VCMS SOFTWARE UPDATE – CHARGING LOGIC
(SERVICE CAMPAIGN 9B5)

This TSB supersedes 24-01-051H to include Kona Electric (SX2 EV) vehicles in the Service
Campaign.

 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.
Description: Certain 2022-2024MY IONIQ 5 (NE1), 2023-2024MY IONIQ 6 (CE1) and 20242025MY Kona Electric (SX2 EV) vehicles may exhibit a condition while charging with a 240V AC
(Level 2) charger where the vehicle experiences an interrupted charging session or a lower charging
speed. This occurs to prevent potential damage to the charging cable connection. Follow the
procedure in this TSB to update the software logic for the Vehicle Charging Management System
(VCMS), which initiates a self-restart that allows the vehicle charging to return to full capacity once
stabilized.

Applicable Vehicles (Certain):
• 2022-2024MY IONIQ 5 (NE1) produced 10/4/2023 – 12/18/2023
• 2023-2024MY IONIQ 6 (CE1) produced 12/14/2022 – 12/25/2023
