This occurs when the blower fan is on (at any fan speed) and the transmission is in \"R\" position. The concern is caused by electrical noise from the blower fan controller circuit affecting the rear parking sensor circuit. To eliminate this concern, the harness to the rear parking sensor has been twisted to improve its tolerance to electrical noise.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10164045-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10164045-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10164045","components":[{"id":"driver-assistance","name":"Driver assistance","parent":null},{"id":"backup-camera","name":"Backup camera","parent":"driver-assistance"}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-5","year_from":2017,"year_to":2019,"match":"exact","vehicle_ids":["2017_mazda_cx-5","2018_mazda_cx-5","2019_mazda_cx-5"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
