WASHER LEVEL SWITCH SIGNAL CIRCUIT

Description

INFOID:0000000004219297

Transmits the washer level switch signal to the combination meter.

Component Function Check

INFOID:0000000004219298

1.

COMBINATION METER INPUT SIGNAL

1. Select “METER/M&A” on CONSULT-III.

2. Monitor “WASHER W/L” of “DATA MONITOR” under the following conditions.

>> Inspection End.

Diagnosis Procedure

INFOID:0000000004219299

1.

CHECK WASHER LEVEL SWITCH SIGNAL CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect combination meter connector and washer level

switch connector.

3. Check continuity between combination meter harness connector

M24 (A) terminal 29 and washer level switch harness connector

E208 (B) terminal 1.

4. Check continuity between combination meter harness connector

M24 (A) terminal 29 and ground.

Is the inspection result normal? 

YES

>> GO TO 2

NO

>> Repair harness or connector.

2.

CHECK WASHER LEVEL SWITCH GROUND CIRCUIT

Check continuity between washer fluid level switch harness connec-

tor E208 terminal 2 and ground.

Is the inspection result normal? 

YES

>> Inspection End.

NO

>> Repair harness or connector.

AMBIENT SENSOR SIGNAL CIRCUIT

Description

INFOID:0000000004219301

Transmits the ambient sensor signal to the combination meter.

Component Function Check

INFOID:0000000004219302

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-135, "Removal and Installation"

.

Diagnosis Procedure

INFOID:0000000004219303

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 con-

nector 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.
