2022-2024 Hyundai Ioniq 5 & 6 VCU Software Update

Hyundai has released Service Campaign 9A1, documented in Technical Service Bulletin (TSB) 23-01-067H-1, to provide a crucial Vehicle Control Unit (VCU) software update for specific electric vehicles. This update targets 2022-2023MY IONIQ 5 Electric (NE1) and 2023-2024MY IONIQ 6 Electric (CE1) models, aiming to improve overall system logic and performance.

This Service Campaign 9A1 is designed to enhance the driving experience and functionality of your electric Hyundai. Alongside the software update, owners of 2022MY IONIQ 5 vehicles will also receive an "Owner's Manual Supplement" leaflet to clarify changes and the application of the Electronic Parking Brake (EPB) system.

Key VCU Improvements

The VCU software update introduces several significant improvements to your Hyundai Ioniq 5 VCU update and Ioniq 6, optimizing various operational aspects:

• Brake Light Logic for Regenerative Braking: The updated software improves the logic for brake light actuation during regenerative braking, especially at certain deceleration speeds and when driving in i-Pedal mode, even without pressing the brake pedal.
• Enhanced i-Pedal Mode Operation: The i-Pedal system benefits from refined operational logic, providing a more intuitive and responsive driving experience.
• Electronic Parking Brake (EPB) Auto Engagement: The EPB system's logic for automatic engagement when shifting into Park and disengagement when shifting to Drive or Reverse has been improved. This function now requires specific conditions to be met, such as the door being closed and the seat belt being latched.
• Distance to Empty (DTE) Strategy: The frequency of DTE calculations is increased, now using your most recent week of driving data to determine average miles per kWh, offering a more accurate range estimate compared to the previous two-week average.
• Snow Road Surface Performance: Vehicle traction under snowy conditions is improved, enhancing safety and control in adverse weather.
• Air Conditioning Performance During AC Slow Charging: The update allows for remote or scheduled air conditioning operation during A/C charging. Previously, the system prioritized achieving and maintaining a full battery state of charge, which limited these AC functions.
• Enhanced Charging Sequence: The charging sequence has been optimized to re-enter battery charging when the battery state reaches 1.5% lower than the target state of charge. This corrects a previous issue where charging would re-enter at a 0.5% decrease, leading to excessive charging re-entry and completion notifications.
