- If the fault memory is cleared, the ignition must be switched off, the ignition key removed and the ignition switched on again in order to check the fault path. Only in this way is another self-test carried out.
- When the coding is changed in the menu item "Change coding", the ignition must always be switched off afterwards and the key removed.
