HEADLAMP (HI) CIRCUIT
HEADLAMP (HI) CIRCUIT
Description
INFOID:0000000004201489
The IPDM E/R (intelligent power distribution module engine room) controls the headlamp high relay based on
inputs from the BCM over the CAN communication lines. When the headlamp high relay is energized, power
flows through fuses 48 and 49, located in the IPDM E/R. Power then flows to the front combination lamps to
the headlamp high beam.
Component Function Check
INFOID:0000000004201490
1.
CHECK HEADLAMP (HI) OPERATION
WITHOUT CONTULT-III
1. Start IPDM E/R auto active test. Refer to
PCS-14, "Diagnosis Description"
2. 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.
CONSULT-III
1. Select "EXTERNAL LAMP" of IPDM E/R active test item.
2. With operating the test items, check that the headlamp switches to the high beam.
Does the headlamp switch to the high beam?
YES
>> Headlamp (HI) circuit is normal.
NO
>> Refer to
.
Diagnosis Procedure
INFOID:0000000004201491
1.
CHECK HEADLAMP (HI) FUSES
1. Turn the ignition switch OFF.
2. Check that the following fuses are not open.
Is the fuse open?
YES
>> Repair the harness and replace the fuse.
NO
>> GO TO 2
2.
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 LAMP" of IPDM E/R active test item.

5. With EXTERNAL LAMP ON, check the voltage between the
combination lamp connector and ground.
Is battery voltage present?
YES
>> GO TO 4
NO
>> GO TO 3
3.
CHECK HEADLAMP (HI) CIRCUIT FOR OPEN
1. Turn the ignition switch OFF.
2. Disconnect IPDM E/R connector.
3. Check continuity between the IPDM E/R harness connector and
the front combination lamp harness connector.
Does continuity exist?
YES
>> GO TO 4
NO
>> Repair the harnesses or connectors.
4.
CHECK FRONT COMBINATION LAMP (HI) GROUND CIRCUIT
1. Disconnect the front combination lamp connector.
2. Check continuity between the front combination lamp harness
connector terminal and ground.
Does continuity exist?
YES
>> Inspect the headlamp bulb.
NO
>> Repair the harness.

HEADLAMP (LO) CIRCUIT
HEADLAMP (HALOGEN)
HEADLAMP (HALOGEN) : Description
INFOID:0000000004201492
The IPDM E/R (intelligent power distribution module engine room) controls the headlamp low relay based on
inputs from the BCM over the CAN communication lines. When the headlamp low relay is energized, power
flows through fuses 51 and 52, located in the IPDM E/R. Power then flows to the front combination lamps to
the headlamp low beam.

INFOID:0000000004201493
1.
CHECK HEADLAMP (LO) OPERATION
WITHOUT CONSULT-III
1. Start IPDM E/R auto active test. Refer to
PCS-14, "Diagnosis Description"
2. Check that the headlamp is turned ON.
NOTE:
HI/LO is repeated 1 second each when using the IPDM E/R auto active test.
CONSULT-III
1. Select "EXTERNAL LAMP" of IPDM E/R active test item.
2. With operating the test items, check that the headlamp is turned ON.
Is the headlamp turned ON?
YES
>> Headlamp (LO) is normal.
NO
>> Refer to
EXL-42, "HEADLAMP (HALOGEN) : Diagnosis Procedure"

1. Turn the ignition switch OFF.
2. Check that the following fuses are not open.
Is the fuse open?
YES
>> Repair the harness and replace the fuse.
NO
>> GO TO 2
2.
CHECK HEADLAMP (LO) OUTPUT VOLTAGE
CONSULT-III
1. Turn the ignition switch OFF.
2. Disconnect the front combination lamp connector.
