HEADLAMP (HI) CIRCUIT
HEADLAMP (HI) CIRCUIT
Description
INFOID:0000000009175365
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 34 and 35, located in the IPDM E/R. Power then flows to the front combination lamps to
the headlamp high beam.
Component Function Check
INFOID:0000000009175366
1.
CHECK HEADLAMP (HI) OPERATION
WITHOUT CONSULT
1. Start IPDM E/R auto active test. Refer to
PCS-8, "Diagnosis Description"
.
2. Check that the headlamp switches to the high beam.
WITH CONSULT
1. Select EXTERNAL LAMPS of IPDM E/R active test item.
2. While 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
EXL-108, "Diagnosis Procedure"
.

Regarding Wiring Diagram - Refer to
1.
CHECK HEADLAMP (HI) FUSES
1. Turn the ignition switch OFF.
2. Check that the following fuses are not blown.
Is the fuse blown?
YES
>> Replace the blown fuse after repairing the affected circuit.
NO
>> GO TO 2.
2.
CHECK HEADLAMP (HI) OUTPUT VOLTAGE
CONSULT ACTIVE TEST
1. Turn the ignition switch OFF.
2. Disconnect the front combination lamp harness connector E233 or E238.
3. Turn the ignition switch ON.
4. Select EXTERNAL LAMPS of IPDM E/R active test item.
5. With EXTERNAL LAMP ON, check the voltage between the combination lamp harness connector and
ground.

>> Replace IPDM E/R. Refer to
PCS-32, "Removal and Installation"
.
NO
>> Repair or replace the harness or connector.
4.
CHECK FRONT COMBINATION LAMP (HI) GROUND CIRCUIT
1. Turn the ignition switch OFF.
2. Check continuity between the front combination lamp harness connector terminal 4 and ground.
Is the inspection result normal?
YES
>> Replace the headlamp bulb.
NO
>> Repair or replace the harness or connector.

HEADLAMP (LO) CIRCUIT
Description
INFOID:0000000009175368
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 36 and 37, located in the IPDM E/R. Power then flows to the front combination lamps to
the headlamp low beam.
Component Function Check
INFOID:0000000009175369
1.
CHECK HEADLAMP (LO) OPERATION
WITHOUT CONSULT
1. Start IPDM E/R auto active test. Refer to
PCS-8, "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
1. Select EXTERNAL LAMPS of IPDM E/R active test item.
2. While operating the test item, check that the headlamp is turned ON.
Is the headlamp turned ON?
YES
>> Headlamp (LO) is normal.
NO
>> Refer to
EXL-110, "Diagnosis Procedure"
.

CHECK HEADLAMP (LO) FUSES
1. Turn the ignition switch OFF.
2. Check that the following fuses are not blown.
Is the fuse blown?
YES
>> Replace the blown fuse after repairing the affected circuit.
NO
>> GO TO 2.
2.
CHECK HEADLAMP (LO) OUTPUT VOLTAGE
CONSULT
1. Turn the ignition switch OFF.
2. Disconnect the front combination lamp harness connector E232 or E237.
3. Turn the ignition switch ON.
4. Select EXTERNAL LAMPS of IPDM E/R active test item.
5. With EXTERNAL LAMP ON, check the voltage between the front combination lamp harness connector
E232 or E237 terminal 1 and ground.
