Written for Toyota dealership mechanics, this factory-published original wiring diagram shows you how to follow the wiring for mid-year 2003 Camry models. Mid-year models are different from earlier 03 models in the following ways: VVTi (Variable Valve Timing-intelligent), new U151E automatic transaxle, new engine mounts, and new engine immobilizer system. For the 4 cylinder, the book covers improvements to the exhaust system for California specification cars. It will help you understand connector configurations, and locate and identify circuits, relays, and grounds. You will not find these wiring diagrams in the factory shop manual. Some wiring diagrams are black and white, but they frequently have color codes printed on each line of the diagram that represents a wire, and other diagrams in this book are in color. Although this manual is titled as a supplement, it is a complete wiring diagram for mid-year models. Covers 2003 Camry mid-year models including LE, SE sport, and XLE; the mid-year models include all 6 cylinder cars, and California specification 4 cylinder cars made after the middle of the model year.
