CAMPAIGN 23-01-069G AUGUST 2023 G80 Electrified (RG3 EV) GV60 (JW1 EV) DTC P1A9096 CHECK FOR ICCU & FUSE REPLACEMENT AND ICCU SOFTWARE UPDATE (SERVICE CAMPAIGN 907G) 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 2023MY G80 Electrified (RG3 EV) and 2023-24MY GV60 (JW1 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-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 fuse replacement. Applicable Vehicles (Certain): • 2023MY G80 Electrified (RG3 EV) • 2023-24MY GV60 (JW1 EV) NOTICE This service campaign can only be performed by EV certified Genesis retailers.

Perform All Fault Search by GDS. A2. Check the ICCU system for DTC P1A9096. Is it either found as an active or history DTC? ➢ No – (DTC P1A9096 is not found stored): • Perform ICCU Software Update – see section B. (Campaign Claim 0.4 M/H) • NOTE: If any other DTC or symptom is found stored, diagnose and repair per shop manual before performing the ICCU Update. (Warranty Claim) ➢ Yes – (DTC P1A9096 is found stored): • Replace ICCU: o GV60 (JW1 EV) – see section C o G80 Electrified (RG3 EV) – see section D • Replace the Fuse – see section C8. (WARNING: Do NOT only replace fuse only at first without replacing ICCU, it will cause PRA damage) (Campaign Claim 2.1 for JW1 or 3.3 M/H for RG3) NOTICE You must initially perform the GDS ECU Update in Auto Mode. • If the ECU Update starts but then fails in Auto Mode, perform the update in Manual Mode to recover. NOTICE GDS Vehicle Battery Low Voltage Warning: The ICCU Update is a long ECU Update. If voltage is below 12 volts as per the below GDS warning, then select Back and run the vehicle for at least 30 minutes to ensure an adequate battery state of charge for reliable update results. Turn ignition back on, and then retry the ECU update again. TSB #: 23-01-069G Page 4 of 17 SUBJECT: B1. Perform the ECU Update in Auto Mode. Use the Auto Mode ID Check to verify the ECU ROM ID before updating the software. i Information Refer to TSB 15-GI-001 for additional tablet-based Mobile GDS ECU update information. B2. STUI Take a screenshot of the ECU Update Complete screen using your particular tablet’s screenshot save method and upload to STUI. B3. EXAMPLE After the ECU Upgrade process shows 100% complete, cycle the ignition key to OFF for at least 10 seconds to reset the control unit. TSB #: 23-01-069G Page 5 of 17 SUBJECT: B4. Perform an All Systems Fault Code search and erase the history of the DTC that had incidentally occurred from the ECU update. B5. Start the vehicle in Ready mode to confirm proper operation of the vehicle.
