         LH		4	B25

         Trunk lid side

         IPDM E/R			Rear combination lamp (trunk lid side)		Continuity
         Connector		Terminal	Connector	Terminal
         RH	E47	17	B75	1	Yes
         LH		4	B88

   Is the inspection result normal?

   YES >>

   GO TO 4.

   NO >>

   Repair or replace harness.

4. CHECK TAIL LAMP GROUND CIRCUIT

   1. Check continuity between each rear combination lamp harness connector and ground.

      Body side

      Rear combination lamp (body side)			—	Continuity
      Connector		Terminal
      RH	B42	4	Ground	Yes
      LH	B25

      Trunk lid side

      Rear combination lamp (trunk lid side)			—	Continuity
      Connector	Terminal	Terminal
      RH	B75	4	Ground	Yes
      LH	B88

   Is the inspection result normal?

   YES >>

   Rear combination lamp (body side): Replace corresponding rear combination lamp (body side) bulb. Refer to Bulb Replacement.

   YES >>

   Rear combination lamp (trunk lid side): Replace corresponding rear combination lamp (trunk lid side) bulb. Refer to Removal and Installation.

   NO >>

   Repair or replace harness.

5. CHECK TAIL LAMP POWER SUPPLY CIRCUIT (SHORT TO GROUND)

   1. 1. Ignition switch OFF

      2. Turn lighting switch OFF.

      3. Disconnect the following connectors:

         • IPDM E/R

         • Rear combination lamp LH (body side)

         • Rear combination lamp LH (trunk lid side)
