TURN SIGNAL LAMP CIRCUIT

TURN SIGNAL LAMP CIRCUIT

Description

INFOID:0000000005274747

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:0000000005274748

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-48, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000005274749

Regarding Wiring Diagram information, refer to 

EXL-72, "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 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.
