Blind Spot Monitoring (BSM) Warning Light Flashes While Not Under Blind Spot Monitoring (BSM) Warning Light-Flashing Conditions (No Light Switch Operation (Turn Signal Switch)) [Blind Spot Monitoring (BSM) System]: Notes
BLIND SPOT MONITORING (BSM) WARNING LIGHT FLASHES WHILE NOT UNDER BLIND SPOT MONITORING (BSM) WARNING LIGHT-FLASHING CONDITIONS (NO LIGHT SWITCH OPERATION (TURN SIGNAL SWITCH)) [BLIND SPOT MONITORING (BSM) SYSTEM] - DESCRIPTION & POSSIBLE CAUSE
| Description |
BLIND SPOT MONITORING (BSM) WARNING LIGHT FLASHES WHILE NOT UNDER BLIND SPOT MONITORING (BSM) WARNING LIGHT-FLASHING CONDITIONS (NO LIGHT SWITCH OPERATION (TURN SIGNAL SWITCH)) |
- The blind spot monitoring (BSM) warning light flashes despite not satisfying the blind spot monitoring (BSM) warning light flashing conditions (vehicle speed above 32 km/h {20 mph} or more, turn signal on, and vehicle in warning zone).
- The blind spot monitoring (BSM) warning light flashes, but the turn signals are off.

| Possible Causes |
NOTE:
- This malfunction symptom is basically the same as symptom "blind spot monitoring (BSM) warning light while not under blind spot monitoring (BSM) warning light-illumination conditions".
- 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 (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.
- After-market electrical parts interfere with BSM system
- BSM does not recognize vehicle speed correctly (blind spot monitoring (BSM) control module mistakenly recognizes vehicle speed as being above 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
- Blind spot monitoring (BSM) control module mistakenly recognizes that turn signals have been operated
- Short to ground 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
