1. CHECK SECURITY INDICATOR LAMP POWER SUPPLY CIRCUIT
   
   
   1. Turn ignition switch OFF.
   2. Disconnect combination meter connector.
   3. Check voltage between combination meter harness connector and ground.

      (+)		(-)	Voltage (V)
      Combination meter
      Connector	Terminal
      M24	22	Ground	Battery voltage

   Is the inspection result normal?

   YES 

   GO TO STEP 2  .

   NO-1 

   Check 10 A fuse [No. 13, located in the fuse block (J/B)].

   NO-2 

   Check harness for open or short between combination meter and fuse.

2. CHECK SECURITY INDICATOR LAMP SIGNAL
   
   
   1. Connect combination meter connector.
   2. Disconnect BCM connector.
   3. Check voltage between BCM harness connector and ground.

      (+)		(-)	Voltage (V)
      BCM
      Connector	Terminal
      M18	18	Ground	Battery voltage

   Is the inspection result normal?

   YES 

   GO TO STEP 3  .

   NO 

   GO TO STEP 4  .

3. REPLACE BCM
   
   
   1. Replace BCM. Refer to REMOVAL AND INSTALLATION .
   2. Perform initialization of BCM and registration of all Intelligent Keys using CONSULT.

   Inspection End.

4. CHECK SECURITY INDICATOR LAMP CIRCUIT
   
   
   1. Disconnect combination meter connector.
   2. Check continuity between combination meter harness connector and BCM harness connector.

      Combination meter		BCM		Continuity
      Connector	Terminal	Connector	Terminal
      M24	6	M18	18	Yes

   3. Check continuity between combination meter harness connector and ground.

      Combination meter		Ground	Continuity
      Connector	Terminal
      M24	6		No

   Is the inspection result normal?

   YES 

   Replace combination meter. Refer to REMOVAL AND INSTALLATION .

   NO
