WARNING!
Do not use the Spare Battery A and B cir-
cuits or other circuits that are controlled by
the LVD to power electronic engine controls,
ABS circuits, or safety/work related lighting.
Before adding any device to the vehicle's
electrical system, consult your nearest au-
thorized dealer or read the contents of TMC
RP136. Failure to do so may cause equip-
ment damage or lead to personal injury.
NOTE
The determination of what circuits/loads that
were connected to the LVD was based upon
the recommendation from Technology and
Maintenance Council (TMC) of the Ameri-
can Trucking Association. To review the rec-
ommended practice, see TMC RP-136.
The LVD will disconnect non-vital battery
loads when battery voltage drops below
12.2V for 2 minutes and the key switch is
in the ACC or OFF position. During the
next 30 seconds, the LVD will flash the
Battery Disconnect Telltale in the Driver
Information Display. As the telltale flashes
an audio warning will also sound. During
the last 2 minutes the LVD will emit a slow
audible beep. After 2 minutes of flashing
the warning on the DPC, the LVD will shut-
off any circuit connected through the LVD
system. Even if the ignition switch is cycled
OFF and ON again, the LVD will continue
to fault until it sees battery voltage at, or
above, 12.2V.
