Default Smog and check engine

This might be a little long and I’ll have to get more information later, but I wanted to start by saying in California a check engine light immediately fails your smog test so I didn’t do it yet. I know that my ABS and traction control unit lights are on when I reset them while driving I do get the brakes to feel like they rumble a little bit, but I’m sure that probably doesn’t mean that the unit isn’t bad. I reset my codes for the traction control and the check engine light is off. I’m assuming that after around 100 miles of driving, it’ll come back on? Is there any way to get around it by pulling a fuse or something to the ABS and does anybody know exactly what fuse that is?
OK, I’ve updated the codes that I’ve had and I’ve cleared them before but the historical codes come back. Do I have to get one of those scanners to actually permanently delete the historical codes? Oh and one last thing I absolutely have a bad parasitic draw, which I’m assuming is possibly that ABS pump but anyway my battery was dead. Can that cause a check engine light as well? I’ve cleared codes and now I need to drive 100 or so miles to see if it comes back on the traction control and ABS lights always come on.

Bo333 h c
C1243 c
c1288 h c. This one popped up and the checked engine light came back on. I think this maybe the problem. Anyone know what this costs to fix?

Here in the Phoenix area they plug into the OBD port under dash and see if the systems are in ready or not ready.

Edit, a check engine light on will fail you here also.

I’ve failed, and been told to drive more to get into ready because I put in a new battery.

You can see on scanner, even a cheap Walmart $25.00 hyper tough scanner shows if all the emissions segments are in ready or not.

Does the ABS EBCM malfunction cause check engine light to come on, or ABS light to come on?

If just abs light is on they wouldn’t use that as a reason to fail you, would they?

I'm not 100% sure, but I don't think ABS light is tested as it's not part of the emissions control system.

I’m pretty sure that that is why my check engine light is on due to the traction control in the ABS when I go into my codes it’s a PCM code and when I clear it, the Check light obviously goes away. I’m assuming after 100 miles or so it comes back on. I haven’t done it in a while. It’s off right now, but the guy at the Wong station says your computer may not show that it’s ready yet to be tested, and it would fail them as well.

This. It feels like you want us to help but aren't giving us the means to do so.

Also, you can buy a cheap OBD2 dongle and download the appropriate app to check readiness as others pointed out. Last year I bought this cheap one to use with the Torque app on Android:

I checked - ABS codes are not part of the smog readiness check. If your state has a brake and light check they may make you fail that.

I suggest you pull the codes using the on board scanner - DO NOT clear them (for now)
