Calibration Research Tips: Blind Spot Indicator In Side Mirrors

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 put together a series of articles that help with the repair and calibration of ADAS. Let’s take a closer look at side mirrors with blind spot indicator lights.

We often get asked if the blind spot detection system needs to be calibrated if the side mirrors are removed/installed, or replaced, due to the blind spot indicator lights located in the mirrors. The short answer is no.

Most blind spot detection systems use radar sensors mounted behind the rear bumper cover (sides) or on the quarter panel behind the rear bumper cover (sides).

These radar sensors are inputs that detect if other vehicles are in the blind spot zone at the rear of the vehicle.

The side mirrors do not contain radar sensors that allow the system to function.

The indicator lights are simply outputs that relay the message from the sensors in the rear of the vehicle that a vehicle is in your blind spot.

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.
