Description

Transmits the ambient sensor signal to the combination meter.

Component Function Check

1.COMBINATION METER INPUT SIGNAL

1. Select “METER/M&A” on CONSULT-III.

2. Using “OUTSIDE TEMP” on “DATA MONITOR”, compare the value of DATA MONITOR with temperature display on combination meter. DATA MONITOR and combination meter indications should be close.

Does the data monitor value approximately match the display on the combination meter? YES >> Inspection End.

NO >> Replace combination meter. Refer to MWI-176, "Removal and Installation".

Diagnosis Procedure

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 PCS-48, "Removal and Installation".

NO >> Repair harness or connector.
