TURN SIGNAL LAMP CIRCUIT

TURN SIGNAL LAMP CIRCUIT

Description

INFOID:0000000007355159

The BCM monitors inputs from the combination switch (lighting and turn signal 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 hazard warning operation. The BCM sends a turn signal indicator request to the com-

bination 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

INFOID:0000000007355160

1.

CHECK TURN SIGNAL LAMP

WITH CONSULT

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-54, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000007355161

Regarding Wiring Diagram information, refer to 

EXL-101, "Wiring Diagram"

.

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 front combination lamp connector and rear combination lamp connector.

3. Turn the ignition switch ON.

4. With turn signal switch operating, check the voltage between the front combination lamp harness connec-

tor and ground.

YES

>> GO TO 3

NO

>> GO TO 5

3.

CHECK TURN SIGNAL LAMP CIRCUIT FOR OPEN 

1. Turn the ignition switch OFF.

2. Disconnect BCM connector M20, front combination lamp con-

nector and rear combination lamp connector.

3. Check continuity between the BCM harness connector M20 (A)

and the front combination lamps harness connector (B).

4. Check continuity between the BCM harness connector M20 (A)

and the rear combination lamp harness connector (B). 

Are continuity results as specified?

YES

>> GO TO 4

NO

>> Repair the harnesses or connectors.

4.

CHECK TURN SIGNAL LAMP SHORT CIRCUIT

Check continuity between the BCM harness connector M20 and

ground.

Does continuity exist?

YES

>> Repair the harnesses or connectors.

NO

>> Replace BCM. Refer to 

BCS-53, "Removal and Installa-

tion"

.

OPTICAL SENSOR

Description

INFOID:0000000007355162

The optical sensor converts the outside brightness (lux) to voltage and transmits the optical sensor signal to

the BCM.

Component Function Check

INFOID:0000000007355163

4. With the optical sensor illuminating, check the monitor status. 

*: Illuminates the optical sensor. The value may be less than the standard value if brightness is weak.

Is the item status normal?

YES

>> Optical sensor is normal.

NO

>> Refer to 

EXL-57, "Diagnosis Procedure"

.
