GROUP NUMBER CAMPAIGN DATE JUNE, 2023 0B Technical Service Bulletin SUBJECT: 1B 23-01-051H-1 MODEL(S) TUCSON PLUG-IN (NX4 PHEV) & SANTA FE PLUG-IN (TM PHEV) COOLING SYSTEM CIRCUIT DEBRIS DISCHARGE AND COOLANT CHANGE (SERVICE CAMPAIGN T9F) 2B This TSB supersedes 23-01-051H to include updated information on disconnecting the 12V circuit on page 6, step 3. 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: This bulletin provides information related to the cleaning of the cooling system and coolant change to address the following problem: “Refill Inverter Coolant” warning light displayed on the cluster No DTC’s present Normal level of coolant in Inverter Reservoir Tank Measured EWP Speed > 2,800 RPM The cause of the warning light is due to increased EWP Speed due to poor flow of coolant inside the cooling circuit. The coolant in the system will be discharged and any foreign substances in the circuit will be flushed out with new coolant added in the end. STUI As outlined in the Digital Documentation Policy, all claims require VIN and Mileage validation through VCI connection or photo capture. Additionally, please ensure the repair Part photo requirement is completed according to the steps in the TSB. All claims submitted that have incomplete, illegible, or missing documentation are subject to debit. APPLICABLE VEHICLES (Certain): 2022MY Tucson Plug-in Hybrid (NX4 PHEV) equipped with 1.6L Gamma II turbocharged engines produced from 06/30/2021 – 11/01/2021. 2022MY Santa Fe Plug-in Hybrid (TM PHEV) equipped with 1.6L Gamma II turbocharged engines produced from 05/13/2021 – 09/30/2021. Circulate To: Service Manager, Warranty Manager, Service Advisors, Technicians, Fleet Repair SUBJECT: COOLING SYSTEM CIRCUIT DEBRIS DISCHARGE AND COOLANT CHANGE (SERVICE CAMPAIGN T9F) Information i To ensure proper understanding of the service procedure and equipment connections, it is recommended to view or print this bulletin in color. When working on the vehicle, ensure to disconnect the high voltage system and wear protective eye safety goggles to avoid injury from coolant leaks under pressure. To securely connect the equipment hoses, use existing coolant hose clamps at the identified locations on the vehicle as the equipment flushes coolant under pressure.

TSB #: 23-01-051H-1 Page 2 of SUBJECT: SUBJECT: COOLING SYSTEM CIRCUIT DEBRIS DISCHARGE AND COOLANT CHANGE (SERVICE CAMPAIGN T9F) COOLANT FLUSH AND FILTER EQUIPMENT OPERATING INSTRUCTIONS: 1. Air Draining (Coolant discharge) a. When discharging the remaining coolant using air, turn off the coolant pump and close the inlet valve. (If the inlet valve is opened, the air may flow back and the remaining coolant may not be recovered.) b. Equipment setting condition: i. Air ‘ON’, Pump ‘OFF’, Inlet valve ‘OFF’ c. The air pressure can be adjusted up to 3 bar to achieve desired draining performance. 2. Coolant Cleaning (Flushing and filtering of the vehicle’s coolant circuit) a. Equipment setting condition: i. Pressure 2 bar, Air ‘ON’, Pump ‘ON’, Inlet valve ‘ON’ b. TSB #: 23-01-051H-1 Page 3 of SUBJECT: SUBJECT: COOLING SYSTEM CIRCUIT DEBRIS DISCHARGE AND COOLANT CHANGE (SERVICE CAMPAIGN T9F) CAUTION ! The coolant circulation container must always have 8L (about half of the reservoir bottle) of either tap water, distilled water or coolant (blue BSC-2) that was discharged from the previous vehicle. Never use salty or light water in the coolant circulation container. For cleaning equipment, make sure to turn on the water pump first and then turn on the air. After turning on the air, visually check whether the air comes out from the end of the inlet of the equipment. When air does not come out, operate the air pressure valve to increase the pressure a little to check that air comes out and set it to 2 bar. TSB #: 23-01-051H-1 Page 4 of SUBJECT: SUBJECT: COOLING SYSTEM CIRCUIT DEBRIS DISCHARGE AND COOLANT CHANGE (SERVICE CAMPAIGN T9F) NOTICE After one cleaning operation is completed, clean the filter & filter case of the equipment with an air gun to remove foreign substances. Ensure to remove as much of the foreign substances as possible. A poorly cleaned filter can result in decreased flow rate and degrade the cleaning effect of the cleaning machine. Sludge can get stuck to the inner wall of the filter gaps, be sure to clean the filter evenly. ! WARNING When working on the high voltage system, make sure that you are familiar and comply with the "Safety Precautions, Cautions and Warnings." If you do not comply with the instructions, death or serious injury due to electric shock or leakage may occur. When working on the high voltage system, make sure to cut off the high voltage first according to the "High Voltage Cut-off Procedure." If you do not comply with the instructions, death or serious injury due to electric shock or leakage may occur. CAUTION ! Be sure to wear sufficient eye protection (safety goggles) when connecting or disconnecting hoses to the vehicle and when operating the coolant cleaning equipment until you have verified coolant discharge and cleaning is operating properly. An accidental discharge may occur and fluid may enter your eyes if you do not follow this precaution. TSB #: 23-01-051H-1 Page 5 of SUBJECT: SUBJECT: COOLING SYSTEM CIRCUIT DEBRIS DISCHARGE AND COOLANT CHANGE (SERVICE CAMPAIGN T9F) VEHICLE SERVICE PROCEDURE – DEBRIS DISCHARGE AND COOLANT CHANGE 1. Check for blue coolant inside the inverter reservoir tank. 2. Using the GDS under “Data Analysis”, monitor the initial RPM of the EWP when starting vehicle to confirm Refill Inverter Coolant warning. - Spec is 2,000 – 2,800 RPM - “Refill Inverter Coolant" displayed above 2,800 RPM. A 3. Turn off the vehicle and remove the service interlock connector (A). Disconnect the negative battery cable under the rear deck in the hatch area. 4. Remove the reservoir tank cap (B) then remove the coolant from inside the tank using the Siphon Pump Hose. - Use a bucket to catch the coolant that comes out from the discharge side of the Siphon Pump Hose as seen in the photo.
