Calibration Research Tips: Mazda Blind Spot Sensors In Pairs
I-CAR · January 24, 2023 · Mazda
Summary
This article highlights a specific OEM requirement for certain Mazda vehicles, such as the 2021 CX-3, where the blind spot monitoring (BSM) control modules must be replaced in pairs if the right-hand module matches specific part numbers. Failure to replace both modules when specified will prevent the system from configuring and functioning properly.
What to do on the job
Always check the vehicle-specific Mazda workshop manual for BSM part number notes to determine if the blind spot sensors must be replaced in pairs before ordering parts or performing calibration.
How to use it
Use this document to justify the replacement of both left and right BSM sensors to insurers when only one side was directly damaged. If the damaged side utilizes the specified Mazda part numbers (e.g., DB2R-67Y80 or DB2R-67Y80 A), the OEM workshop manual mandates replacing the opposite side sensor to ensure successful system configuration and calibration.
