DEALER BATTERY MAINTENANCE
FOR PRE-DELIVERY AND IN-STOCK VEHICLES
This TSB supersedes 19-EE-006H to update Dealer Vehicle Stock Battery Maintenance Schedule
monthly maintenance requirement to 65% SOC, except ISG vehicles that require 70% SOC.
Power Fuse Switch and Dark Current Control System settings for stored vehicles are added.
Description:
This bulletin provides information on performing battery maintenance for Pre-Delivery Inspection (PDI)
and In-Stock vehicle inventory.

Dealers should inspect the battery as part of PDI within 7 days of vehicle arrival from Hyundai.

The battery should be tested with a Hyundai approved battery tester when the PDI Tablet
Application results in No Good “NG” during the AUTO CHECK function.

It is the dealer’s responsibility to ensure proper battery condition for all dealer stock vehicles
including offsite storage lots.

Battery aged maintenance should be performed regularly in accordance with the Dealer Vehicle
Stock Battery Maintenance Schedule procedures on page 2.

Perform battery maintenance per WebDCS Dealer “Aged Inventory - Blue Link Alerts”
(TSB 20-EE-003H) notifications.

Follow the vehicle preparation tips on pages 6-8 to ensure all vehicles in dealer stock are
prepared for minimal parasitic current draw on the battery during storage and to be able to
display battery state of charge (SOC) in the vehicle instrument cluster at ignition ON.

Submit the warranty claim Cadex ticket test results scanning using the GDS Battery Claim App per TSB 20-EE-002.
** Charging time will depend on battery condition and vehicle model.
*** Charging by battery charger is best for deep discharged battery <29% SOC to remove sulfation on the battery plates.
Vehicle Battery Inspection At Dealer:
Utilize the Cadex Rapid RC Tester to check battery condition within 7 days of vehicle arrival. If the
battery test result is “Charge & Retest” or “Replace Battery” in the initial check, the vehicle may qualify
for a warranty claim.

Instructions for Battery Tester Clamps Connection:
 IMPORTANT


Battery Test clamps or Charger clamps must be connected directly onto the battery
posts. Do not connect clamps to the jumper terminals in the engine compartment.
Improper connection may produce an inaccurate test result. For example, a test result
could yield “Replace Battery” although the battery is in good condition.
PROPER CONNECTION

IMPROPER CONNECTION
In certain vehicles, the battery is located in the trunk. DO NOT connect the battery tester
clamps to the remote jump start posts in the engine compartment.

NOTICE
A battery in a prolonged discharged state may adversely be damaged from internal plate
sulfation. After jump starting the vehicle, take it to the Service Department and have the battery
tested with an approved Hyundai battery tester or diagnostic charger. Take additional action
based on the test results on Page 2.

Depending on model and year, the vehicle is equipped with either:
(A) Dark Current Control System
(B) Power Fuse Switch (also known as the Shipping Fuse).
See the next 2 pages for details of each system. These systems allow for the following:
 Minimizes current draw and battery discharge at the ignition OFF state after a set sleep
period (normally 15-20 minutes after ignition OFF).
NOTE: Certain vehicle functions may not operate at this sleep state with the Power
Fuse Switch OFF, refer to the details of next page.
 Full normal vehicle operation will occur at ignition ON and engine run or Ready mode
ON conditions.
 Displays Battery SOC% on the instrument cluster at ignition ON and during engine run
or Ready mode ON when battery is charging.
NOTE:
o Most vehicles will display Battery SOC%, but a small portion of vehicles that
don’t have battery sensor will not display battery SOC on instrument cluster.
o Do not leave ignition ON in event of using a battery charger to charge the
battery. However momentarily turning ON to check Battery SOC% display
during charging is OK. Return to ignition OFF to resume full battery charger
charging.
(A) Dark Current Control System
Dark Current Control set to
It is highly recommended to set the Dark Current Control “Dealer/Shipping Mode” at vehicle
to “Dealer/Shipping Mode” using the instructions in TSB storage which helps prevent

battery discharge.
When vehicles are in dealer stock, setting the Dark
Current Control to “Dealer/Shipping Mode” minimizes
vehicle current draw and reduces battery discharge.
Dark Current Control set to “Dealer/Shipping Mode” will
not affect vehicle functionality or performance.

(B) Power Fuse Switch
It is highly recommended to turn the Power Fuse Switch
“OFF” by locating the switch under the dash fuse box,
and turning it to the “OFF” position.
Power Fuse Switch turned “OFF”
at vehicle storage which helps
prevent battery discharge.
When vehicles are in dealer stock, turning the Power
Fuse Switch “OFF” minimizes vehicle current draw and
reduces battery discharge.
When the Power Fuse Switch is “OFF”, the following
conditions occur to reduce current draw from the battery.
 Power door lock/unlock function is disabled.
 Some exterior and interior lights are disabled.
 Vehicle continuous panic alarm function will not
work, only a single beep will occur when the
keyless remote panic button is pressed.
 Some other convenient features may be disabled.
Instrument Cluster Warning
Reminder to turn Power Fuse
“ON” during test drive or customer
delivery.
NOTICE
A reminder message will appear on the instrument
cluster if the vehicle is driven with Power Fuse Switch
turned “OFF”.
There is no drivability symptoms associated with the
Power Fuse Switch in the “OFF” position.
