Note on display zone 3:
A display only occurs when the diagnostic result occurred not due to a deviation of the oxygen sensor control (e.g. oxygen sensor 1 from EVAP canister) but due to a deviation of the idling controller within a certain tolerance range. Otherwise display zone 3 remains empty .
If specification "FTBV OK" is attained:
- Press C key.
