Handbook 652 Body Electrical Diagnosis EWD Overview Because the EWD contains so much information, it takes a little time to learn where the information is located and what the diagrams and symbols can tell you. We will take a detailed look at all of these features, and how to use them in diagnosing an electrical problem. The Index The first page of the printed EWD is an index to all the sections of the manual. With the large number of pages and sections in the EWD, the fastest way to find the diagram or information you need is to use the index. The example illustrated here is the index for the 2010 Camry.
It is representative of all the EWDs from 1990 to present with the following exceptions: • The Part Number of Connectors section was not introduced until the 1999 model year . Prior to that year, connector part numbers are not included in the EWD. • The Connector List section was not introduced until the 2000 model year . For earlier years, connectors are listed with the system circuits to which they belong. Technical Training 51
