Help needed! Driving cycle to pass smog

[Waldog213]

Help my car needs to pass smog. 4 'monitors are not ready and i have been driving alot. Im not sure what are thr driving cycle criteria to get them ready. Also there is a pending code in the memory about ecm power

Highway, around town, steady rate on flat at 55mph for 3 min, uphill, idle for a couple minutes downhill, use half a tank and refill... stuff like that all done after initial warm up.

In CA, you can have I think one incomplete (maybe two?), but the others should be done. No codes and a working CEL of course. Most all of the OBD2 drive pattern routines are similar, due to them all being OBD2. I think there might be a slight difference between manual and automatics.

So, I found a bunch of them online and you can use pretty much any of those on your car. I used google images with these terms "nissan system readiness test drive pattern". I hope that helps.

What ECM power code do you get? Is it possible that your monitors are resetting each time you turn off the ignition? Obviously that would be an issue to fix first.
