ZPC or ABS issue?

Ok so stupid question but I am not really seeing a separation of these two in posts. After a lift I have a slip indicator and MTS light but NO ABS light on. I am seeing where people are saying it can still be ABS even if I have no ABS light on? Or am I looking at a ZPC which I plan to do after my alignment.

This is a 2016 TEP w/KDSS.
 
I'm not sure I understand what you're saying?

Do you mean that after you lifted the vehicle those lights came on or after you tried to do a ZPC?

ABS DTCs are a little weird in that there are failures that will immediately set a DTC and turn on the warning lamp (circuit open/shorted, pump failure, etc.), other failures may not set until the vehicle has been driven anywhere from 10ft or more (Zero Point Calibration issues, wheel speed sensor abnormal operation, etc.) The reason for that is because for some of those DTCs they way they are detected is by comparing how the sensors read when the vehicle is in motion vs. what it's expecting to see.

I also do believe that with the MTS system you need to follow the steps and make sure you actuate all the features towards the end of the ZPC process, otherwise it sets DTCs because it doesn't see those systems as functional (ran into that a couple times).

Also I'd just do a ZPC after the alignment for the best results in my opinion.
 
Sorry, I did not mean to be confusing. What I meant was after lifting those lights are on but I have no ABS lights. I do plan to perform the ZPC once my new tires are on and alignment is completed (tomorrow) however in many of the posts related to this type of issue I am seeing that ABS is often suspect even without the ABS light being on so I was curious if that is true.
