If one or more of the listed DTCs are stored in history, technicians are to perform SPS2 Hybrid/EV Battery Data Retrieval per Bulletin 25-NA-044, create a TAC case referencing the applicable P.I. number, and include the WCC obtained from the SPS data retrieval. TAC will provide further direction after engineering reviews the vehicle-specific data. This information applies only to the listed DTCs and symptom bytes and does not apply if the codes or symptom bytes differ.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11034765-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11034765-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11034765","components":[],"codes":[],"topics":[],"vehicles":[{"make":"CHEVROLET","model":"BOLT EV","year_from":2027,"year_to":2027,"match":"base","vehicle_ids":["2027_chevrolet_bolt"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
