Interior Light Symptom DiagnosisS6RW0D9204011
NOTE
• Use of SUZUKI scan tool makes it easy to check whether a faulty condition is on the input side or
output side of BCM. For checking procedure, refer to “Diagnosis Using Output Test Function of
SUZUKI Scan Tool” under “Scan Tool Data in Section 10B”.
• Check each part in the order from the top of the following list.

DRL Operation Inspection (If Equipped)S6RW0D9204012
1) Confirm that lighting switch is in OFF position.
2) Confirm that dimmer and passing switch is in low beam position.
3) Check DRL for operation as follows.
a) Turn ignition switch to ON position and check headlights remain OFF.
b) Start engine and run it at idle speed. Check headlights turn ON at low beam.
c) Switch dimmer and passing switch to high beam position and check headlights remain turning ON at low
beam.
4) If check result is not as satisfied, go to “Inspection of DRL Controller and Its Circuits (If Equipped)”.
Inspection of DRL Controller and Its Circuits (If Equipped)S6RW0D9204013
1) Confirm that lighting switch is in good condition referring to “Headlight Switch (in Lighting Switch) Inspection”.
