4. CHECK ENCODER POWER SUPPLY
   
   
   1. Turn ignition switch OFF.
   2. Disconnect spindle unit connector.
   3. Check voltage between spindle unit harness connector and ground.

      (+)			(-)	Voltage (Approx.)
      Spindle unit
      Connector		Terminal
      LH	B70	8	Ground	Battery voltage
      RH	B162

   Is the inspection result normal?

   YES 

   GO TO STEP 6  .

   NO 

   GO TO STEP 5  .

5. CHECK ENCODER CIRCUIT 1
   
   
   1. Disconnect automatic back door control module connector.
   2. Check continuity between automatic back door control module harness connector and spindle unit harness connector.

      Connector	Terminal	Connector		Terminal
      B55	19	LH	B70	8	Yes
      	20	RH	B162

   3. Check continuity between automatic back door control module harness connector and ground.

      Automatic back door control module		Ground	Continuity
      Connector	Terminal
      B55	19		No
      	20

   Is the inspection result normal?

   YES 

   Replace automatic back door control module. Refer to REMOVAL AND INSTALLATION .

   NO 

   Repair or replace harness.

6. CHECK ENCODER CIRCUIT 2
   
   
   1. Disconnect automatic back door control module connector.
   2. Check continuity between automatic back door control module harness connector and spindle unit harness connector.

      Automatic back door control module		Spindle unit			Continuity
      Connector	Terminal	Connector		Terminal
      B55	6	LH	B70	3	Yes
      	7			10
      	8	RH	B162	3
      	9			10

   3. Check continuity between automatic back door control module harness connector and ground.

      Connector	Terminal
      B55	6		No
      	7
      	8
      	9

   Is the inspection result normal?

   YES 

   GO TO STEP 7  .

   NO 

   Repair or replace harness.

7. CHECK ENCODER CIRCUIT 3
   
   
   1. Connect automatic back door control module and spindle unit connector
   2. Check continuity between automatic back door control module harness connector and ground.

      Automatic back door control module		Ground	Voltage (Approx.)
      Connector	Terminal
      B55	21		0 V

   Is the inspection result normal?
