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 Ci

B HOW TO USE 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

[P] : Indicates the reference page showing the position on the vehicle of the parts in the system circuit. Example : Part ”L4” (Light Failure Sensor) is on page 36 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.

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 EA IB IC the problem ground quickly. The relationship between ground points ( , and shown below) can also be checked this way.

B 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.
