ECU Cycle
I am very confuse. I need some help passing my smog inspection.
They said my ECU cycle is not complete yet. Something like that. They said run it on the freeway for 1 hour straight above 60 mph. They said stop n go wont help.
They said the owner I bought the car from erase all the CELs before I bought it.
My car is a 1998 Honda Lude.
Help please

If the ECU has been out of the car for a while, it won't communicate with the emissions software. Lots of times it will say "OBD not ready." All you need to do is drive the car around for a while.

It's called a readiness moniter. Your car hasn't completed the moniters yet so it fails the emissions test. Driving it for an hour over 60mph isn't ness.
You must complete one or two of drive cycles and also meet the standards the ecu wants to see before it will run the moniter. For example the ecu watchs all the inputs and sees the engine coolant temp. goes to 180. Then it waits to see that the car goes into closed loop, then it etc..etc.. once it sees what it needs the car runs a test of whatever it's testing, egr, cat. convertor, etc.. and it either completes or it doesn't. You need all to complete except two I believe at this present time....It's suppose to change though. OBD2 and up we are talking about here....
