BSM INDICATOR LIGHT DOES NOT FLASH WHILE UNDER BSM INDICATOR LIGHT-FLASHING CONDITIONS (WITH LIGHT SWITCH OPERATION (TURN SIGNAL SWITCH)) [BLIND SPOT MONITORING (BSM)]

id0903d9015600

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 •  The detection performance of the blind spot monitoring (BSM) control module has limitations and the blind spot monitoring (BSM) system may not operate normally. For the detection performance limitations, refer to the [BLIND SPOT MONITORING (BSM) CONTROL MODULE] in the technical guide. •  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
