BSM Indicator Light Flashes While Not Under BSM Indicator Light-Flashing Conditions (No Light Switch Operation (Turn Signal Switch)): Notes
BSM INDICATOR LIGHT DETECTION CONDITION AND POSSIBLE CAUSE
| Description |
BSM indicator light flashes while not under BSM indicator light-flashing conditions (no combination switch operation (turn signal switch) |
- The BSM indicator light flashes despite not satisfying the BSM indicator light flashing conditions (vehicle speed 10 km/h {6.2 mph} or more
, turn signal on, and vehicle in warning zone)).
- The BSM indicator light flashes, but the turn signals are off.
|
| Possible Causes |
NOTE:
- This malfunction symptom is basically the same as symptom "BSM indicator light while not under BSM indicator light-illumination conditions".
- BSM control module recognizes a vehicle as being inside the warning zone when it is actually outside of it.
- Radar (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 start stop unit and BSM control module, or EPS control module malfunction).
- Problem with rear bumper such as dirt on 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 (BSM control module mistakenly recognizes vehicle speed as being 10 km/h {6.2 mph} or more
- PCM communication error with BSM control module
- Malfunction in ABS wheel speed sensor related parts
- 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 start stop unit
- Communication error between start stop unit and BSM control module
- BSM control module malfunction
