Low Voltage Disconnect (LVD)
Purpose
The LVD may increase battery life
and prevent unnecessary jump
start conditions by ensuring that an
unattended load does not deplete
the battery charge to a level that will
prevent you from starting your vehicle.
Operation
The LVD will disconnect non-vital
battery loads when battery voltage
drops below 12.3V for 3 minutes and
the key switch is in the ACC or OFF
position. During the last 2 minutes the
LVD will emit a slow audible beep. 30
seconds before disconnecting loads
the alarm will change to a fast beep.
The battery voltage must come back
up above a certain voltage before the
LVD will reset.
See an authorized dealer if the LVD
fails to reconnect loads during normal
operation.

NOTE
All LVD circuits are color-coded blue
on the central electrical panel cover
label.
