BSM Indicator Light Does Not Flash While Under BSM Indicator Light-Flashing Conditions (With Light Switch Operation (Turn Signal Switch)): Notes
BSM INDICATOR LIGHT DETECTION CONDITION AND POSSIBLE CAUSE
| Description |
BSM indicator light does not flash while under BSM indicator light-flashing conditions (with combination switch operation (turn signal switch)) |
- The BSM indicator light does not flash or illuminate continuously, but the conditions to flash the BSM indicator light are satisfied (vehicle speed 10 km/h {6.2 mph} or more
, turn signal on, and vehicle in warning zone).
- BSM indicator light does not flash or illuminate continuously, but turn signals are on.
|
| Possible Causes |
NOTE:
- This malfunction symptom is basically the same as symptom "BSM indicator light does not illuminate while under BSM indicator light-illumination conditions".
- The BSM control module mistakenly recognizes a vehicle as being outside of the warning zone when it is actually inside of it.
- Radar (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 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.
- BSM control module does not receive echo-back correctly
- BSM control module (radar) malfunction
- Problem with rear bumper such as dirt on radar emitting/receiving area, application of stickers (including transparent types), repairs using putty application.
NOTE:
- Rear bumper problems such defective installation of rear bumper, excessive dirt 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
- After-market electrical parts interfere with BSM system
- BSM does not recognize vehicle speed correctly (BSM control module mistakenly recognizes vehicle speed as being within 10 km/h {6.2 mph} or more
- PCM communication error with BSM control module
- Malfunction in ABS wheel speed sensor related parts
- Malfunction in BSM indicator light related parts
- Open circuit in wiring harness between BSM indicator light and BSM control module
- Open circuit in wiring harness or poor ground between BSM control module and ground
- BSM indicator 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 start stop unit
- Communication error between start stop unit and BSM control module
- BSM control module malfunction
