This is caused by improper control logic of the gateway unit (GWU). To eliminate this concern, the logic of the GWU has been changed so that a failure determination is not made unless a signal of the brake fluid level sensor lowering has been continued for more than 5 seconds. NOTE: - This modification is only to prevent the warning message displayed in the center display due to changes in the fluid level. Therefore, the brake warning light may be still momentarily illuminated in the instrument cluster when the fluid level fluctuates by vehicle movement. - If the brake system warning light still stays on, the brake fluid amount may be low. In that case, diagnose the vehicle according to the instructions on MGSS.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10222569-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10222569-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10222569","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-5","year_from":2021,"year_to":2022,"match":"exact","vehicle_ids":["2021_mazda_cx-5","2022_mazda_cx-5"]},{"make":"MAZDA","model":"CX-9","year_from":2021,"year_to":2022,"match":"exact","vehicle_ids":["2021_mazda_cx-9","2022_mazda_cx-9"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
