HEADLAMP (HI) CIRCUIT
HEADLAMP (HI) CIRCUIT
Description
INFOID:0000000001712377
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 lamps to
the headlamp high beam.
Component Function Check
INFOID:0000000001712378
1.
CHECK HEADLAMP (HI) OPERATION
WITHOUT CONTULT-III
1.
Start IPDM E/R auto active test. Refer to
PCS-10, "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 the test item operating, check that the headlamp switches to high beam.
Does the headlamp switch to high beam?
YES
>> Headlamp (HI) circuit is normal.
NO
>> Refer to
.
Diagnosis Procedure
INFOID:0000000001712379
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
1.
Turn the ignition switch OFF.
2.
Disconnect the front combination lamp connector E11 or E107.
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.
Are the voltage readings as specified?
YES
>> GO TO 4
NO
>> GO TO 3
HI
: Headlamp switches to the high beam.
OFF
: Headlamp OFF
