His ECM could not communicate because of low reference voltage. The PCM (Powertrain controller manages engine and transmission) uses basic data like vehicle speed to perform timely fueling or gear change decisions. Some people in warmer climes leave it disconnected. Because thrills like these dont happen often. First, hook up the DVOM (positive lead) to Pin #7 into the back of the DLC connector, the ground lead attached to the chassis. CAN networks, as you know, connect all the controllers together using a twisted pair of wires known as the CAN lines.
