  • Page 2 INTRODUCTION This manual consists of the following 12 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 3 HOW TO USE THIS MANUAL This manual provides information on the electrical circuits installed on vehicles by dividing them into each system circuit. 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...

  • Page 7 : Explains the system outline. : Indicates values or explains the function for reference during troubleshooting. : Indicates the reference page showing the position on the vehicle of the parts in the system circuit. Example: Part A (Power Window Master SW) represents code P4 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 that letter.
  • Page 8 HOW TO USE THIS MANUAL The Power – Load 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 9 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 ( , and shown below) can also be checked this way.
