System Operation

When the ignition switch turns to on:

1. Two transistors are turned on with current (1) flowing in transistor 1, and current (2) in transistor 2.

2. When transistors 1 and 2 are on, the headlight relay and TNS relay turn on, and the headlights (low-beam), parking lights/taillights/license plate light illuminate.

When the ignition switch is at ON and the headlight switch is at TNS position:

1. When the headlight switch is turned to the TNS position, battery voltage from the TNS relay flows from the headlight switch to the ground, and the TNS relay is turned on.

2. When the TNS is on, the parking lights/taillights/license plate light illuminate. Also, current (1) flows in relay B, and relay B is turned on.

3. When relay B is on, the illumination light illuminates.

2. When the headlight relay and TNS relay are on, the headlights (low-beam), parking lights/taillights/license plate light illuminate. Due to the flow of current (1) in relay A are turned on.

3. When relay A turns on, and the headlights (high-beam) illuminate.
