DTC U3000:04 will not clear and SCBS/SBS, LAS/LDWS, and/or HBC functions will not resume until the ignition switch has been turned OFF even if the temperature of the FSC cools.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10123439-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10123439-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10123439","components":[{"id":"brakes","name":"Brakes","parent":null},{"id":"driver-assistance","name":"Driver assistance","parent":null},{"id":"electrical","name":"Electrical system","parent":null},{"id":"backup-camera","name":"Backup camera","parent":"driver-assistance"}],"codes":["U3000"],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-3","year_from":2018,"year_to":2018,"match":"exact","vehicle_ids":["2018_mazda_cx-3"]},{"make":"MAZDA","model":"CX-5","year_from":2017,"year_to":2018,"match":"exact","vehicle_ids":["2017_mazda_cx-5","2018_mazda_cx-5"]},{"make":"MAZDA","model":"MAZDA3","year_from":2017,"year_to":2018,"match":"exact","vehicle_ids":["2017_mazda_mazda3","2018_mazda_mazda3"]},{"make":"MAZDA","model":"MAZDA6","year_from":2017,"year_to":2018,"match":"exact","vehicle_ids":["2017_mazda_mazda6","2018_mazda_mazda6"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
