ELECTRICAL 147 ELECTRICAL C. Battery Saver: Battery Saver functionality is only active in Vehicle Power State OFF. Door Courtesy Lamps Battery Saver If any door is open and Ignition is OFF, the interior courtesy lamps should not switch off. The lights should be switched off after 10 minutes or when the voltage is 10.5volts. Which ever event comes earlier. If any door status change is reset the 10 minutes timer. Again interior lights are activated when vehicle battery voltage more than 11.0 Volts. Interior Lights Battery Saver The interior lights battery saver function will prevent battery drain if any interior light is inadvertently left on. This will ensure that a vehicle start is always possible as a flat battery is a major inconvenience to the user. The interior lights battery saver function controls the power supply relay for all the interior light battery feeds. The relay needs to be energized by the BCM using the Interior Lights Battery Saver output whenever any interior lights should be active. The following circuits are powered through the interior lights battery saver relay and can be disabled to prevent battery drain:  Interior courtesy lights (All three rows)  Sun visor lamp  Spot lights  Glove box light  Load/Cargo area light  Puddle/Door ajar lights The interior lights battery saver output is only deactivated when the Vehicle Power State is OFF and the Key is not in the ignition. (Indicated by the key switch status) The relay can only be deactivated after a time period. This time period varies dependent on the last vehicle operation. Vehicle Central Lock and Alarm set using Remote Key. After a successful lock and alarm set using the remote key the Interior Lights Battery Saver timer is activated for 5 minutes. After this time the interior lights Battery Saver relay is deactivated. In this state the vehicle should not contain passengers, otherwise the alarm will activate if the door is opened. If the lock and alarm operation fails for any reason (i.e. the vehicle is not locked) the battery saver timer is started for that state of vehicle. Vehicle Central Lock using Mechanical key in driver or passenger door or door pin. After a successful central lock using the mechanical key or door pin the Interior Lights Battery Saver timer is activated for 60 minutes. After this time the interior lights battery Saver relay is deactivated. In this state the vehicle may contain passengers, so the interior lights should be active for 60 minutes to allow the map reading lights or interior lights to be used. If the lock operation fails for any reason (i.e. the vehicle is not locked) the battery saver timer is not started. Vehicle unlocked and key not in ignition. After the key is removed from the ignition and the vehicle is not locked the Interior Lights Battery Saver timer is activated for 120 minutes. After this time the interior lights battery Saver relay is deactivated. In this state the vehicle may contain passengers, so the interior lights should be active for 120 minutes to allow the map reading lights or interior lights to be used. If the key is returned to the ignition barrel the battery saver timer is cancelled. Battery Saver Cancellation In all states the battery saver timer will be reinitiated according to state of the vehicle. The Interior Lights battery saver relay will be activated for any change in door status, a change in vehicle power state or actuator operation or any remote key operation or the Hazard switch operation. NOTE: Battery saver function (Relay) will be deactivated when Vehicle battery voltage is less than 10.5 Volts for 10 seconds and again activated if vehicle battery voltage more or equal than 11.0 volts. Battery Voltage Management To prevent battery drain, when the key is out of the ignition the BCM will monitor the battery voltage. When the voltage is 10.5 volt and below, the following functions will be disabled. These
