COMPONENT LOCATION









INTRODUCTION
The interior lamps are controlled by the Central Junction Box (CJB) and have two modes of operation: manual and automatic. In the manual mode the interior lamps can be switched on and off using the momentary switches adjacent to each lamp or disabled completely using the same switches. In the automatic mode the interior lamp functionality is controlled by the CJB on receipt of various input signals.
The CJB receives the following inputs which affect the operation of the interior lamps:
- Ignition switch
- Door latch switches
- Liftgate latch switch
- Glovebox lamp switch
- Unlock signal
- Main interior lamp switch
- Map reading lamp switches
- Delayed power off relay
- Vanity mirror lamp switches.
The driver's and passenger door puddle lamps are controlled by the driver's door module and the passenger door module respectively on receipt of Controller Area Network (CAN) signals from the CJB.
