HEADLAMP (HI) CIRCUIT

Component Function Check

INFOID:0000000003534188

1.

CHECK HEADLAMP (HI) OPERATION

IPDM E/R AUTO ACTIVE TEST

1.

Activate IPDM E/R auto active test. Refer to 

PCS-11, "Diagnosis Description"

.

2.

Check that the headlamp switches to the high beam.

CONSULT-III ACTIVE TEST

1.

Select “EXTERNAL LAMP” of IPDM E/R active test item.

2.

With operating the test items, check that the headlamp (HI) is turned ON.

NOTE:
ON/OFF is repeated 1 second each.

Is the headlamp (HI) turned ON?

YES

>> Headlamp (HI) circuit is normal.

NO

>> Refer to 

EXL-242, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000003534189

1.

CHECK HEADLAMP (HI) OUTPUT VOLTAGE

CONSULT-III ACTIVE TEST

1.

Turn the ignition switch OFF.

2.

Disconnect the headlamp high connector.

3.

Turn the ignition switch ON.

4.

Select “EXTERNAL LAMP” of IPDM E/R active test item.

5.

With operating the test items, check the voltage between the IPDM E/R harness connector and the
ground.

Is the measurement value normal?

YES

>> GO TO 2.

NO

>> GO TO 3.

2.

CHECK HEADLAMP (HI) OPEN CIRCUIT
