INFOID:0000000010070070
Regarding Wiring Diagram information, refer to
.
1.
CHECK FUSE AND FUSIBLE LINK
Check if the following BCM fuses or fusible link are blown.
Is the fuse or fusible link blown?
YES
>> Replace the blown fuse or fusible link after repairing the affected circuit.
NO
>> GO TO 2
2.
CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM.
3. Check voltage between BCM harness connector and ground.
Is the measurement normal?
YES
>> GO TO 3
NO
>> Repair or replace harness.
3.
CHECK GROUND CIRCUIT
Check continuity between BCM harness connector and ground.
Does continuity exist?
YES
>> Inspection End.
NO
>> Repair or replace harness.

HEADLAMP (HI) CIRCUIT
Description
INFOID:0000000010051057
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:0000000010051058
1.
CHECK HEADLAMP (HI) OPERATION
WITHOUT CONSULT
1. Start IPDM E/R auto active test. Refer to
PCS-11, "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
1. Select "EXTERNAL LAMPS" of IPDM E/R active test item.
2. While operating the test item, 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-201, "Diagnosis Procedure"
.
Diagnosis Procedure
INFOID:0000000010051059
Regarding Wiring Diagram information, refer to
(With DTRL).
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 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.
