KONA EV INSPECTION AND BMS UPDATE FOR REVISED MONITORING
LOGIC APPLICATION (SERVICE CAMPAIGN T5V)
 IMPORTANT
*****Dealer Stock and Retail Vehicles*****
Dealers must perform this Campaign on all affected vehicles prior to customer retail delivery
and whenever an affected vehicle is in the shop for any maintenance or repair.
When a vehicle arrives at the Service Department, access Hyundai Motor America's "Vehicle
Information Screen (VIS)" screen via WEBDCS to identify open Campaigns.
Description:
This bulletin provides information related to inspection of KONA Electric (OS EV) vehicles and to
perform a BMS (Battery Management System) software update to latest revised level.
 IMPORTANT
****SPECIAL PROCEDURE****
Carefully follow all steps exactly as provided by the inspection procedures since the BMS
update method will depend on the inspection result.
 Check for DTC P1AA600 prior to BMS update as it will require battery replacement.
 Inspect whether the appropriate BMS ROM ID had been installed in the past by Recall 196.
 The result of inspection of the past BMS Update’s ROM ID determines what type of GDS ECU
Upgrade method is to be used, Auto versus Manual for the BMS Update method.
 When available, you can view the associated training for this campaign in the “My Learning
Assignment” window on your home page of the Learning Portal.

Using GDS scan for DTC found stored in the BMS system. (NOTE: Do NOT clear BMS DTC)
BMS DTC Inspection Result:
 No DTC found
 DTC P1AA600
Next Action:
 Go to next Step-2
 Collect DTC screen, P1AA600 Freeze Frame
Data with Information Codes 1-6 (example
shown) and BMS Data Analysis screens.

Other DTC
Check if the Recall 196 BMS Update
was DONE in the past:
Use GDS as shown to check the BMS
ROM ID currently in the vehicle. Make a
note of it as the “Current ROM ID”.
Follow TSB 20-EE-001-2H or latest revision
for EV Battery Replacement procedures.
Proceed to Step-5 to update the BMS in Auto
Mode after the battery is replaced.
Refer to shop manual for service procedures,
then continue to Step-2.
With GDS select:
..S/W Management
…EV Battery System
… .System Identification:
Result is Recall 196 was DONE in the
past if the Current ROM ID is any of
these:



6080, 6082, 6084, 6086
6580, 6582, 6584, 6586
6780, 6782, 6784, 6786
For any other Current ROM ID value that
is not in the list above, assume the result
is Recall 196 was NOT performed.
Recall 196 Check Result:
 Recall 196 was DONE in the past
Next Action:
 Go to next Step-3


Recall 196 was NOT performed
Skip to Step-5 BMS Auto Mode Update
(Further inspection not required).

Check the Battery’s Original BMS
ROM ID:
Lift-up the vehicle and check the BMS ROM ID of the
label located at the left-upper rear side of the battery:
Check the label on the rear of the battery
for the BMS ROM ID as shown in the
example of the red box and make a note
of it as the “Original ROM ID”.
 NOTE
Ignore the HMC part number above
the BMS ROM ID. It is the Battery
System Assembly P/N, which is
different from the BMS P/N.
Do not use it for the BMS P/NO in
the next inspection step and the
BMS Update step.

Inspection whether the past Recall 196
BMS Update result was made to the
appropriate ROM ID:
Example BMS P/NO section of the BMS ROM ID
Table:
A. Locate the GDS read “Current ROM
ID” within the OLD column of the
Event #655 ROM ID Table of pages
6-10.
B
This example
section applies to
this BMS P/NO
NOTE: It will be one of the yellow
highlighted ROM ID for the past
Recall 196.
Original ROM ID .
from the battery label
should also be in the
OLD column of the
same BMS P/NO
section.
A
Locate the
.
Current ROM ID it
will be one of the
yellow highlighted
in the ROM ID
Table
B. Confirm if the “Original ROM ID” from
the battery label is also found within
the OLD column of the same BMS
P/NO section of the ROM ID Table.
ROM ID Check Result:
 Both “Current ROM ID” and
“Original ROM ID” are found in the
same BMS P/NO section of the ROM
ID Table.
Next Action:
 Recall 196 BMS Update was COMPLETED.
 Proceed to next Step-5 to perform BMS Auto
Mode Update.


The “Original ROM ID” is NOT
found together in the same BMS
P/NO section as the “Current ROM
ID”.

Recall 196 BMS Update was NOT performed
to the appropriate ROM ID in the past.
Skip to Step-6 to perform BMS Manual Mode
Update to change to the appropriate ROM ID.
