After jumpstarting my 2009 Chevy HHR 2.2l the engine light, traction control light came on, the speedometer and odometer stopped working and the info didplay say service ESC traction and power steering. The shifts poorly if at all and some of the lights do not function.. I took it to Autozone and got a P1682 code a u0101 code. Everthingpoints to the Ecm. Would replacing it do anything or is it something else.. I can get a used ECM for under$100
