Abstract
A diagnostic method and system in a truck monitors voltages reported by electrical control units in a truck via a shared communication path called the data link. When a data logging unit on the data link detects an event, it persistently stores monitored data measured during a period that may span before and after the event occurred. The voltages measured and reported by electrical control units during this period are used to diagnose electrical wiring problems or other electrical problems in the electrical control units.
