YES

>> Replace IPDM E/R. Refer to 

PCS-35, "Removal and

Installation"

.

NO

>> Repair the harnesses or connectors.

4.

CHECK FRONT COMBINATION LAMP (HI) GROUND CIRCUIT

Check continuity between the front combination lamp harness con-

nector terminal and ground.

Does continuity exist?

YES

>> Inspect the headlamp bulb.

NO (Except RH with DTRL)>>Repair the harness.

NO (RH with DTRL)>>GO TO 5.

5.

CHECK CONTINUITY BETWEEN FRONT COMBINATION LAMP RH (HI) AND DAYTIME LIGHT RELAY

1. Disconnect daytime light relay connector.

2. Check continuity between front combination lamp RH harness connector and daytime light relay harness

connector.

Does continuity exist?

YES

>> GO TO 6.

NO

>> Repair the harness or connector.

CHECK DAYTIME LIGHT RELAY GROUND CIRCUIT

Check continuity between daytime light relay harness connector and ground.

Does continuity exist?

YES

>> GO TO 7.

NO

>> Repair the harness or connector.

7.

CHECK DAYTIME LIGHT RELAY FUSE

1. Turn the ignition switch OFF.

2. Check that the following fuse is not open.

Is the fuse open?

YES

>> Replace the fuse after repairing the affected circuit.

NO

>> GO TO 8.

8.

CHECK DAYTIME LIGHT RELAY CIRCUIT FOR OPEN

1. Disconnect IPDM E/R connector E18 and E201.

2. Check continuity between the IPDM E/R harness connector and the daytime light relay harness connec-

tor.

Does continuity exist?

YES

>> GO TO 9

NO

>> Repair the harnesses or connectors.

9.

CHECK DAYTIME LIGHT RELAY

Check daytime light relay. Refer to 

EXL-203, "Component Inspection"

.

Is the inspection result normal?

YES

>> Replace IPDM E/R. Refer to 

PCS-35, "Removal and Installation"

.

NO

>> Replace daytime light relay.

HEADLAMP (LO) CIRCUIT

Description

INFOID:0000000010051061

The IPDM E/R (intelligent power distribution module engine room) controls the headlamp low relay based on

inputs from the BCM over the CAN communication lines. When the headlamp low relay is energized, power

flows through fuses 51 and 52, located in the IPDM E/R. Power then flows to the front combination lamps to

the headlamp low beam.

Component Function Check

INFOID:0000000010051062

1.

CHECK HEADLAMP (LO) OPERATION

WITHOUT CONSULT

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

PCS-11, "Diagnosis Description"

.

2. Check that the headlamp is turned ON.

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 is turned ON.

Is the headlamp turned ON?

YES

>> Headlamp (LO) is normal.

NO

>> Refer to 

EXL-205, "Diagnosis Procedure"

.

Is the fuse open?

YES

>> Repair the harness and replace the fuse.

NO

>> GO TO 2.

2.

CHECK HEADLAMP (LO) OUTPUT VOLTAGE

CONSULT

1. Turn the ignition switch OFF.
