HEADLAMP (HI) CIRCUIT

HEADLAMP (HI) CIRCUIT

Description

INFOID:0000000009478464

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:0000000009478465

1.

CHECK HEADLAMP (HI) OPERATION

WITHOUT CONSULT

1. Start IPDM E/R auto active test. Refer to 

PCS-9, "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.

WITH CONSULT

1. Select "EXTERNAL LAMPS" 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 

EXL-36, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009478466

Regarding Wiring Diagram information, refer to 

EXL-72, "Wiring Diagram"

(without DTRL) or 

EXL-76, "Wiring

Diagram"

(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

>> Replace the fuse after repairing the affected circuit.

NO

>> GO TO 2

2.

CHECK HEADLAMP (HI) OUTPUT VOLTAGE
