HOW TO USE THIS MANUAL BThis manual provides information on the electrical circuits installed on vehicles bydividing them into a circuit for each system.The actual wiring of each system circuit is shown from the point where the powersource is received from the battery as far as each ground point. (All circuitdiagrams are shown with the switches in the OFF position.)When troubleshooting any problem, first understand the operation of the circuitwhere the problem was detected (see System Circuit section), the power sourcesupplying power to that circuit (see Power Source section), and the ground points(see Ground Point section). See the System Outline to understand the circuitoperation.When the circuit operation is understood, begin troubleshooting of the problemcircuit to isolate the cause. Use Relay Location and Electrical Wiring Routingsections to find each part, junction block and wiring harness connectors, wiringharness and wiring harness connectors and ground points of each system circuit.Internal wiring for each junction block is also provided for better understanding ofconnection 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 ElectricalWiring Diagram at the end of this manual.3YARIS (EM01V0U)

B HOW TO USE THIS MANUAL[O]System OutlineCurrent is applied at all times through the STOP fuse to TERMINAL 2 of the stop lamp SW.When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flowsthrough the rear lights warning light to TERMINAL 4 of the light failure sensor.Stop Light Disconnection WarningWhen the ignition SW is turned on and the brake pedal is pressed (Stop lamp SW on), if the stop light circuit is open, the currentflowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects thedisconnection and the warning circuit of the light failure sensor is activated.As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lightswarning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warningcircuit on and holds the warning light on until the ignition SW is turned off.[P]: Parts LocationCodeSee PageCodeSee PageCodeSee PageH436H736H1738H636H938J738[Q]: Relay BlocksCode1[R]See Page18Relay Blocks (Relay Block Location)R/B No.1 (Instrument Panel Brace LH): Junction Block and Wire Harness ConnectorCodeSee PageJunction Block and Wire Harness (Connector Location)3C22Instrument Panel Wire and J/B No.3 (Instrument Panel Brace LH)IB20Instrument Panel Wire and Instrument Panel J/B (Lower Finish Panel)[S]: Connector Joining Wire Harness and Wire HarnessCodeSee PageJoining Wire Harness and Wire Harness (Connector Location)CH142Engine Room Main Wire and Instrument Panel Wire (Left Kick Panel)HJ150Instrument Panel Wire and Floor Wire (Right Kick Panel)[T]: Ground PointsCodeSee PageGround Points LocationH150Under the Left Center PillarH250Back Panel Center6YARIS (EM01V0U)
