Interior Light System







1. INSPECT FRONT PERSONAL LIGHT SWITCH CONTINUITY
If continuity is not as specified, replace the light assembly or bulb.

2. INSPECT ROOM LIGHT CONTINUITY




a. Disconnect the connector from the room light.
b. Turn the room light switch ON, check that there is continuity between terminal 2 and body ground.




c. Turn the room light switch DOOR, check that there is continuity between terminals 1 and 2.
If continuity is not as specified, replace the light assembly or bulb.




3. INSPECT FRONT DOOR COURTESY SWITCH CONTINUITY
a. Check that there is continuity between terminals and the switch body with the switch ON (switch pin released: opened door).
b. Check that there is no continuity between terminals and the switch body with the switch OFF (switch pin pushed in: closed door).
If operation is not as specified, replace the switch.




4. INSPECT REAR DOOR COURTESY SWITCH CONTINUITY
a. Check that there is continuity between terminals and the switch body with the switch ON (switch pin released: opened door).
b. Check that there is no continuity between terminals and the switch body with the switch OFF (switch pin pushed in: closed door).
If operation is not as specified, replace the switch.




5. INSPECT LUGGAGE COMPARTMENT DOOR COURTESY SWITCH CONTINUITY
a. Check that there is continuity between terminals and the switch body with the switch ON (switch pin released: opened door).
b. Check that there is no continuity between terminals and the switch body with the switch OFF (switch pin pushed in: closed door).
If operation is not as specified, replace the switch.




6. INSPECT LUGGAGE COMPARTMENT LIGHT CONTINUITY
Using the ohmmeter, check that there is continuity between terminals.
If continuity is not as specified, replace the light assembly or bulb.
