1. CHECK BLIND SPOT WARNING/BLIND SPOT INTERVENTION INDICATOR CIRCUIT FOR OPEN 1 
   1. Turn ignition switch OFF.
   2. Disconnect side radar harness connector and Blind Spot Warning/Blind Spot Intervention indicator harness connector.
   3. Check continuity between side radar harness connector and Blind Spot Warning/Blind Spot Intervention indicator harness connector.

      Side radar		Blind Spot Warning/Blind Spot Intervention indicator		Continuity
      Connector	Terminal	Connector	Terminal
      B416 (LH)	6	D21 (LH)	1	Yes
      B109 (RH)		D111 (RH)

   Is the inspection result normal? 

   YES: GO TO  2.

   NO: Repair the harnesses or connectors.

2. CHECK BLIND SPOT WARNING/BLIND SPOT INTERVENTION INDICATOR CIRCUIT FOR OPEN 2 

   Check continuity between Blind Spot Warning/Blind Spot Intervention indicator harness connector and ground.

   Blind Spot Warning/Blind Spot Intervention indicator		Ground	Continuity
   Connector	Terminal
   D21 (LH)	4		Yes
   D111 (RH)

   Is the inspection result normal? 

   YES: GO TO  3.

   NO: Repair the harnesses or connectors.

3. CHECK SIDE RADAR VOLTAGE OUTPUT 
   1. Connect side radar harness connector.
   2. Check voltage between Blind Spot Warning/Blind Spot Intervention indicator harness connector and ground.

      Blind Spot Warning/Blind Spot Intervention indicator		Ground	Condition	Voltage (Approx.)
      Connector	Terminal
      D21 (LH)	1		Ignition switch OFF → ON (Approx. 2 sec.)	6 V
      D111 (RH)

   Is the inspection result normal? 

   YES: Replace Blind Spot Warning/Blind Spot Intervention indicator.

   NO: Replace side radar. Refer to "REMOVAL AND INSTALLATION ".
