The following table shows the bulbs used for the interior lighting system and their type and specification. 
 

CENTRAL JUNCTION BOX 

The Central Junction Box (CJB) is an integrated unit located behind the instrument panel on the passenger side of the 
bulkhead. The CJB contains fuses, relays and a number of microprocessors which control the power supply and 
functionality of the interior lighting system and other vehicle systems. 
 
The interior lamps are controlled by the 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 and latching 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. 
 

Input signals 

The CJB receives the following inputs which affect the operation of the interior lamps: 
 

Ignition switch  
Door switches  
Tailgate switch  
Glove compartment lamp switch  
Unlock signal  
Interior lamp switches  
Map reading lamp switches  
Battery saver relay  
Vanity mirror lamp switches
