This manual provides information on the electrical circuits installed on vehicles away dividing them into a electric circuit for to each one system of rules.

The actual wiring of for each one system of rules lap is shown from the spot where the great power source is received from the battery as far as for each one ground point. (All tour diagrams are shown with the switches in the OFF position.)

When troubleshooting whatsoever problem, commencement understand the operation of the electric circuit where the trouble was perceived (visualise System Lap section), the index source supply power to it electric circuit (see World power Source section), and the ground points (find Ground Point section). See the System Outline to understand the circuit operation.

When the circuit operation is understood, begin troubleshooting of the problem electrical circuit to isolate the do. 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 conjugation blockage is also provided for punter understanding of connexion within a colligation block.

Wiring related to for each one 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.

System Outline

Current is applied in the least 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 commingle to TERMINAL 8 of the light failure sensor, and also flows through the rear lights warning light to Final 4 of the light failure sensor.

Cease Light Disconnection Dissuasive

When the ignition SW is soured on and the brake pedal point is pressed (Stop lamp SW on), if the stoppag lighting circuit is open, the current flowing from Depot 7 of the sick bankruptcy sensor to TERMINALS 1, 2 changes, so the light failure sensor detects the disconnection and the admonitory circuit of the light failure detector is activated.

As a consequence, the current flows from Pole 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 electrical circuit on and holds the red light on until the ignition SW is turned off.
