When troubleshooting any problem, first understand the operation of the circuit where the problem was detected (see System Circuit section), the power source supplying power to that circuit (see Power Source section), and the ground points (see Ground Point section) When the circuit operation is understood, begin troubleshooting of the problem circuit to isolate the cause Use Relay Location and Electrical Wiring Routing sections to find each part, junction block and wiring harness connectors, wiring harness and wiring harness connectors and ground points of each system circuit Internal wiring for each junction block is also provided for better understanding of connection within a junction block Wiring related to each system is indicated in each system circuit by arrows (from , to ) When overall connections are required, see the Overall Electrical Wiring Diagram at the end of this manual *The information in this manual is about the wire harnesses Information about component and assembly parts is for reference, but in some cases this reference information might not be included or might differ from the actual vehicle When inspecting or repairing a vehicle, refer to the relevant Repair Manual Example: Front right door When inspecting or repairing, refer to the Repair Manual Wire harness Component parts Assembly parts CAMRY (EM20E0EV) B HOW TO USE THIS MANUAL * The
