HEADLAMP (HI) CIRCUIT
Description
INFOID:0000000009694060
The IPDM E/R (intelligent power distribution module engine room) controls the headlamp high relay based on
inputs from the BCM via 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 lamp LH
and RH high beams.
Component Function Check
INFOID:0000000009694061
1.
CHECK HEADLAMP (HI) OPERATION
WITHOUT CONSULT
1. Start IPDM E/R auto active test. Refer to
PCS-10, "Diagnosis Description"
(with Intelligent Key) or
(without Intelligent Key).
2. Check that the headlamp switches to the high beam.
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 high beam?
YES
>> Headlamp (HI) circuit is normal.
NO
>> Refer to
.
Diagnosis Procedure
INFOID:0000000009694062
Regarding Wiring Diagram information, 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 fuse after repairing the affected circuit.
NO
>> GO TO 2.
2.
CHECK HIGH BEAM BULB
Check the applicable high beam bulb to be sure the proper bulb standard is in use and the bulb is not open.
Is the bulb OK?
YES
>> GO TO 3.
NO
>> Replace the bulb.
3.
CHECK HEADLAMP (HI) OUTPUT VOLTAGE
1. Turn the ignition switch OFF.
2. Disconnect the front combination lamp connector E25 or E26.
3. Turn the ignition switch ON.
4. Turn the high beam headlamps ON.
5. With the high beam headlamps ON, check the voltage between the combination lamp connector and
ground.
HI
: Headlamp switches to the high beam.

HEADLAMP (HI) CIRCUIT
Is the inspection result normal?
YES
>> GO TO 5.
NO
>> GO TO 4.
4.
CHECK HEADLAMP (HI) CIRCUIT FOR OPEN
1. Turn the ignition switch OFF.
2. Disconnect IPDM E/R connector E45.
3. Check continuity between the IPDM E/R harness connector E45 and the front combination lamp harness
connector E25 or E26.
Is the inspection result normal?
YES
>> Replace IPDM E/R. Refer to
PCS-31, "Removal and Installation"
(with Intelligent Key) or
(without Intelligent Key).
NO
>> Repair or replace the harness or connector.
5.
CHECK FRONT COMBINATION LAMP (HI) GROUND CIRCUIT
Check continuity between the front combination lamp harness connector and ground.
Is the inspection result normal?
YES
>> Replace malfunctioning lamp.
NO
>> Repair or replace the harness or connector (without daytime light system).
>> GO TO 6 (with daytime light system).
6.
CHECK FRONT COMBINATION LAMP LH TO DAYTIME LIGHT RELAY 1 GROUND CIRCUIT
1. Disconnect daytime light relay 1 connector E37.
2. Check continuity between the daytime light relay 1 harness connector E37 and the front combination lamp
LH harness connector E25.
Is the inspection result normal?
YES
>> GO TO 7.
NO
>> Repair or replace the harness or connector.
7.
CHECK DAYTIME LIGHT RELAY 1 GROUND CIRCUIT
Check continuity between the daytime light relay 1 harness connector E37 and ground.
Is the inspection result normal?
YES
>> Replace daytime light relay 1.
