Catalytic monitor not ready?

Yes, the engine operating temperature is normal, for every cycle the tempurature reaches 219 or so. All monitors are being reset except the Cat. Last night I decided to erase and start all over again (this was done after running 20 warm up cycles). I know I could have waited longer but I decided to start fresh. There were no codes. As far as software updates, this model has been discontinued, and I suppose GM does not have any further updates.

That is similar to what I usually do: idle 5 minutes, idle with 1000 rpm steady for 1 minute, 5 minutes at 35 mph, 5 minutes at 45 mph, 3 minutes at 55 mph, decelerate to 20 mph without braking, back up to 60 mph for 5 minutes, back to city traffic and stop and go, then idle for 3 minutes and off. From cold repeated for 20 cycles. Today, did the same, tried to hook up the Innova lat + with live data scanner: it gave me error KW 2000 unable to communicate bus can. Previously there were similar codes (but not recently) those were see image below.

I did a total of two more warm-up drive cycles after re setting the DTC and the CAT cleared.

I forgot to mention although the CAT did clear, the HTR is not clearing now. The reset allowed me to clear the CAT but I'm sure why the HTR is not clearing. What are the specific HTR drive cycle components? What part of the drive cycle is essential for this step?

Well, Ken, it cleared as well and got it to pass. I did some more research, and I found out what part of the cycle clears the H.T.R. To all ow the E.C.M to calculate the data for the O2 heater sensor, the exhaust must not get too hot (something that is needed to monitor the Catalytic convertors (the opposite applies here). The engine needs to be cold (within 11 degrees F of ambient temperature). The idle must be about 2 to 3 minutes (no throttling should be done here. In other words, the RPM should remain steady). The car then can be driven gently for about 5 minutes at 25 to 45 mph (the lower the speed, the better). Shutting off the engine and removing the key (must not restart or turn the ignition on for at least 15 minutes after the gentle drive I mentioned). This will allow the E.C.M to calculate the data from the heater sensor. It is important not to turn on any heating or air conditioning, lights or radio in order to keep the load to a minimum (again this is not the case with other monitors). So, in summary, different monitors require different drive cycle procedures. That is why most people get frustrated when they follow the drive cycle procedure but don't clear everything. What cleared the Catalytic converter was getting the exhaust hot enough for the E.C.M to calculate the Data from both Catalysts. Thank you again.
