Diagnostic Procedure

BLIND SPOT MONITORING WARNING LIGHT ILLUMINATES WHILE NOT UNDER LIGHT-ILLUMINATION CONDITIONS (BLIND SPOT MONITORING SYSTEM) DIAGNOSTIC PROCEDURE

Step	Inspection	Result	Action
1	INSPECT IF MALFUNCTION IS IN INPUT SIGNAL OR BLIND SPOT MONITORING (BSM) CONTROL MODULE Monitor the following PIDs on the suspected side of the blind spot monitoring (BSM) control module (LH) using the M-MDS. (See PID/DATA MONITOR TABLE [BLIND SPOT MONITORING (BSM) CONTROL MODULE] .) SWA_POS Are the monitoring values normal?	Yes	Go to Step 3.
1		No	Go to the next step.
2	INSPECT STEERING ANGLE SIGNAL Monitor the PID STR_ANG for the EPS control module using the M-MDS. (See PID/DATA MONITOR INSPECTION [ELECTRIC POWER STEERING (EPS)] .) Is the monitoring value normal?	Yes	Retrieve DTCs from the instrument cluster and rear body control module (RBCM) using the M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER] .) (See DTC INSPECTION [REAR BODY CONTROL MODULE (RBCM)] .)
2		No	Replace the EPS control module. (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION .)
3	INSPECT REAR BUMPER Inspect the rear bumper at the blind spot monitoring (BSM) installation area for the following: Installation condition Sticker adhesion Excessive soiling Repairs using putty Is the rear bumper condition normal?	Yes	Go to the next step.
3		No	Repair or replace malfunctioning parts, or replace the rear bumper. (See REAR BUMPER REMOVAL/INSTALLATION .)
4	VERIFY THE CONDITION OF THE BLIND SPOT MONITORING (BSM) CONTROL MODULE Remove the rear bumper. (See REAR BUMPER REMOVAL/INSTALLATION .) Inspect the blind spot monitoring (BSM) control module for the following: Looseness Damage or deformity to the bracket Distortion at vehicle installation surface Is the blind spot monitoring (BSM) control module installation condition normal?	Yes	Go to the next step.
4		No	Repair or replace the malfunctioning part.
5	VERIFY IF CAUSE OF TROUBLE IS IN AFTERMARKET ELECTRICAL PRODUCT OR ELSEWHERE Remove the after-market electrical product. Verify that the malfunction symptom recurs as stated by the customer. Does the malfunction symptom recur?	Yes	Go to the next step.
5		No	The after-market electrical product is causing the malfunction.
6	INSPECT BLIND SPOT MONITORING (BSM) CONTROL MODULE (RADAR) Perform the blind spot monitoring (BSM) radar test. (See BLIND SPOT MONITORING (BSM) RADAR TEST .) Is "TEST PASSED" displayed?	Yes	Temporary malfunction with the radar echo-back. If the same symptom recurs repeatedly, replace the blind spot monitoring (BSM) control module. (See BLIND SPOT MONITORING (BSM) CONTROL MODULE REMOVAL/INSTALLATION .)
6		No	Repair or replace malfunctioning part according to inspection result. (See BLIND SPOT MONITORING (BSM) RADAR TEST .)
