Blind Spot Monitoring (BSM) Warning Light Does Not Flash While Under Blind Spot Monitoring (BSM) Warning Light-Flashing Conditions (With Light Switch Operation (Turn Signal Switch)) [Blind Spot Monitoring (BSM) System]: Notes
BLIND SPOT MONITORING (BSM) WARNING LIGHT DOES NOT FLASH WHILE UNDER BLIND SPOT MONITORING (BSM) WARNING LIGHT-FLASHING CONDITIONS (WITH LIGHT SWITCH OPERATION - TURN SIGNAL SWITCH) (BLIND SPOT MONITORING SYSTEM) - POSSIBLE CAUSE
| Description |
LIND SPOT MONITORING (BSM) WARNING LIGHT DOES NOT FLASH WHILE UNDER BLIND SPOT MONITORING (BSM) WARNING LIGHT-FLASHING CONDITIONS (WITH LIGHT SWITCH OPERATION (TURN SIGNAL SWITCH)) |
- The blind spot monitoring (BSM) warning light does not flash or illuminate continuously, but the conditions to flash the blind spot monitoring (BSM) warning light are satisfied (vehicle speed above 32 km/h {20 mph} or more, turn signal on, and vehicle in warning zone).
- Blind spot monitoring (BSM) warning light does not flash or illuminate continuously, but turn signals are off.

| Possible Causes |
NOTE:
- This malfunction symptom is basically the same as symptom "Blind spot monitoring (BSM) warning light does not illuminate while under blind spot monitoring (BSM) warning light-illumination conditions".
- Rear bumper problems such defective installation of rear bumper, excessive soiling on radar emitting/receiving area, sticker adhesion (including transparent types), repairs to rear bumper using putty.
- Non-genuine bumper or paint, or installation of after-market parts negatively affecting radar echo-back ability.
- 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 mistakenly recognizes a vehicle as being outside of the warning zone when it is actually inside of it.
- Radar (blind spot monitoring (BSM) control module integrated) is not emitted inside of warning zone (unable to emit radar inside warning zone)
- Damage, deformity or looseness to installation bracket or vehicle frame (including moderate impacts).
- Malfunction in steering angle signal (communication error between rear body control module (RBCM) and blind spot monitoring (BSM) control module, 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.
- Blind spot monitoring (BSM) control module does not receive echo-back correctly
- Blind spot monitoring (BSM) control module (radar) 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
- Blind spot monitoring (BSM) does not recognize vehicle speed correctly (blind spot monitoring (BSM) control module mistakenly recognizes vehicle speed as being within 32 km/h {20 mph} or more)
- PCM communication error with blind spot monitoring (BSM) control module
- Malfunction in ABS wheel speed sensor related parts
- Malfunction in blind spot monitoring (BSM) warning light related parts
- Open circuit in wiring harness between blind spot monitoring (BSM) warning light and blind spot monitoring (BSM) control module
- Open circuit in wiring harness or poor ground between blind spot monitoring (BSM) control module and ground
- Blind spot monitoring (BSM) warning light malfunction
- Signal is not input for turn signal
- Combination switch (turn signal switch) malfunction
- Open circuit in wiring harness between combination switch (turn signal switch) and rear body control module (RBCM)
- Communication error between rear body control module (RBCM) and blind spot monitoring (BSM) control module
- Blind spot monitoring (BSM) control module malfunction
