This manual of arms provides information on the electric circuits installed along vehicles by dividing them into a circuit for apiece system.

The actual wiring of each system tour is shown from the bespeak where the power informant is received from the battery as farthest as each ground point. (All circuit diagrams are shown with the switches in the Hit berth.)

When troubleshooting any problem, first understand the operation of the racing circuit where the problem was heard (see System Circuit section), the power reference supply power to it circuit (see Power Source section), and the ground points (see Ground Point section). See the System Outline to understand the circuit mental process.

When the circuit operation is appreciated, Menachem Begin troubleshooting of the trouble circuit to isolate the cause. Use Relay Localisation and Electrical Wiring Routing sections to find each part, junction block up and wiring harness connectors, wiring harness and wiring harness connectors and ground points of each system circuit. Inside wiring for each articulation block is also provided for better understanding of connector within a junction block.

Wiring concerned each system is indicated in each system of rules lap by arrows (from_, to_). When overall connections are mandatory, meet the Boilers suit Electrical Wiring Diagram at the end of this manual.

System Draft

Current is applied at all multiplication through the STOP conflate to TERMINAL 2 of the stop lamp SW.

When the kindling SW is turned connected, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flows finished the rear lights monition short to Endmost 4 of the light failure sensor.

Stop Light Disconnection Warning

When the ignition SW is turned connected and the brake pedal is pressed (Stop lamp SW connected), if the stop light circuit is open, the current flowing from TERMINAL 7 of the light unsuccessful person sensor to TERMINALS 1, 2 changes, indeed the soft failure sensor detects the disconnectedness and the admonitory circuit of the light failure sensor is activated.

As a result, the current flows from TERMINAL 4 of the temperate failure sensor to TERMINAL 11 to GROUND and turns the rear lights cautionary light on. By pressing the brake foot pedal, the current flowing to TERMINAL 8 of the clear failure sensor keeps the warning circuit connected and holds the red light on until the ignition SW is upturned off.
