YARIS (EM01V0U)

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 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.

[A]: System Title

[B]: 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

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

[D]: Indicates related system.

[E]: Indicates the code for the (male and female) connectors which are used to join two wire harnesses. The connector code consists of two alphabetical and one numerical characters.

Female

Male ( )

The first character of the connector code indicates the alphabetical code allocated to the wire harness which has the female connector, and the second shows that of the wire harness which has the male connector.

The third character indicates a serial number used to distinguish between the wire harness combinations in cases when more than one of the same combination of wire harnesses exist

(e.g. CH1 and CH2).

Symbol ( ) indicates the male terminal connector. Numbers outside connector codes indicate the pin numbers of both male and female connectors.

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

[G]: 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

YARIS (EM01V0U)

B HOW TO USE THIS MANUAL

[O]System Outline

Current 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 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 lamp 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.

B HOW TO USE THIS MANUAL

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 ( A1 , A2 and D4 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.

VOLTAGE CHECK

(a)Establish conditions in which voltage is present at the check point.

Example:

[A]– Ignition SW on

[B]– Ignition SW and SW 1 on

[C]– Ignition SW, SW 1 and Relay on (SW 2 off)

(b)Using a voltmeter, connect the negative lead to a good ground point or negative battery terminal, and the positive lead to the connector or component terminal.

This check can be done with a test light instead of a voltmeter.

CONTINUITY AND RESISTANCE CHECK

(a)Disconnect the battery terminal or wire so there is no voltage between the check points.

(b)Contact the two leads of an ohmmeter to each of the check points.

If the circuit has diodes, reverse the two leads and check again.

When contacting the negative lead to the diode positive side and the positive lead to the negative side, there should be continuity.

When contacting the two leads in reverse, there should be no continuity.

(c)Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting of the electrical circuit.

FINDING A SHORT CIRCUIT

(a)Remove the blown fuse and disconnect all loads of the fuse.

(b)Connect a test light in place of the fuse.

(c)Establish conditions in which the test light comes on. Example:

[A]– Ignition SW on

[B]– Ignition SW and SW 1 on

[C]– Ignition SW, SW 1 and Relay on (Connect the Relay) and SW 2 off (or Disconnect SW 2)

(d)Disconnect and reconnect the connectors while watching the test light.

The short lies between the connector where the test light stays lit and the connector where the light goes out.

(e)Find the exact location of the short by lightly shaking the problem wire along the body.

CAUTION:

(a)Do not open the cover or the case of the ECU unless absolutely necessary. (If the IC terminals are touched, the IC may be destroyed by static electricity.)

(b)When replacing the internal mechanism (ECU part) of the digital meter, be careful that no part of your body or clothing comes in contact with the terminals of leads from the IC, etc. of the replacement part (spare part).

DISCONNECTION OF MALE AND FEMALE

CONNECTORS

To pull apart the connectors, pull on the connector itself, not the wire harness.

HOW TO REPLACE TERMINAL

(with terminal retainer or secondary locking device)

1. PREPARE THE SPECIAL TOOL

HINT : To remove the terminal from the connector, please construct and use the special tool or like object shown on the left.

2.DISCONNECT CONNECTOR

3.DISENGAGE THE SECONDARY LOCKING DEVICE OR TERMINAL RETAINER.

(a)Locking device must be disengaged before the terminal locking clip can be released and the terminal removed from the connector.

(b)Use a special tool or the terminal pick to unlock the secondary locking device or terminal retainer.

NOTICE:

Do not remove the terminal retainer from connector body.

[A]For Non–Waterproof Type Connector

HINT : The needle insertion position varies according to the connector’s shape (number of terminals etc.), so check the position before inserting it.

”Case 1”

Raise the terminal retainer up to the temporary lock position.

”Case 2”

Open the secondary locking device.
