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: Notes
The interior lighting system consists of two subsystems: the interior lamps and the demand lamps.
The interior lamp subsystem consists of the approach lamps, footwell lamps, dome lamps, cargo lamp and the sliding door stepwell lamps. The smart junction box (SJB) provides the ground circuit for the dome lamps and the cargo lamp. The remaining interior lamps each have their own separate ground circuit.
The demand lamps subsystem consists of the map lamps, cargo lamp and the LH and RH vanity mirror lamps. Each of these lamps are switched individually and share a common ground circuit.
Power is supplied to the interior lamps through the SJB.
