Objectives 652 Body Electrical Diagnosis 2. Given access to the EWD, the technician will be able to demonstrate his knowledge of what’s available in the EWD by locating the following sections and features (paper version and on TIS EWD Viewer): • Locate assigned System Circuit Diagrams in the EWD • Identify each of the symbols used on the system diagram, wire color, wire identification, and pin number location • Locate, How to use the Manual; Abbreviations; Glossary of Terms & Symbols:
Relay Locations & JB Inner Circuit Diagram; Relay Blocks; Connector List; Part Numbers of Connectors; Overall Electrical Wiring Diagram; and support sections, System Outline & Service Hints • Locate components, ground points, connectors, junction blocks, harness to harness connectors; switches; relays; splice points; in the manual and on the vehicle • Power source section and ground point section and describe how each is used when diagnosing a problem 3. Given a 2010 Camry Remote Control Mirror and a Radiator & Condenser Fan System Circuit Diagram the technician will be able to:
• Apply basic current flow theory to the diagram by tracing the path of current flow through the circuit from B+ to ground • Configure the switches/relays in the circuit to the appropriate positions for the operating conditions described • Identify the symbols used on the system circuit diagram • Predict voltage, amperage, and resistance values at various locations on the diagram under a variety of conditions (normal and abnormal operation) 4. Given a DVOM with an inductive clamp and a simple System Circuit Diagram, the technician will be able to demonstrate how to:
• Make resistance, current measurements • Measure open circuit voltage, available voltage and voltage drop • Properly identify a parasitic load in a circuit d Technical Training
