Preconditions for the test:
Engine idling.
No faults stored.
Engine temperature above 85 °C.
No leaks in the exhaust system.
All electrical loads switched off.
Gear selector set to P/N.
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 function: Lambda adaption.
Read off additive lambda adaption (bank 1, probe 1). Prescribed value –6 % to 6 %.
Read off multiplicative lambda adaption (bank 1, probe 1). Prescribed value –10 % to 10 %.
On completion of basic setting, the AC compressor and carbon canister valve are activated automatically.
