Diagnosis Procedure


1. CHECK MOOD LAMP (REAR DOOR ARMREST) CONTROL OUTPUT

CONSULT ACTIVE TEST
1.Turn ignition switch ON.
2.Select "MOOD LAMP" of TOTAL ILLUM C/U active test item.
3.While operating the test items, check voltage between total illumination control unit harness connector and ground.
Mood lamp (rear door armrest RH)





Mood lamp (rear door armrest LH)





Is the measurement value normal?
Fixed at 12 V-Replace the total illumination control unit.
Fixed at 0 V-GO TO 2.

2. CHECK THE SYMPTOM

Check that the lamp fixed to ON or OFF.
