IEB SOFTWARE UPDATE FOR IMPROVED ELECTRONIC BRAKE
FORCE DISTRIBUTION (EBD) OPERATION
(SERVICE CAMPAIGN 9B7)

 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 2025MY IONIQ 5 N (NE N) vehicles’ Integrated Electronic Booster (IEB) software
logic may disable the operation of the Electronic Brake Force Distribution (EBD) system when there is
a malfunction with the steering angle, yaw sensor or lateral acceleration sensor and illuminate the ESC
warning lamp in the instrument cluster, instead of the ABS and BRAKE warning lamps. Follow the
procedures in this bulletin to update the IEB software to enable EBD operation when there is a
malfunction with those sensors and display the ABS and BRAKE warning lamps.

Applicable Vehicles (Certain):
• 2025MY IONIQ 5 N (NE N) produced 12/18/2023 – 4/18/2024

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