Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM - COUPE " or "WIRING DIAGRAM - SEDAN ".

1. CHECK AMBIENT SENSOR CIRCUITS BETWEEN COMBINATION METER AND IPDM E/R
   1. Disconnect combination meter connector M24 and IPDM E/R connector E18.
   2. Check continuity between combination meter harness connector M24 (A) terminals 18, 20 and IPDM E/R harness connector E18 (B) terminals 20 and 21.

      A		B		Continuity
      Connector	Terminal	Connector	Terminal
      M24	18	E18	21	Yes
      	20		20

   3. Check continuity between combination meter harness connector M24 (A) terminals 18, 20 and ground.

      A		Ground	Continuity
      Connector	Terminal
      M24	18		No
      	20

      Is the inspection result normal? 

      YES: GO TO 2

      NO: Repair harness or connector.

2. CHECK AMBIENT SENSOR CIRCUITS BETWEEN IPDM E/R AND AMBIENT SENSOR
   1. Disconnect IPDM E/R connector E201 and ambient sensor connector E211.
   2. Check continuity between IPDM E/R harness connector E201 (A) terminals 99, 100 and ambient sensor harness connector E211 terminals 1 and 2.

      A		B		Continuity
      Connector	Terminal	Connector	Terminal
      E201	99	E211	2	Yes
      	100		1

   3. Check continuity between IPDM E/R harness connector E201 (A) terminals 99, 100 and ground.

      A		Ground	Continuity
      Connector	Terminal
      E201	99		No
      	100

      Is the inspection result normal? 

      YES: Replace IPDM E/R. Refer to "REMOVAL AND INSTALLATION ".

      NO: Repair harness or connector.
