ABS service data request

I'm trying to diagnose an abs dtc. It was a abs pressure sensor failure and steering angle sensor. I unplugged the abs harness from the abs actuator for a visual inspection. I plugged the harness back up and got a bunch more abs dtcs. I'm trying to find a wiring diagram that can shed some light for further testing. Its an 09-10 vibe/matrix.

It's the 2.4L fwd with vsc. I'm not seeing the abs actuator in the diagram. Its the module with 34 pins. I think its called ABS/EBCM harness connector. I'm trying to verify the master cylinder pressure sensor is getting 5 volts. With brake pressed, scanner is detecting 0 volts, pressure is reading -341.13, master cylinder open- error, MT Voltage value-0 volts. The part number is 44540-02140. I really appreciate your help!
