Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Interior Lighting
The interior lighting system consists of the following components:
- Smart junction box (SJB)
- Dimmer control switch
- Interior/map lamps
- Cargo lamp
- Vanity mirror lamps
- Door ajar switches
- Liftgate/liftgate glass ajar switches
The interior lighting system consists of 2 subsystems:
- Interior lamps
- Demand lamps
The interior lamps are controlled by the SJB. The interior lamp subsystem consists of the interior dome lamps, and the overhead console lamps (if equipped). The SJB controls the interior lamps by providing power and ground for the lamps.
The demand lamps subsystem consists of the front map lamps, cargo lamp, and the left and right vanity mirror lamps. The SJB controls the demand lamps by providing power to the lamps.
Both subsystems use the same power supply circuit through the SJB fuse 2 (25A) and fuse 3 (25A).
