This can cause the module to continuously reboot when the key is on. This continuous rebooting may cause the module to revert to defaults and no longer be able to save.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11031549-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11031549-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11031549","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"ALTEC","model":"AT SERIES","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
