Having problems with your Cars & Trucks ?

2003 gmc jimmy. Engine light is on. Periodically the abs and park brake lights come on also. When abs is on , I lose all abs. Was told its one of two problems. Thermostat or ECM is gone. Is the ECM located on the passenger fender well in engine compartment? It says Delphi on it and is gray? If not where is it located. Thanks.
