Diagnosis Procedure - With Daytime Light System

INFOID:0000000006709933

Regarding Wiring Diagram information, refer to 

EXL-100, "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 connector, door mirror connector (if equipped with turn signals in

the mirrors) and the rear combination lamp connector.

3. Turn the ignition switch ON.

4. With turn signal switch operating, check the voltage between the front combination lamp harness connec-

tor and ground.

5. With turn signal switch operating, check the voltage between the rear combination lamp harness connec-

tor and ground.
