HEADLAMP (HI) CIRCUIT
HEADLAMP (HI) CIRCUIT
Description
INFOID:0000000009722901
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 (3) is switched to the high beam position through the
actuator rod (2).
• 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:0000000009722902
1.
CHECK HEADLAMP (HI) OPERATION
IPDM E/R AUTO ACTIVE TEST
1.
Start IPDM E/R auto active test. Refer to
PCS-10, "Diagnosis Description"
2.
Check that the headlamp switches to the high beam.
CONSULT 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.
Does the headlamp switch to the high beam?
YES
>> Headlamp (HI) circuit is normal.
NO
>> Refer to
.
Diagnosis Procedure
INFOID:0000000009722903
1.
CHECK HEADLAMP (HI) OUTPUT VOLTAGE
CONSULT ACTIVE TEST
1.
Turn the ignition switch OFF.
2.
Disconnect the high beam solenoid 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.

Is the measurement value normal?
YES
>> GO TO 2.
NO
>> GO TO 3.
2.
CHECK HEADLAMP (HI) OPEN CIRCUIT
1.
Turn the ignition switch OFF.
2.
Disconnect IPDM E/R connector.
3.
Check continuity between the IPDM E/R harness connector and the high beam solenoid harness connec-
tor.
Does continuity exist?
YES
>> GO TO 5.
NO
>> Repair the harnesses or connectors.
3.
CHECK HEADLAMP (HI) FUSE
1.
Turn the ignition switch OFF.
2.
Check that the following fuses are not fusing.
Is the fuse fusing?
YES
>> GO TO 4.
NO
>> Replace IPDM E/R.
4.
CHECK HEADLAMP (HI) SHORT CIRCUIT
1.
Disconnect IPDM E/R connector.
2.
Check continuity between the IPDM E/R harness connector terminal and the ground.
Does continuity exist?
YES
>> Repair the harnesses or connectors. And then replace the fuse.
NO
>> Replace the fuse. (Replace IPDM E/R if the fuse is fusing again.)
