require a replacement of the Integrated Charging Control Unit (ICCU) and ICCU Fuse. At Hyundai, we are committed to providing vehicles of outstanding quality and value. In an effort to meet this commitment, the warranty coverage for the Integrated Charging Control Unit (ICCU) and ICCU Fuse Replacement has been extended to 15 years/ 180,000 miles from the date of original retail delivery or date of first use (whichever occurs first) and is valid for original and subsequent owners.

years/180,000 miles from the date of original retail delivery or date of first use (whichever occurs first) and is valid for original and subsequent owners. Follow the flowchart in Technical Service Bulletin (TSB) 26-BE-010H to check for an active or stored occurrence of any Diagnostic Trouble Code (DTC) that requires replacement of the ICCU and replace the ICCU and ICCU fuse if necessary. Some vehicles may have an active DTC that requires ICCU replacement. Please note that any vehicles under 15 years/180,000 miles are covered by this TSB, even if vehicle is within High Voltage Warranty of 10 years/120,000 miles.

the 12V battery voltage drops below the operational voltage and the Vehicle Control Unit (VCU) places the vehicle in fail-safe mode. The VCU software in this bulletin updates the maximum vehicle speeds for various levels of 12V battery voltage when the vehicle enters fail-safe mode.

require an Integrated Charge Control Unit (ICCU) replacement, such as required for DTC P1A9096 DC to DC related charging concern or for inoperative AC charging. The ICCU fuse accessible from a rear side panel of the EV Battery, should NEVER be replaced by itself prior to receiving an ICCU replacement part. The ICCU fuse should be replaced at the same time as replacing the ICCU part. o The ICCU fuse function is to protect the EV Battery from a damaged ICCU. o DTC P1B77 Power Relay Assy (PRA) damage in the EV Battery can occur when an ICCU fuse is first replaced without also replacing the ICCU together. o Vehicles with P1B77 require Techline approval for field staff involved EV Battery repair and can result in significant additional delay for customers. o Wait to receive ICCU replacement part first before also replacing the ICCU fuse on the rear side of the EV battery. This bulletin also covers how to handle a situation when the nut(s) at the rear of the ICCU fuse falls back into the battery.

This battery diagnosis function displays the various battery-related faults such as: Internal short circuit Battery deterioration Malfunction of electronic parts Insufficient battery charge Normal battery Charging defect Battery diagnosis uses the battery sensor history saved for the last 30 days and ICU diagnostic communication to track battery state of charge (SOC) and current parasitic draw history.

battery charging occurs due to an ICCU (Intelligent Charging Control Unit) fault which may set the following DTC P1A9096 DC/DC Converter Input Voltage Sensor Fault. When a fault occurs, the vehicle may enter a reduced power mode while various warning lights, an audible chime will sound, and large messaging in the vehicles instrument cluster will appear, instructing the driver to stop the vehicle. The vehicle will be inspected for a DTC P1A9096 and may require either an ICCU software update or ICCU replacement and potential fuse replacement (if fuse is blown when inspected).

The Service Procedure flow to be followed is outlined by the flowchart on Page-3. The ICCU system is to be checked by GDS for DTC P1A9096 and depending on the result, will involve either an ICCU software update, or ICCU and potential fuse replacement. Only replace the fuse after it is inspected to confirm to be blown/open.

drivers-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.
