AMBIENT SENSOR SIGNAL CIRCUIT


Diagnosis Procedure

Regarding Wiring Diagram information, refer to Coupe (coupe) or Sedan (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.





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





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.





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





Is the inspection result normal?
YES - Replace IPDM E/R. Refer to Service and Repair.
