What Triggers the Hyundai "Check BSD System" Message? The triggers of the Hyundai "Check BSD System" message are several. One of the most common is dirt on the rear bumpers where the manufacturer puts the sensors. Other causes include faulty hardware, code, and software update issues and a short circuit in the wiring.. To check the BSD system on a Hyundai, go to the vehicle's settings and select BSD System to view its status and make any necessary adjustments. The Blind Spot Detection (BSD) system on your Hyundai can be easily checked and adjusted through the vehicle's settings menu. This safety feature helps to alert you of any.
We have a 2016 Santa Fe Sport 2.0 T AWD Ultimate. Twice now the BSD (Blind Spot Detection) system has stopped working and a warning notice has come up on the dash screen upon starting the engine. In both cases (6 months apart) the warning has occurred after driving through very minor mud.. This was my experience with the BSD - the system has two radar sensors in the rear bumper corners, these can get misaligned if someone is bumping your car in a parking lot or if you hit a large pothole or curb - the shock will cause the sensor to become misaligned and intermittently throw the system 'alignment' out of calibration.
