Test condition:
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.
During basic setting, the AC compressor is switched off and the carbon canister valve is closed.
Procedure:
Choose the lambda adaption function.
Read off the value columns. Required results: additive lambda adaption (cylinder bank1 and 2) –4 % to 4 % and multiplicative lambda adaption (cylinder bank1 and 2) –4 % to 4 %.
On completion of basic setting, the carbon canister valve is activated automatically.
