IONIQ 5 EV BATTERY CONDITIONING TO OPTIMIZE COLD DC CHARGING
(SERVICE CAMPAIGN T9Q)

This bulletin revises 22-01-094H to a later version of VCU Update of GDS Event 935 to improve
Eco mode driving performance. The VCU update also includes additional continuous
improvements listed on the last page.

 IMPORTANT
Dealers must perform this Service Campaign on all affected vehicles prior to customer retail
delivery and whenever an affected vehicle is in the shop for any maintenance or repair.
Access the “Vehicle Information” screen via WEBDCS to identify open campaigns.

Applicable Vehicles:
• Certain 2022MY IONIQ 5 Electric (NE1) – All Wheel Drive (AWD/4WD) Model Only
Description: This bulletin provides the information to inspect and add the Battery Conditioning function
as necessary. Some late 2022MY vehicles may already have the function. The Battery Conditioning
function optimizes the DC charging performance of the EV battery when the temperature of the battery
is below 68°F (20°C). This function allows the EV battery to preheat prior to arriving at a DC charger
site. Once software has been updated, it requires the owner of the vehicle to select a DC charger site
as a POI (point of interest) in the vehicle’s navigation system to enable the battery conditioning heating
when EV battery is below 68°F. Battery heating impact on DC charging will vary depending on the initial
battery temperature and the estimated time to arrive at the POI. If it is possible to enable battery
conditioning for longer time prior to departure, it can help to achieve the longer battery heating time
needed at very low temperatures, but will temporarily reduce range. Enabling the battery conditioning
will use battery power and temporarily reduce the driving range until charging.
The following vehicle updates need to be performed to add the Battery Conditioning function:
• BMS (Battery Management System) Software Update
• VCU (Vehicle Control Unit) Software Update
• AVN Map Software Update (only applies to certain earlier vehicles produced before Oct 2021)

Circulate To: Service Manager, Warranty Manager, Service Advisors, Technicians, Fleet Repair

SUBJECT: IONIQ 5 EV BATTERY CONDITIONING TO OPTIMIZE COLD DC CHARGING (SERVICE CAMPAIGN T9Q)

Battery Conditioning Operation (once installed in vehicle):
1. The Battery Conditioning must be enabled in the AVN display at the EV Settings Screen:

2. The Navigation System POI is set to a DC Charger Site.

3. When the Battery Module Temperature is below 68°F (20°C), then the Battery Conditioning will
activate after 1 - 2 min of heating system checks and preparation. The following splash screen
will be displayed briefly, then the winter icon will remain on the SOC display.

the part is out of warranty, submit a prior approval request for goodwill consideration prior to
performing the work.
NOTE 3: Op time includes taking STUI picture and uploading. The STUI photo must be taken as
directed. If not included, claim will be subject to debit.

STUI
This TSB includes STUI picture as a requirement. Please include the last 6 digits of the
VIN and date of repair on a piece of paper to include in the photo. Ensure the VIN and date
of repair are clearly visible. Finally, please ensure all captured pictures are completed

Service Procedure:

i

Information

ECU Update may require a long time. If a vehicle is received below 35% EV Battery SOC it may
have a 12V Battery too low, so charge the battery operating in Ready mode for at least 20 mins or
use a battery charger. Be sure to do so if this battery warning occurs during the GDS ECU update.
GDS ECU Updates must be performed in Auto Mode.
• If ECU Update starts but then fails in Auto Mode, perform the update in Manual Mode to
recover.
• Turn off ignition for 30 seconds and try Manual Mode recovery.
• If unsuccessful, re-attempt Manual Mode after disconnecting the cables from the 12V battery
terminals and performing cap discharge (connecting bar or heavy wire between
“+” to “-“ cables).

!

WARNING

GDS Vehicle Battery Voltage:
• If the voltage is below 12 volts as per the GDS warning, then select Back and run the
vehicle at least 15 minutes to reach an adequate battery state of charge to prevent an
ECU Update failure. Cycle the ignition OFF/ON before retrying ECU update again.

1. Perform the BMS Update in Auto Mode.
a. Use the Auto Mode ID Check to verify the BMS ROM ID before updating the software.

i

Information

If both the BMS and VCU Update attempts state they have already been
completed, then the vehicle may already have the Battery Conditioning
function. Confirm this at the AVN EV settings as per steps 6-7.

b. After the ECU Upgrade process shows 100% complete, cycle the ignition key to OFF for at
least 10 seconds to reset the control unit. This step is important for establishing normal
communication and to prevent system errors.
2. Perform the VCU Update in Auto Mode.
a. Use the Auto Mode ID Check to verify the VCU ROM ID before updating the software.

b. After the ECU Upgrade process shows 100% complete, cycle the ignition key to OFF for at
least 10 seconds to reset the control unit.
3. Perform an All Systems Fault Code search and erase the history of the DTC that had incidentally
occurred from the ECU update.
4. Start the vehicle in Ready mode to confirm a proper operation of the vehicle.
5. Check and perform the AVN Map Update if required. Insert STUI photo if required. If not required,
then skip to step 6.
