Mazda technical service bulletin 09-031-18-3489 for 2016 Mazda CX-3.

Bulletin number

Component
Lane departure: blind spot detection
Summary
If it becomes necessary to replace the right-side Blind Spot Monitoring (BSM) control module, the configuration may fail even though the Workshop Manual procedure was performed properly. This may occur when the existing BSM control module has a hand written suffix on the label. Example: Applicable BSM control module part number DB2R-67-Y80B, where the suffix ("B") is handwritten on the module label: This concern is caused by the wrong suffix being written on the label with an older software version. To eliminate this concern, the production process has been changed.

Owners of these vehicles have filed 9 complaints in the driver assistance category.
