Possible TIPM failure

I replaced the transfer case and front driveshaft. Original transfer case blew up. I have no 4wd. I have no input to the actuator at the yellow and green wires when I select 4WD or 2WD. I have no output from the TIPM C4 connection T101 and T102 (green and yellow) I have one code for the oxygen sensor. I also have 12V at the actuator A918 and 5V reference at the actuator T103. Should I replace the TIPM?
