TURN SIGNAL LAMP CIRCUIT

TURN SIGNAL LAMP CIRCUIT

Description

INFOID:0000000003773570

BCM performs the high flasher operation (fail-safe) if any bulb or harness of the turn signal lamp circuit is
open.
NOTE:
The turn signal lamp blinks at normal speed when using the hazard warning lamp.

Component Function Check

INFOID:0000000003773571

1.

CHECK TURN SIGNAL LAMP

CONSULT-III ACTIVE TEST

1.

Select “FLASHER” of BCM (FLASHER) active test item.

2.

With operating the test items, check that the turn signal lamp is turned ON.

Is the turn signal lamp turned ON?

YES

>> Turn signal lamp circuit is normal.

NO

>> Refer to 

EXL-66, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000003773572

1.

CHECK TURN SIGNAL LAMP BULB

Check the applicable lamp bulb.

Is the bulb normal?

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 connector, the door mirror connector or the rear combination lamp
connector.

3.

OPTICAL SENSOR

Description

INFOID:0000000003773573

Optical sensor converts the outside brightness (lux) to voltage and transmits the optical sensor signal to BCM.

Component Function Check

INFOID:0000000003773574

1.

CHECK OPTICAL SENSOR SIGNAL BY CONSULT-III

CONSULT-III DATA MONITOR

1.

Turn the ignition switch ON.

2.

Select "OPTICAL SENSOR" of BCM (HEADLAMP) data monitor item.

3.

Turn the lighting switch AUTO.

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-69, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000003773575

1.

CHECK OPTICAL SENSOR POWER SUPPLY INPUT

1.
