Preconditions for the test:
Engine idling.
No faults stored.
Engine temperature above 80 °C.
No leaks in the exhaust system.
All electrical loads switched off.
Note:
Used to see the lambda adaption value for the sond before the catalytic converter.
During basic setting, the AC compressor is switched off and the carbon canister valve is closed.
Procedure:
Choose the lambda adaption, before catalytic converter function.
Read off the value columns. Required results: additive lambda adaption (bank1, sond1) –6 % to 6 % and multiplicative lambda adaption (bank1, sond1) –10 % to 10 %.
On completion of basic setting, the carbon canister valve is activated automatically.
