The following components are under the control of the battery saver relay:
^
Delayed accessory relay.
^
Overhead interior lamp with map lamps.
^
Overhead interior lamp switch.
^
Interior lamp relay coil.
The battery saver relay becomes active (relay coil is energized) when the GEM is in the awake mode, and is deactivated (relay coil is de-energized) when
the GEM is in the sleep mode.
The battery saver will remain active until the ignition state is not ACC or RUN and 45 minutes have passed since the last active input. At that time, the
relay will be deactivated and power to the above circuits will terminate.
Five minutes after the battery saver relay has become deactivated, the GEM will go into a lower power state known as sleep mode. In the sleep mode,
the GEM will deactivate all outputs and will monitor only select inputs.
