Automatic Headlight Systems: Other Nissan Altima L31

BATTERY SAVER CONTROL

When the combination switch (lighting switch) is in the "AUTO" position, and the ignition switch is turned from "ON" or "ACC" to "OFF", and one of the doors is opened, the battery saver feature is activated.

Under this condition, the headlights remain illuminated for 5 minutes, unless the combination switch (lighting switch) position is changed. If the combination switch (lighting switch) position is changed, then the headlights are turned "OFF".

SHUT OFF DELAY

When the ignition switch is turned from "ON" to "OFF" while the auto light system is activated and the headlights are illuminated, the shut off delay feature is activated. Under this condition, the BCM no longer receives a voltage signal at terminal No. 35, and this starts the auto light shut off delay timer. The shut off delay timer is active until one of the doors is opened, or the combination switch (lighting switch) position is changed. If one of the doors is opened, the shut off delay feature is deactivated, and the battery saver control feature is activated. If the combination switch (lighting switch) position is changed, the headlights are turned off.
