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
.
Diagnosis Procedure
INFOID:0000000005244732
