Blind Spot Monitoring (BSM) Radar Test: Notes

WARNING: This page is about a different car, the 2017 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The BSM radar test stores the radar angles in the BSM control module based on the forced emission of radar at a SST (reflector) and performing aiming based on the induced tolerance with the radar as it is currently installed and reflected from the SST (reflector).
Perform the BSM radar test when replacing the BSM control module, or the rear bumper.
As there are two BSM control modules, one each on the left and right, radar aiming is performed for each side.
The BSM radar test cannot be performed correctly if obstructions which interfere with radar emission are stuck on the BSM control modules or the rear bumper. Perform the following procedure before performing the radar test.

Verify that there is no water, dirt, sticker adhesion, or repairs done using putty application on the surface of the rear bumper, and that there is no dirt or scratches on the BSM control modules.
