2004 COROLLA (EWD533U)3

HOW TO USE THIS MANUAL B

This 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, splice points, and ground points of eachsystem circuit. Internal wiring for each junction block is also provided for betterunderstanding 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 ElectricalWiring Diagram at the end of this manual.

B HOW TO USE THIS MANUAL* The system shown here is an EXAMPLE ONLY. It is different to the actual

circuit shown in the SYSTEM CIRCUITS SECTION.


B[A] : System Title[B] : Indicates a Relay Block. No shading is used and

only the Relay Block No. is shown to distinguish itfrom the J/BExample: Indicates Relay Block No.1

[C] : ( ) is used to indicate different wiring andconnector, etc. when the vehicle model, enginetype, or specification is different.

[D] : Indicates related system.[E] : Indicates the wiring harness and wiring harness

connector. The wiring harness with male terminal isshown with arrows ( ).Outside numerals are pin numbers.

Female Male ( )The first letter of the code for each wiring harnessand wiring harness connector(s) indicates thecomponents location, e.g, E for the EngineCompartment, I for the Instrument Panel andSurrounding area, and B for the Body andSurrounding area.When more than one code has the first and secondletters in common, followed by numbers (e.g, IH1,IH2), this indicates the same type of wiring harnessand wiring harness connector.

[F] : Represents a part (all parts are shown in sky blue).The code is the same as the code used in partsposition.

[G] : Junction Block (The number in the circle is the J/BNo. and the connector code is shown beside it).Junction Blocks are shaded to clearly separatethem from other parts.

3C indicates thatit is insideJunction BlockNo.3

B HOW TO USE THIS MANUAL

Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light 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 light 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.

B HOW TO USE THIS MANUALThe ground points circuit diagram shows the connections from all major parts to the respective ground points. Whentroubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identifythe problem ground quickly. The relationship between ground points ( EA , IB and IC shown below) can also bechecked this way.

BThe Current Flow Chart section, describes which parts each power source (fuses, fusible links, and circuit breakers)transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each systemare explained. Since all System Circuit diagrams start from the power source, the power source system must be fullyunderstood.

Indicates a connector which is connected to a short terminal.Junction Connector

Short TerminalSame Color

Junction connector in this manual include a short terminal which isconnected to a number of wire harnesses. Always performinspection with the short terminal installed. (When installing thewire harnesses, the harnesses can be connected to any positionwithin the short terminal grouping. Accordingly, in other vehicles,the same position in the short terminal may be connected to a wireharness from a different part.)Wire harness sharing the same short terminal grouping have thesame color.

[C] : Parts CodeThe first letter of the code is taken from the first letter of part, and the numbers indicates its order in parts whichstart with the same letter.
