Read off the value columns. Prescribed value injection time 1,5-3,0 ms; additive lambda adaption –12 % to 12 %; multiplicative lambda adaption –12 % to 12 %; status of tank venting -adaption (instantaneous lambda adaption), TE not active (conditions for lambda adaption not met).
On completion of basic setting, the carbon canister valve is activated automatically.
