This may occur several times until the coil warms or until the ambient temperatures rise above a threshold. The customer should request a firmware update to remedy the issue.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10239635-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10239635-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10239635","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"ALTEC","model":"AERIAL DEVICE","year_from":2021,"year_to":2022,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
