Dummy Lights on

I’ve got an 07 Prius with the abs, vsc, ! and parking brake light on. I replaced both front struts and a control arm. Only thing I can think might’ve done it is I disconnected the abs sensor and turned the car on. I unhooked the battery overnight and the dummy lights were still on the next morning. I also cleaned metal filings off the abs sensor magnet. It also doesn’t seem like abs is working, it seems like the wheels lock up when braking. I also replaced a front caliper.
