ODE MESSAGE — ELECTRICAL LOAD
R
EDUCTION ACTIONS — IF EQUIPPED
This vehicle is equipped with an Intelligent
Battery Sensor (IBS) to perform additional
monitoring of the electrical system and status
of the vehicle battery.
In cases when the IBS detects charging system
failure, or the vehicle battery conditions are
deteriorating, electrical load reduction actions
will take place to extend the driving time and
distance of the vehicle. This is done by reducing
power to or turning off non-essential electrical
loads.
Load reduction is only active when the engine is
running. It will display a message if there is a
risk of battery depletion to the point where the
vehicle may stall due to lack of electrical supply,
or will not restart after the current drive cycle.
When load reduction is activated, the message
“Battery Saver On Some Systems May Have
Reduced Power” will appear in the instrument
cluster.
These messages indicate the vehicle battery
has a low state of charge and continues to lose electrical charge at a rate that the charging
system cannot sustain.
NOTE:The charging system is independent from
load reduction. The charging system
performs a diagnostic on the charging
system continuously.
If the Battery Charge Warning Light is on it
may indicate a problem with the charging
system Ú
page 128.
The electrical loads that may be switched off (if
equipped), and vehicle functions which can be
affected by load reduction:
Heated Seats / Vented Seats / Heated Wheel
Rear Defroster And Heated Mirrors
HVAC System
115 Volts AC Power Inverter System
Audio and Telematics System
Loss of the battery charge may indicate one or
more of the following conditions:
The charging system cannot deliver enough
electrical power to the vehicle system
because the electrical loads are larger than the capability of charging system. The
charging system is still functioning properly.
Turning on all possible vehicle electrical
loads (e.g. HVAC to max settings, exterior and
interior lights, overloaded power outlets
+12 Volts, 115 Volts AC, USB ports) during
certain driving conditions (city driving,
towing, frequent stopping).
Installing options like additional lights,
upfitter electrical accessories, audio
systems, alarms and similar devices.
Unusual driving cycles (short trips separated
by long parking periods).
The vehicle was parked for an extended
period of time (weeks, months).
The battery was recently replaced and was
not charged completely.
The battery was discharged by an electrical
load left on when the vehicle was parked.
The battery was used for an extended period
with the engine not running to supply radio,
lights, chargers, +12 Volt portable appli
-
ances like vacuum cleaners, game consoles
and similar devices.
