Blind Spot Monitoring (BSM) Warning Light Illuminates While Not Under Light-Illumination Conditions [Blind Spot Monitoring (BSM) System]: Notes

BSM WARNING LIGHT ILLUMINATES WHILE NOT UNDER LIGHT-ILLUMINATION CONDITIONS (BSM SYSTEM) - POSSIBLE CAUSE

Description	BLIND SPOT MONITORING (BSM) WARNING LIGHT ILLUMINATES WHILE NOT UNDER LIGHT-ILLUMINATION CONDITIONS
Description	The blind spot monitoring (BSM) warning light illuminates, but the conditions to illuminate the blind spot monitoring (BSM) warning light are not satisfied (vehicle speed above 32 km/h {20 mph} or more, turn signals off, and vehicle in warning zone).
Possible Causes	NOTE: The system may not operate normally under the following conditions: The rear bumper near the blind spot monitoring (BSM) control module has become deformed. Snow, ice or mud adheres to the blind spot monitoring (BSM) control module on the rear bumper Under bad weather conditions such as rain, snow and fog. Stationary objects on a road or a road side such as small, two-wheeled vehicles, bicycles, pedestrians, animals, and shopping carts. Vehicle shapes which do not reflect radar waves well such as empty trailers with a low vehicle height and sports cars. Turn off the system while pulling a trailer or while an accessory such as a bicycle carrier is installed to the rear of the vehicle. Otherwise, the radio waves emitted by the radar will be blocked causing the system to not operate normally. The blind spot monitoring (BSM) control module recognizes a vehicle as being inside the warning zone when it is actually outside of it. Radar (blind spot monitoring (BSM) control module integrated) is emitted outside of warning zone (deviates from warning zone) Damage, deformity or looseness to installation bracket or vehicle frame (including moderate impacts) Malfunction in steering angle signal (instrument cluster or EPS control module malfunction) Problem with rear bumper such as soiling to radar emitting/receiving area, application of stickers (including transparent types), repairs using putty application. After-market electrical parts interfere with blind spot monitoring (BSM) system Malfunction in blind spot monitoring (BSM) warning light related parts Short to power supply circuit in wiring harness between blind spot monitoring (BSM) control module and blind spot monitoring (BSM) warning light
