TURN SIGNAL LAMP CIRCUIT

TURN SIGNAL LAMP CIRCUIT

Description

INFOID:0000000009945153

BCM performs the high flasher operation 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:0000000009945154

1.

CHECK TURN SIGNAL LAMP

CONSULT ACTIVE TEST

1.

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

2.

With operating the test items, check that the turn signal lamps blink.

Does the turn signal lamps blink?

YES

>> Turn signal lamp circuit is normal.

NO

>> Refer to

EXL-50, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009945155

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 OPEN CIRCUIT

1.

Turn the ignition switch OFF.

2.

Disconnect BCM connector.

3.

Disconnect the front turn signal lamp connector, side turn signal lamp connector, or the rear combination
lamp connector.

4.

Check continuity between the BCM harness connector and the front turn signal lamp, side turn signal
lamp or the rear combination lamp harness connector.

OPTICAL SENSOR

Description

INFOID:0000000009945156

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

Component Function Check

INFOID:0000000009945157

1.

CHECK OPTICAL SENSOR SIGNAL BY CONSULT

CONSULT DATA MONITOR

1.

Turn the ignition switch ON.

2.

Select “OPTISEN (DTCT)” 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-53, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009945158

1.

CHECK OPTICAL SENSOR POWER SUPPLY INPUT

1.

Turn the ignition switch ON.

2.

Turn the lighting switch AUTO.

3.

Check the voltage between the optical sensor harness connector and the ground.

Is the measurement value normal?
