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

SUBJECT:

 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) and 2023-2024MY IONIQ 6 (CE1) 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

NOTICE
To avoid any potential damage to IONIQ vehicles, this service campaign can only be performed
at IONIQ certified dealers.
