3. Check continuity between the IPDM E/R harness connector (A) and the front combination lamp harness
connector (B).
4. Check continuity between the IPDM E/R harness connector (A) and the license plate lamp harness con-
nector (B)(hatchback) or (C)(sedan).
5. Check continuity between the IPDM E/R harness connector (A) and the rear combination lamp harness
connector (B).
Does continuity exist?
YES >> GO TO 4
NO >> Repair the daytime light relay, harness or connectors.
4.CHECK PARKING LAMP GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect the front combination lamp connectors, rear combination lamp connectors or license plate
lamp connectors.
3. Check continuity between the front combination lamp harness
connector terminal and ground.
4. Check continuity between the license plate lamp harness con-
nector terminal and ground.

TURN SIGNAL LAMP CIRCUIT
TURN SIGNAL LAMP CIRCUIT
DescriptionINFOID:0000000001523271
The BCM monitors inputs from the combination switch to determine when to activate the turn signals. The
BCM outputs voltage directly 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 combination meter via the CAN com-
munication 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 lamps blink at normal speed when using the hazard warning lamp.
Component Function CheckINFOID:0000000001523272
1.CHECK TURN SIGNAL LAMP
CONSULT-III
1. Select "FLASHER" of BCM (FLASHER) active test item.
2. With test items operating, check that the turn signal lamp blinks.
Does the turn signal lamp blink?
YES >> Turn signal lamp circuit is normal.
NO >> Refer to EXL-52, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000001523273
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 connector, the rear combination lamp connector and the side turn
signals.
3. Turn the ignition switch ON.
4. With the turn signal switch operating, check voltage between the BCM harness connector M20 and
ground.
Is the measurement value normal?
YES >> GO TO 3
NO >> Replace BCM.LH : Turn signal lamp LH blinking

3.CHECK TURN SIGNAL LAMP CIRCUIT FOR OPEN
1. Turn the ignition switch OFF.
2. Disconnect BCM connector.
3. Check the continuity between the BCM harness connector M20 and the front combination lamps.
4. Check the continuity between the BCM harness connector M20 and the side turn signals.
5. Check the continuity between the BCM harness connector M20 and the rear combination lamps.
Does continuity exist?
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 >> GO TO 5
5.CHECK TURN SIGNAL LAMP GROUND CIRCUIT
Check continuity between the front combination lamp, the rear combination lamp or the side turn signal and
ground.
