HEADLAMP (HI) CIRCUIT

Description

INFOID:0000000005244730

The high beam solenoid drives the mobile valve shade. And the mobile valve shade switches the high beam
and low beam of headlamp.
• When the headlamp high relay is turned ON, magnetic force is

applied to the high beam solenoid (1) by a current. The mobile
valve shade (2) is switched to the high beam position.

• When the headlamp high relay is turned OFF, the current stops.

The mobile valve shade returns to the low beam position automati-
cally.

Component Function Check

INFOID:0000000005244731

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 LAMPS" of IPDM E/R active test item.

2.

With operating the test items, check that the headlamp switches to the high beam.

NOTE:
HI/LO is repeated 1 second each when using the IPDM E/R auto active test.

Does the headlamp switch to the high beam?

YES

>> Headlamp (HI) circuit is normal.

NO

>> Refer to 

EXL-67, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000005244732

1.

CHECK HEADLAMP (HI) OUTPUT VOLTAGE

CONSULT-III ACTIVE TEST

1.

Turn the ignition switch OFF.

2.

Disconnect the front combination lamp connector.

3.

Turn the ignition switch ON.

4.

Select "EXTERNAL LAMPS" 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.
