LIGHTING SYSTEMS

Lights off operation
1. When the light switch is in the AUTO position the illumination level sensors in the auto light sensor (installed in
the windshield) detect the illumination level above and in front of the vehicle.
2. If the upward and forward illumination level sensor detect approx. 4,000 lux or more for 1.0 s in front of and
above the vehicle, the headlight and TNS off control signal is sent to the auto light/wiper control module.
3. The microcomputer in the auto light/wiper control module receives the control signal and turns off the current to
transistor A, causing the TNS relay to also turn off.
4. When the TNS relay turns off, the TNS also turns off.
5. The microcomputer in the auto light/wiper control module receives the control signal and turns off the current to
transistor B, causing the headlight relay (LO) to also turn off.
6. When the headlight relay (LO) turns off, the headlights (low-beam) also turn off.
Fail-Safe Function
