Diagnosis Procedure

Regarding Wiring Diagram information, refer to WIRING DIAGRAM .

1. CHECK POWER SWITCH CIRCUIT - 1
   
   
   1. Turn power switch OFF.
   2. Disconnect power switch connector.
   3. Check voltage between power switch connector M33 and ground.

      Power switch		Ground	Voltage (Approx.)
      Connector	Terminal
      M33	3	-	Battery voltage

   Is the inspection normal?

   YES 

   GO TO STEP 2  .

   NO-1 

   Check 10 A fuse [No. 7, located in fuse block (J/B)].

   NO-2 

   Check harness for open or short between power switch and fuse.

2. CHECK POWER SWITCH CIRCUIT - 2
   
   
   1. Disconnect BCM connector M23.
   2. Check continuity between BCM connector M23 and power switch connector M33.

      BCM		Power switch		Continuity
      Connector	Terminal	Connector	Terminal
      M23	91	M33	7	Yes

   3. Check continuity between BCM connector M23 and ground.

      BCM		Ground	Continuity
      Connector	Terminal
      M23	91	-	No

   Is the inspection normal?

   YES 

   GO TO STEP 3  .

   NO 

   Repair or replace harness or connectors.

3. CHECK POWER SWITCH INTERNAL CIRCUIT
   
   
   1. Connect power switch connector.
   2. Check voltage between power switch connector M33 and ground.

      Power switch		Ground	Voltage (Approx.)
      Connector	Terminal
      M33	7	-	Battery voltage

   Is the inspection normal?

   YES 

   Replace BCM. Refer to REMOVAL AND INSTALLATION .

   NO 

   Replace power switch. Refer to REMOVAL AND INSTALLATION .
