Test condition:
Engine idling.
No faults stored.
Engine temperature above 85 °C.
No leaks in the exhaust system.
All electrical loads switched off.
Note:
Used to check the lambda adaption procedure.
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. Prescribed value injection time 1.7-5.0 ms; additive lambda adaption –10 % to 10 %; multiplicative lambda adaption –8 % to 8 %; status of tank venting –adaption (instantaneous lambda adaption). TE not active (condition for lambda adaption not met).
On completion of basic setting, the carbon canister valve is activated automatically.
