Due to a PDC software logic error in the subject vehicle, the pre-charge resistor may become damaged if the vehicle is abnormally turned ‘OFF’ (e.g. turned ‘OFF’ while the gear selection is in ‘Neutral’). If the pre-charge resistor becomes damaged, the vehicle may not go into ‘READY’ mode. Customers may experience the illumination of the service warning light, and the vehicle may set DTC P1B7700.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11020001-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11020001-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11020001","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":["P1B77"],"topics":[],"vehicles":[{"make":"KIA","model":"EV6","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_kia_ev6"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
