4 H T USE THIS MNU 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. (ll circuit diagrams are shown with the switches in the FF position.) hen troubleshooting any problem, first understand the operation of the circuit where the problem was detected (see System Circuit section), the power source supplying power to that circuit (see ower Source section), and the ground points (see round oint section). See the System utline to understand the circuit operation. hen the circuit operation is understood, begin troubleshooting of the problem circuit to isolate the cause. Use elay ocation and Electrical iring outing sections to find each part, junction block and wiring harness connectors, wiring harness and wiring harness connectors, splice points, and ground points of each system circuit. Internal wiring for each junction block is also provided for better understanding of connection within a junction block. iring related to each system is indicated in each system circuit by arrows (from, to ). hen overall connections are required, see the verall Electrical iring Diagram at the end of this manual. 004 IUS (ED555U)

7 H T USE THIS MNU [N] System utline Current is applied at all times through the ST fuse to TEMIN of the stop light S. hen the ignition S is turned on, current flows from the UE fuse to TEMIN 8 of the light failure sensor, and also flows through the rear lights warning light to TEMIN 4 of the light failure sensor. Stop ight Disconnection arning hen the ignition S is turned on and the brake pedal is pressed (Stop light S on), if the stop light circuit is open, the current flowing from TEMIN 7 of the light failure sensor to TEMINS, changes, so the light failure sensor detects the disconnection and the warning circuit of the light failure sensor is activated. s a result, the current flows from TEMIN 4 of the light failure sensor to TEMIN to UND and turns the rear lights warning light on. y pressing the brake pedal, the current flowing to TEMIN 8 of the light failure sensor keeps the warning circuit on and holds the warning light on until the ignition S is turned off.
