A disparity may occur between the actual temperature and sensed temperature of the Integrated Charging Control Unit (ICCU) during high-current AC charging, predominantly in cold weather environments. If this condition occurs, the ICCU may become damaged and exhibit a MIL ‘ON’ with the DTC(s) listed below, resulting in a stopped charging session and inability to charge using Level 1 or 2 AC chargers; however, the EV battery can still be charged using Level 3 DC fast charging, and the vehicle's drivability is unaffected.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11001603-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11001603-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11001603","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"KIA","model":"EV9","year_from":2024,"year_to":2024,"match":"exact","vehicle_ids":["2024_kia_ev9"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
