TURN SIGNAL LAMP CIRCUIT

Description

INFOID:0000000001099362

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:0000000001099363

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.

Are the turn signal lamps turned ON?

YES

>> Turn signal lamp circuit is normal.

NO

>> Refer to

EXL-225, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000001089304

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

3.

Turn the ignition switch ON.

4.

With operating the turn signal switch, check the voltage between the BCM harness connector and the
ground.

Is the measurement value normal?

YES

>> GO TO 3.

NO

>> Replace BCM. Refer to

BCS-64, "Exploded View"

.

CHECK TURN SIGNAL LAMP SHORT CIRCUIT

Check continuity between the BCM harness connector and the ground.

Does continuity exist?

YES

>> Repair the harnesses or connectors.

NO

>> GO TO 5.

5.

CHECK TURN SIGNAL LAMP GROUND OPEN CIRCUIT

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

LIGHT & RAIN SENSOR

LIGHT & RAIN SENSOR

Description

INFOID:0000000001099364

• The light & rain sensor detects the outside brightness (lux), a rain-

drop and sensor conditions. And it transmits the signals to BCM by
the light & rain sensor serial link.

• BCM controls each function depending on the signals. And it

detects the light & rain sensor serial link error and the light & rain
sensor malfunction.

Component Function Check

INFOID:0000000001099365

1.

CHECK LIGHT & RAIN SENSOR BY CONSULT-III

CONSULT-III DATA MONITOR

1.

Turn the ignition switch ON.

2.

Select "LIT-SEN FAIL" of BCM (HEADLAMP) data monitor item.

3.

Turn the lighting switch AUTO.

4.

Start the engine.

5.

Check the monitor status.

Is it displayed with "OK"?

YES

>> Light & rain sensor is normal.

NO

>> Refer to

EXL-228, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000001099366

1.

CHECK LIGHT & RAIN SENSOR POWER SUPPLY OUTPUT

1.

Turn the ignition switch OFF.

2.

Disconnect the light & rain sensor connector.

3.

Check the voltage between the light & rain sensor harness connector and the ground.

Is the measurement value normal?

YES

>> GO TO 2.

NO

>> GO TO 3.

2.

CHECK LIGHT & RAIN SENSOR SIGNAL OUTPUT

Check the voltage between the light & rain sensor harness connector and the ground.
