Hello I just Got my coilovers installed and got back my car and out of no where my tpms, steering and the tcs light blinks then stays on anyone can shine in on this it turned off randomly and sometimes I feel the hill start assist turns on when I am on flat ground

 

Sound like maybe the wheel speed or abs sensors got damaged or incorrectly reinstalled.

 

Thank you for the reply where would he wheel speed sensor be and would it be the same as the abs sensor??
