The engine has started and lambda control is active.
A multiplicative adaptation has been done.

OK report:

Provided that the fault criteria are not fulfilled during the operating cycle, there is an OK report upon ignition shut-off before the engine stops. Two types of OK reports are possible: Type 1: If there is already a DTC stored for the diagnosis and operating conditions were the same (coolant temperature over or under 71°C, engine speed 375 rpm and load 10%). Type 2: If there is no DTC stored for the diagnosis or if operating conditions were not the same.

(See section Fault handling II, "Emission-related misfiring or fault in fuel system" for more information.)
