Page 1 A INTRODUCTION This manual consists of the following 11 sections: Section Description INDEX Index of the contents of this manual. INTRODUCTION Brief explanation of each section. HOW TO USE Instructions on how to use this manual. THIS MANUAL TROUBLE- Describes the basic inspection procedures for electrical circuits. SHOOTING ABBREVIATIONS Defines the abbreviations used in this manual.
Page 2 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.
Page 3 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.
Page 4 A : System Title J : Indicates the wiring color. Wire colors are indicated by an alphabetical code. B : Indicates a Relay Block. No shading is used and only the Relay Block No. is shown to distinguish it from the J/B. = Black = Black R = Red...

Page 6 Q : Explains the system outline. R : Indicates values or explain the function for reference during troubleshooting. S : Indicates the reference page showing the position on the vehicle of the parts in the system circuit. Example: Part “P 4” (Power Window Master SW) is on page 21 of the manual. * The letter in the code is from the first letter of the part, and the number indicates its order in parts starting with the letter.
Page 7 B HOW TO USE THIS MANUAL 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.
Page 8 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 ( shown below) can also be checked this way.
Page 9: C Troubleshooting
C TROUBLESHOOTING VOLTAGE CHECK (a) Establish conditions in which voltage is present at the check point. Example: - Ignition SW on - Ignition SW and SW 1 on - Ignition SW, SW 1 and Relay on (SW2 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.
Page 10 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. 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)
Page 11 C TROUBLESHOOTING 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.
Page 12 For Waterproof Type Connector HINT: Terminal retainer color is different according to connector body. Example: Terminal Retainer :Connector Body Black or White :Gray Black or White :Dark Gray Gray or White :Black “Case 1” Type where terminal retainer is pulled up to the temporary lock position (Pull Type).
Page 13 C TROUBLESHOOTING Push the terminal retainer down to the temporary lock position. c) Release the locking lug from terminal and pull the terminal out from rear. INSTALL TERMINAL TO CONNECTOR (a) Insert the terminal. HINT: 1. Make sure the terminal is positioned correctly. 2.
Page 14 C TROUBLESHOOTING DISCONNECTION AND CONNECTION OF BOLT TYPE CONNECTORS For engine control module in this vehicle, connections are used which require a bolt built into the connector to be screwed down to securely connect the connector. Disconnect the connector After completely loosening the bolt, the two parts of the connector can be separated.

Page 189 NOTICE: When inspecting or repairing the SRS, perform the operation in accordance with the following precautionary instructions and the procedure and precautions in the Repair Manual for the applicable model year. Malfunction symptoms of the supplemental restraint system are difficult to confirm, so the diagnostic trouble codes become the most important source of information when troubleshooting.
Page 190 The SRS has connectors which possess the functions described below: 1. SRS ACTIVATION PREVENTION MECHANISM Each connector contains a short spring plate. When the connector is disconnected, the short spring plate automatically connects the power source and grounding terminals of the squib to preclude a potential difference between the terminals.
Page 191 3. CONNECTOR TWIN-LOCK MECHANISM With this mechanism connectors (male and female connectors) are locked by two locking devices to increase connection reliability. If the primary lock is incomplete, ribs interfere and prevent the secondary lock.
