How To Use This Service Information: Notes

This information provides information on the electrical circuits installed on vehicles by dividing them into a circuit for each system.

The actual wiring of each system circuit is shown from the point where the power source is received from the battery as far as each ground point. (All circuit diagrams are shown with the switches in the OFF position.)

When troubleshooting any problem, first understand the operation of the circuit where the problem was detected (see OEM SYSTEM CIRCUITS -- HYBRID , the power source supplying power to that circuit (see OEM POWER SOURCE (CURRENT FLOW CHART) (HYBRID) , and the ground points (see OEM GROUND POINTS -- HYBRID ). See the [O] System Outline to understand the circuit operation.

When the circuit operation is understood, begin troubleshooting of the problem circuit to isolate the cause. Use Relay Location (see OEM RELAY LOCATONS -- HYBRID ) and Electrical Wiring Routing (see OEM ELECTRICAL WIRING ROUTING (HYBRID) ) 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, refer to the OEM OVERALL ELECTRICAL WIRING DIAGRAM (HYBRID) article.

NOTE: *The information provided here 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 service information .
