id0903n2015700

Description | The BSM indicator light does not flash or illuminate continuously, but a turn signal is ON
• BSM warning alarm sounds but BSM indicator light does not flash • BSM warning alarm is triggered on side opposite to the direction in which turn signal is operated
Possible Causes | • Instrument cluster receives incorrect BSM warning alarm request signal ― Communication error between BSM control module and instrument cluster ― Instrument cluster malfunction

Diagnostic Procedure

Step | Inspection | Result | Action
--- | --- | --- | ---
1 | VERIFY DTCs • Retrieve DTCs from the BSM control module and instrument cluster using the M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER].) (See DTC INSPECTION [BLIND SPOT MONITORING (BSM) CONTROL MODULE CONNECTOR 10-PIN TYPE].) • Are any DTCs displayed? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [INSTRUMENT CLUSTER].) (See DTC TABLE [BLIND SPOT MONITORING (BSM) CONTROL MODULE CONNECTOR 10-PIN TYPE].)
No | Go to the next step.
2 | VERIFY BSM INDICATOR LIGHT CONDITION • Verify the BSM indicator light illumination condition while under the BSM indicator light-illumination conditions (vehicle speed 10 km/h {6.2 mph} or more, turn signals off, and vehicle in warning zone). • Does the BSM indicator light illuminate normally? | Yes | Replace the BSM control module. (See BLIND SPOT MONITORING (BSM) CONTROL MODULE REMOVAL/INSTALLATION [BLIND SPOT MONITORING (BSM) CONTROL MODULE CONNECTOR 10-PIN TYPE].)
No | Go to the symptom troubleshooting procedure, ”BSM indicator light does not illuminate while under BSM indicator light-illumination conditions”. (See BSM INDICATOR LIGHT DOES NOT ILLUMINATE WHILE UNDER BSM INDICATOR LIGHT-ILLUMINATION CONDITIONS [BLIND SPOT MONITORING (BSM) CONTROL MODULE CONNECTOR 10-PIN TYPE].)
