Sure. It keeps a record of problems it sees for 100 ignition cycles (every time you turn the key to the run position counts as an ignition cycle). Besides, after you do a KOEO test, do a KOER test. That way the ECM is specifically testing things while the engine is running. If you need help with this, let me know.
Take care
