load carrying capacity information indicated on tire placards when vehicle weight has been increased before retail sale. This limit is the lesser of 1.5% of GVWR or 100 pounds. If the total added weight exceeds the lesser of the limit, a label must be added to the driver-side B-pillar within 25mm (1 inch) of the original tire placard.

High Voltage Battery Inspection. B. NO PASS Inspection Result: The campaign cannot currently be completed. Perform TSB 20-EE-001H as a warranty claim, then return to complete this campaign. C. PASS Inspection Result: Perform GDS software updates to the following 4 systems to update the High Voltage Battery Monitoring: a. BMS (Battery Management System) b. IGPM (Integrated Gateway Power Module) c. MCU (Motor Control Unit) d. VCULDC (Vehicle Control Unit & Low DC-DC Converter)

may be accompanied by a warning message (e.g., Coolant Supplement, Refill Inverter Coolant) in the cluster. No related DTCs are stored, and coolant level is normal in the reservoir tank. The coolant flow may be restricted by debris, causing abnormally high Electric Water Pump (EWP) speed. This TSB contains instructions for confirming high RPMs in the EWP, then using the Coolant Flushing Equipment Set to flush and clean debris from the various cooling system circuits. The coolant will be replaced with the updated Electric Vehicle Battery System Coolant (BSC-2) low-conductivity blue coolant.

The Battery Management System (BMS) software update will be performed to enhance battery diagnostics logic. Flowchart summary of the service procedure is provided on page 2 summarized as follows: Vehicles that do not have EV Warning Light On will only need the BMS software update. Certain vehicles incurring EV Warning Light On and DTC P1AA6 found stored with Freeze Frame Data Information Code 1=128 will only require the BMS Update. Certain other DTC P1AA6 Information Code 1-2 values or DTC P1AA7 to P1AAF will require the Battery System Assembly (BSA) to be replaced and then the BMS Update to be performed.

Code (DTC) P1AA6 to P1AAF found stored. The Battery Management System (BMS) software update will be performed to enhance battery diagnostics logic. The service procedure contained in TSB 23-01-073H-1 (or latest version) is summarized as follows: Vehicles that do not have EV Warning Light ON will only need the BMS software update. Certain vehicles incurring EV Warning Light ON and DTC P1AA6 found stored with Freeze Frame Data Information Code 1=128 will only require the BMS Update. Certain other DTC P1AA6 Information Code 1-2 values or DTC P1AA7 to P1AAF will require the Battery System Assembly (BSA) to be replaced and then the BMS Update to be performed.

abnormal high EWP (electric water pump) speed in certain 2020-21MY Ioniq Electric (AE EV) and 2019-22 Kona Electric (OS EV) models. Vehicle symptoms may include "Coolant supplement or Refill Inverter Coolant" warning light On. No related DTC are found stored. Normal inverter coolant reservoir tank level is confirmed. Special tools are required for this campaign to flush and clean debris from different cooling system circuits. The coolant will be replaced by updated BSC-2 low conductivity blue coolant.

Information screen of the radio head display to prevent excessive battery heat during charging. Although outside charging is preferable, this setting is very important for vehicles that are to be charged inside a building. The campaign requires taking photos by STUI or attaching photo files to the WebDCS claim submission of both the Energy Information Screen and full vehicle instrument cluster to show vehicle is in compliance.

This update is also part of the high voltage battery monitoring logic improvement by optimizing software of each system.

The changes may vary depending on vehicle type, model, and navigation system as described in this TSB.

The changes may vary depending on vehicle type, model, and navigation system. Refer to the 2024 2nd Navigation Map and Software Update Improvements section in this TSB for a list of specific changes. The software can be downloaded via Navigation Updater (NAU) and updated by USB. The NAU website is https://update.hyundai.com/US/EN/navigationUpdate. For certain models equipped with a relevant Bluelink package, the software may be downloaded and applied via OTA update.

If the protective cover is not removed correctly, there is a possibility of the rubber insert and rail spring becoming partially separated on the inner side of the wiper blade, which could lead to poor wiping performance and/or possible scratching of the windshield glass. Follow the procedure in this bulletin to properly remove the windshield wiper blade protective cover on all new wiper blades.

It provides a barrier between the paint and contaminants, such as rail dust, acid rain, and industrial fallout. In rare cases, the paint can become clouded under the PPF. These spots are the result of moisture trapped between the PPF and the paint.

For all wheel/tire balance claims, the Tire Balance Data Sheet must be fully completed including imbalance and Road Force Variation (RFV) data. The Data Sheet can be found at the end of this bulletin.
