Calibration Research Tips: Mazda Blind Spot Sensors In Pairs

Posted on 24 January 2023 | Share:

While searching for information on advanced driver assistance systems (ADAS) on an OEM repair information site, you may come across unique calibration procedures or events. These events can vary by year and model, even within a particular make. As the RTS team has been researching these systems, we have been identifying these atypical circumstances. In order to help you better understand them, we are putting together a series of articles that help with the repair and calibration of ADAS. Let’s take a look at Mazda blind spot sensors.

Some Mazda blind spot sensor replacement or removal/installation procedures have an important note that might be overlooked. Using the 2021 Mazda CX-3 as an example, lets take a look at what this note says.

Per the 2021 Mazda CX-3 Workshop Manuals ➤ i-ACTIVSENSE ➤ i-ACTIVSENSE Component Part ➤ Blind Spot Monitoring (BSM) Control Module Removal/Installation procedure:

"When replacing a blind spot monitoring (BSM) control module (RH) having any of the following part numbers, it is necessary to replace the blind spot monitoring (BSM) control module (LH) at the same time to perform the configuration normally.

  • DB2R-67Y80
  • DB2R-67Y80 A"

This means that if the right blind spot sensor has the part numbers specified; they need to be replaced in pairs. Keep in mind that not all Mazda vehicles require blind spot sensors to be replaced in pairs, so each vehicle-specific service manual should be checked.

If the Mazda being worked on requires these sensors to be replaced in pairs, and that requirement is not followed, the system will not function properly.

It is important to always follow OEM procedures for repairs and calibration. Finding this information quickly and efficiently contributes to a complete, safe, and quality repair.
