INFOID:0000000004501366

CHECK FUSE AND FUSIBLE LINK

Check if the following BCM fuse 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.

>> GO TO 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

>> Repair or replace harness.

CHECK GROUND CIRCUIT

Check continuity between BCM harness connector and ground.

Does continuity exist?

YES

>> Inspection End.

>> Repair or replace harness.

HEADLAMP (HI) CIRCUIT

Description

INFOID:0000000004216388

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:0000000004216389

CHECK HEADLAMP (HI) OPERATION

WITHOUT CONTULT-III

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

PCS-14, "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 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.

>> Refer to

EXL-39, "Diagnosis Procedure"

Diagnosis Procedure

INFOID:0000000004216390

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.

>> GO TO 2

CHECK HEADLAMP (HI) OUTPUT VOLTAGE

CONSULT-III ACTIVE TEST

1. Turn the ignition switch OFF.

2. Disconnect the front combination lamp connector.

3. Turn the ignition switch ON.

4. Select "EXTERNAL LAMP" of IPDM E/R active test item.
