The Toyota FJ Cruiser (FJC) is a retro-style compact SUV produced by Toyota introduced as a concept at the 2003 and went on sale in early 2006 as a 2007 model.
The following wiring diagram and electrical system troubleshooting apply for FJ Cruiser 2007. This manual provides information on the electrical circuits installed on vehicles by dividing them into a circuit for each system. 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). See the 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 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.
