2004 Corolla Wiring Manual-All

HOW TO USE THIS MANUAL B This manual 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 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, splice points, 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.

[N]
System Outline 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 flows through the rear lights warning light to TERMINAL 4 of the light failure sensor. Stop Light Disconnection Warning When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the current flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects the disconnection 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 lights warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warning circuit on and holds the warning light on until the ignition SW is turned off.

The ground points circuit diagram shows the connections from all major parts to the respective ground points. When troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify the problem ground quickly. The relationship between ground points ( EA , IB and IC shown below) can also be checked this way.

The ”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 system are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully understood.

Junction Connector

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

[A] : System Title [B] : Indicates the wiring color. Wire colors are indicated by an alphabetical code. B L P = Black = Blue = Pink W = White V Y = Violet = Yellow G = Green BR = Brown SB = Sky Blue LG = Light Green GR = Gray

[F] : Junction Block (The number in the circle is the J/B No. and the connector code is shown beside it). Junction Blocks are shaded to clearly separate them from other parts. Example:
3C indicates that it is inside Junction Block No.3

R = Red O = Orange

The first letter indicates the basic wire color and the second letter indicates the color of the stripe.
Example: L–Y

[G] : Indicates related system. [H] : Indicates the wiring harness and wiring harness connector. The wiring harness with male terminal is shown with arrows ( ). Outside numerals are pin numbers.

L (Blue)

Y (Yellow)

2004 COROLLA (EWD533U)

[C] : The position of the parts is the same as shown in the wiring diagram and wire routing. [D] : Indicates the pin number of the connector. The numbering system is different for female and male connectors.
Example : Numbered in order from upper left to lower right Numbered in order from upper right to lower left Female Male ( )

[I]

: ( ) is used to indicate different wiring and connector, etc. when the vehicle model, engine type, or specification is different.

[J] : Indicates a shielded cable.
Female Male

The numbering system for the overall wiring diagram is the same as above [E] : Indicates a Relay Block. No shading is used and only the Relay Block No. is shown to distinguish it from the J/B.
Example : Indicates Relay Block No.1

[K] : Indicates and located on ground point. [L] : The same code occuring on the next page indicates that the wire harness is continuous.
