Diagnosis Procedure: Notes

WARNING: This page is about a different car, the 2009 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

CHECK AMBIENT SENSOR CIRCUITS BETWEEN COMBINATION METER AND IPDM E/R

Disconnect combination meter connector M24 and IPDM E/R connector E18.

Check continuity between combination meter harness connector M24 (A) terminals 18, 20 and IPDM E/R harness connector E18 (B) terminals 20 and 21.

TERMINALS CONTINUITY REFERENCE

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

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

TERMINALS CONTINUITY REFERENCE

A		Continuity
Connector	Terminal	Continuity
M24	18	No
M24	20	No

Is the inspection result normal?

YES: GO TO 2

NO: Repair harness or connector.

CHECK AMBIENT SENSOR CIRCUITS BETWEEN IPDM E/R AND AMBIENT SENSOR

Disconnect IPDM E/R connector E201 and ambient sensor connector E211.

Check continuity between IPDM E/R harness connector E201 (A) terminals 99, 100 and ambient sensor harness connector E211 terminals 1 and 2.

TERMINALS CONTINUITY REFERENCE

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