DTC B00A0:09 (Occupant classification sensor internal signal output unstable). This concern is caused by the low voltage detection time of the occupant classification sensor (OCS) being too short during cranking, which causes detection of the DTC unnecessarily. The concern occurs more often in colder weather when greater electric current is consumed to start the vehicle. To eliminate this concern, the OCS has been modified to avoid unnecessary DTC detection.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10189820-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10189820-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10189820","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":["B00A0"],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-3","year_from":2016,"year_to":2020,"match":"exact","vehicle_ids":["2016_mazda_cx-3","2017_mazda_cx-3","2018_mazda_cx-3","2019_mazda_cx-3","2020_mazda_cx-3"]},{"make":"MAZDA","model":"CX-5","year_from":2017,"year_to":2020,"match":"exact","vehicle_ids":["2017_mazda_cx-5","2018_mazda_cx-5","2019_mazda_cx-5","2020_mazda_cx-5"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
