DEALER AGED INVENTORY WEBDCS DASHBOARD FOR
BLUE LINK LOW BATTERY SOC ALERTS
This TSB supersedes TSB# 19-EE-004H to revise battery testing and charging recommendation.
 IMPORTANT
*****DEALER STOCK ONLY*****
Dealers should perform battery maintenance to all affected vehicles on WebDCS “Aged Inventory
– Blue Link Alerts” notification when a Battery State of Charge (SOC) is 50% or less.

This bulletin aids with the general battery maintenance procedure TSB 19-EE-006H, but only
applies to vehicles equipped with Blue Link SOC reporting ability.

Vehicles without Blue Link and reporting ability will not appear in WebDCS; the regular monthly
(30 days) and 3 months (90 days) maintenance procedures still apply.
Description:
This bulletin provides information on identifying dealer inventory vehicles with low Battery State of
Charge (SOC) Alerts at or below 50%. Alerted VINs can be found on the WebDCS “Aged Inventory
– Blue Link Alerts” dashboard in both the “Sales” and “Service” tabs.

The information in the WebDCS dashboard is based on the vehicle’s Engine Control Module
(ECM) calculated Battery SOC, and is transmitted via Blue Link at every engine off event.

Proper battery maintenance is required to ensure battery health. Leaving battery for extended time
in the storage lot at or below 50% SOC will negatively reduce battery health, thereby impacting
customer satisfaction (CSI).

Vehicles are equipped with a variety of advanced safety and convenience features that depends
on having a good battery health and SOC.

Battery charging should be taken as soon as possible on alerted vehicles.

Charging the battery and verifying the SOC is outlined in pages 4 - 6 of this TSB.
Applicable Vehicles: All Dealer Stock Vehicles Equipped with Blue Link
NOTICE
Per HMA warranty policy, batteries that fail during dealer storage after 7 days from arrival are the
dealer’s responsibility. It is in the dealer’s best interest to take action on these Blue Link alerts.

DEALER AGED INVENTORY WEBDCS DASHBOARD FOR
BLUELINK LOW BATTERY SOC ALERTS
Service Procedure:
SUBJECT:
Identifying Vehicles with Low Battery SOC Alerts:
1. Access Hyundai Motor America’s “Aged Inventory – Blue Link Alerts” dashboard via
WebDCS to identify dealer stock vehicles with low battery condition alerts.
2. Select the “Sales” or “Service” tab and scroll down to the subcategory to select “Aged
Inventory – Blue Link Alerts”.
Sales
Service
NOTICE
The number indicated in the red circle within the subcategory “Aged Inventory – Blue Link
Alerts” denotes how many VINs are at or below 50% SOC, without “Status” updates or the
“Requirements Not Met” status.
3. A list of dealer stock vehicles in both Sales and Service tabs with Low Battery SOC Alerts will
be displayed, which requires immediate attention to the vehicle battery SOC.

4. Prioritize your action to handle the vehicles
with the lowest Battery SOC first. These
are more likely to fail while on your lot if not
treated as soon as possible.
5. Perform battery charging utilizing either of
the methods as outlined on page 4 of this
TSB.
6. After performing the battery maintenance
perform the status update for each
individual VIN through the “Aged
Inventory – Blue Link Alerts” in either the
“Sales” or “Service” Tabs
*Refer to the chart below for the definitions
of each Status update choices.
Status Definitions:
In Progress
Complete
Sold
Requirement
Not Met

Actions are in place to perform the battery maintenance before end of current
business day.

Actions have been taken to sufficiently charge the vehicle battery over 70%
SOC.

The vehicle has been sold to a customer and is no longer in dealer stock.
 This is a system generated status due to the following:
o The vehicle was unable to achieve the proper SOC.
o The proper steps were not completed to transmit out the updated SOC
(See notice on Page 5 for further details on transmitting out the new SOC).
 No actions were taken from the previous day.
 Incorrect status selection from previous day.
NOTICE

VIN(s) will automatically be removed from WebDCS once the vehicle properly reports a SOC
value of greater than 50%. No further action will be required for the status update column in
WebDCS.

The VIN will automatically repopulate to WebDCS should the SOC value equal to or less than
50%.

It is highly recommended to charge above 70% SOC level to minimize re-alerts and a need for
recharging.

Low Battery SOC Alert Maintenance – How to Raise Battery SOC:
Use either option “A” or “B” below to charge the battery:
A. Engine Idle with Headlights On:
 During engine idle charging, instrument cluster SOC may be occasionally monitored with the
Power Fuse Switch turned “OFF”. (see page 6)
B. Automatic Regulated Battery Charger:
(NOTE: Be sure to read specific instructions of page 5).
 Must use a charger with functionality to automatically regulate current and voltage.
 The correct battery type selection, either “Flooded” or “AGM”, must be selected during battery
charging to ensure proper charging.
 Charger must have reverse polarity detection.
 The following automatic regulated battery chargers are recommended by Hyundai:
Charger:
Midtronics GR8
Associated Intellimatic ESS6008MSK
Schumacher DSR121 or DSR122
Hyundai Essential Tool
See TSB 18-EE-003
Must use DEAD BATTERY
OVERRIDE switch for a dead battery
Best used in the Boost Charge
mode

Estimated Charging Time by Either Method:
The table below is for relative comparison for deciding best method to charge based on alerted SOC level and
what is practical for each dealer situation. Charge times are only example for a large battery. Actual charge
time depends on vehicle model, battery capacity, condition, and charger used.

Specific Battery Charger Procedure Required for ECM SOC Learning:
1. Connect the positive (red) battery charger clamp to the jumper plate or tab of the battery “ + ”
positive terminal (see below diagram).
2. For the battery sensor to learn ECM Battery SOC increase during charging by battery charger, the
negative (black) battery charger clamp must be connected to the metal plate before the
battery sensor or at an unpainted chassis ground bolt, not directly to the battery terminal.
(see below picture for example).
3. After adequate time charging, run vehicle briefly for 10 seconds and turn it off to allow the ECM
Battery SOC to transmit to WebDCS updating the “Aged – Inventory Blue Link Alerts”.

NOTICE
If any of these conditions occur after charging:
 Re-alerts to WebDCS stating “Requirement Not Met”,
 Instrument cluster SOC or GDS SOC (see page 6) indicates “- -“ or “checking”
 ECM SOC % is much lower than expected.
… which could have resulted from any of the following situations:
 Charging from a deep discharged battery (29-0% ECM SOC).
 Charging directly at the battery terminals rather than with the charger black clamp connected
at the plate or tab before the vehicle’s battery sensor.
 Charging after disconnecting battery cable(s) or removing the battery to be charged outside
of the vehicle.
…Then the following steps are needed to recalibrate ECM SOC and transmit to WebDCS:
a) Vehicle needs to have rested with ignition “OFF” for at least 4 hours, battery cables
connected, doors, hood, and trunk closed and all accessories off.
b) Perform an Engine ON/OFF event with at least 10 seconds of engine running.

Verifying ECM Battery SOC:
Vehicle’s ECM Battery SOC condition may be verified by using either of the following 2 methods
based on which applies to the vehicle and is convenient for each dealer situation:
A. Instrument Cluster ECM Battery SOC
Display:




ECM’s Battery SOC can be displayed on
the instrument cluster with the ignition
switch turned “ON” and the Power Fuse
Switch is in the “OFF” position.
The Power Fuse Switch can be located
under the dash within the fuse box.
Not all vehicles can display Instrument
cluster SOC.
On most vehicles, it displays when vehicle
odometer is less than 100 miles.
NOTICE


While battery is being charged with a charger, the instrument cluster ECM SOC can be
monitored by turning the ignition “ON” briefly. DO NOT leave the ignition “ON” for an
extended period of time.
It is recommended to turn the Power Fuse Switch “OFF” when vehicles are in dealer stock to
minimize vehicle current draw and reduce battery discharge.
B. GDS ECM Current Data:

State of Charge of Battery is one of the
parameters found in the “Engine Data
Analysis” screens of the GDS display.
NOTICE
In the event of a battery that fails to take charge or hold charge, test the battery condition with
Hyundai approved Cadex tester or GR8 tester/charger.
Refer to TSB 17-EE-003 or 18-EE-003 (or newer TSBs) for detailed information.
