DAYTIME LIGHT RELAY CIRCUIT

Description

INFOID:0000000007355150

The BCM sends a daytime light request to the IPDM E/R via the CAN communication lines. The power flows

backward through fuse 45 located in IPDM E/R to daytime light relay 1 and LH high beam lamp to IPDM E/R,

through the high beam fuses, through the RH high beam lamp and on to ground. The high beam lamps are

wired in series which causes them to illuminate at a reduced intensity.

Diagnosis Procedure

INFOID:0000000007355151

FRONT FOG LAMP CIRCUIT

Description

INFOID:0000000007355153

The IPDM E/R (intelligent power distribution module engine room) controls the front fog lamp relay based on

inputs from the BCM via the CAN communication lines. When the front fog lamp relay is energized, power

flows from the front fog lamp relay in the IPDM E/R to the front fog lamps. 

Component Function Check

INFOID:0000000007355154

1.

CHECK FRONT FOG LAMP OPERATION

WITHOUT CONSULT

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

PCS-9, "Diagnosis Description"

.

2. Check that the front fog lamp is turned ON.

WITH CONSULT

1. Select "EXTERNAL LAMPS" of IPDM E/R active test item.

2. With operating the test items, Check that the front fog lamp is turned ON.

Is the front fog lamp turned ON?

YES

>> Front fog lamp circuit is normal.

NO

>> Refer to 

EXL-47, "Diagnosis Procedure"
