RCTA Indicator Light Flashes While Not Under RCTA Indicator Light-Flashing Conditions [Blind Spot Monitoring (BSM) System]: Notes

RCTA INDICATOR LIGHT FLASHES WHILE NOT UNDER RCTA INDICATOR LIGHT-FLASHING CONDITIONS (BLIND SPOT MONITORING (BSM) SYSTEM) - POSSIBLE CAUSE

Description	RCTA indicator light flashes under conditions other than flashing conditions
Description	The RCTA indicator light flashes under conditions other than the RCTA indicator light flashing conditions (R position (ATX)/R gear (MTX), and target vehicle detection).
Possible Causes	NOTE: If there is a thick moisture film (such as condensation) on the rear bumper, the blind spot monitoring (BSM) control module may not receive echo-back correctly. The blind spot monitoring (BSM) control module may not receive echo-back correctly due to the negative effect of a non-genuine bumper or paint, or installation of after-market parts. 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. Blind spot monitoring (BSM) control module mis-detects another vehicle or misestimates the time that another vehicle will reach the detection line Deviation of radar emission direction in blind spot monitoring (BSM) control module (emits radar outside of blind spot, or to adjacent lane) Damage, deformity or looseness of vehicle frame (including moderate impacts) Incorrect installation of rear bumper, soiling of radar emitting/receiving area, application of stickers (including transparent types), repairs using putty application Effect of non-genuine, after-market electronic device installation RCTA indicator light flash circuit malfunction Audio unit (with color LCD display) internal malfunction (RCTA indicator light flash circuit malfunction) Blind spot monitoring (BSM) control module (LH) internal malfunction (RCTA indicator light flash circuit malfunction) Blind spot monitoring (BSM) control module (LH) malfunction (mistaken flash request output)
