Electrical-cluster-dtc plug-ecm-pcm
I have a 2005 Suburban 5.3L (z) that has an electrical problem. The vehicle starts but cluster lights and guages go nuts, come on go off as well as the radio. I have an advanced Actron scan tool that gets power through the DTC plug but wont communicate, link over, communication error. Has anyone had this problem or can help?
