DTC P1A9096 CHECK FOR ICCU & FUSE REPLACEMENT & ICCU SOFTWARE UPDATE (RECALL 021G)

Description: Certain 2023-2024MY GV60 (JW1 EV), 2023-2024MY GV70 Electrified (JK1a EV), and 2023-2024MY G80 Electrified (RG3 EV) vehicles may have a condition where low 12V auxiliary battery charging occurs due to an ICCU (Integrated Charge Control Unit) fault and 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 vehicle’s instrument cluster will appear and instruct the driver to stop the vehicle.

The Service Procedure flow to be followed is outlined by the flowchart on Page-5. The ICCU system is to be checked via GDS for DTC P1A9096 and depending on the result, will involve either an ICCU software update, or ICCU and High Voltage Fuse replacement.

J2534 Diagnostic & Reprogramming - Hyundai

 

J2534 Reprogramming Software:

The Hyundai Motor America (HMA) J2534 reprogramming software allows for a common method of communication between aPC and a vehicle electronic control unit (ECU). U.S. EPA and CARB regulations mandate that all 2004 and later vehicle powertrain ECUs support emission-related reprogramming.

 

Vehicle Communication Interfaces (VCI)

The Hyundai J2534 Reprogramming and Diagnostic Tool software supports a SAE J2534-1/2 compliant passthru VCI device for use on Hyundai vehicles sold in the US. The devices, firmware, and application programming interfaces listed below have been tested by HMA and under no circumstances do we recommend the use of a non-approved J2534 device. HMA has worked closely with the following J2534 device manufacturers to ensure the hardware and software comply with all J2534-1/2 specifications.
