FRONT FOG LAMP CIRCUIT

FRONT FOG LAMP CIRCUIT

Description

INFOID:0000000005259746

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.

PARKING LAMP CIRCUIT

Description

INFOID:0000000005259749

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

from the BCM via the CAN communication lines. When the tail lamp relay is energized, power flows through

fuse 37, located in the IPDM E/R. Power then flows to the front and rear combination lamps.

TURN SIGNAL LAMP CIRCUIT

Description

INFOID:0000000005259752

The BCM monitors inputs from the combination switch to determine when to activate the turn signals. The

BCM outputs voltage direction to the left and right turn signals during turn signal operation or both during haz-

ard warning operation. The BCM sends a turn signal indicator request to the combination meter via the CAN

communication lines. 

The BCM performs the fast flasher operation (fail-safe) if any bulb or harness of the turn signal lamp circuit is

open.

NOTE:

Turn signal lamp blinks at normal speed when using the hazard warning lamp.

Component Function Check

1.

CHECK TURN SIGNAL LAMP

CONSULT-III

1. Select "FLASHER" of BCM (FLASHER) active test item.

2. With operating the test items, check that the turn signal lamp blinks.

Does the turn signal lamp blink?

YES

>> Turn signal lamp circuit is normal.

NO

>> Refer to 

EXL-49, "Diagnosis Procedure"

.

1.

CHECK TURN SIGNAL LAMP BULB

Check the applicable lamp bulb to be sure the proper bulb standard is in use and the bulb is not open.
Is the bulb OK?

YES

>> GO TO 2

NO

>> Replace the bulb.

2.

CHECK TURN SIGNAL LAMP OUTPUT VOLTAGE

1. Turn the ignition switch OFF.

2. Disconnect the front combination lamp connectors and the rear

combination lamp connector.

3. Turn the ignition switch ON.

4. With turn signal switch operating, check the voltage between the

BCM harness connector M20 and ground.
