does not agree with the vehicle equipment, faults will be displayed that do not really exist.
