2007 Hummer H3 3.7L in limp mode with multiple OBD codes. Help please

I recently bought a 2007 Hummer H3 2007 3.7L. The previous owner couldn't fix the issue; the vehicle is in limp mode and I can't turn off the headlights even with the keys out and car locked. Also unable to engage any of the 4wd modes and shows a service 4wd/traction control error on the dash. Please find attached pics of the OBD codes found on scanning. Would it be the ECM? Please help me in fixing this.
