Thank you for taking time to ask your Honda question on JustAnswer. My name is ***** ***** online handle is Honda-Man I will be assisting you. I have over 21 years experience repairing strictly Honda vehicles.

The catalytic converter needs to be warmed up before the monitor can run. A drive cycle needs to be done from a cold start. Overnight is best to make sure it's completely cooled down. The converter heats up when exhaust flows through it so highway driving is quickest. A level road without any stops is also best. At idle the converter won't get hot enough to allow the catalyst to function because of lack of exhaust flow. Hold at a steady speed of 55 to 60 mph for 5 minutes. Catalytic converter efficiency, EGR flow, ignition misfire, fuel trim, EVAP system and oxygen sensors operation will now be checked.

The cables might be a problem but not too likely. Might as well clan them up just to be sure. I would go to the check station and not shut it off until you are told to. The monitor will keep once passed until it's all the way cooled down.
