*1 If the auto light sensor detects that the TNS and headlights are off when the light switch is in the AUTO position, the DRL illuminates.
1. If the DRL mode operation conditions are met, the front body control module (FBCM) turns on the DRL circuit transistor.
2. When the transistor turns on, the DRL relay turns on.
3. If the DRL relay turns on, the electrical current flows in-line relative to the left/right headlight (HI) circuits and the headlights (HI) turn on at half the brightness of normal illumination.
