417-02 Interior Lighting: Description And Operation (page 4 of 9)

 
When the ignition switch is moved from the ignition position (II) or the auxiliary position (I) to the off position (0), the CJB 
starts a timer which automatically switch off all interior lamps when the 15 minute period has expired. 
 
Once the timer has expired and the lamps are off, any one of the following will 'wake-up' the battery saver and the interior 
lamps will function again. The timer will be restarted as soon as an input from one of the following is received by the CJB:
 

Ignition switch position changed to auxiliary (I), ignition (II) or crank (III)  
Any door, including the tailgate is opened  
Unlock request is received  
Front interior lamp switch is pressed.  

DELIVERY MODE 

Delivery mode is set at the factory on vehicles to minimise battery drain. The modes enables the switching off of non-
critical electrical components, including the interior lighting. The delivery mode feature can be cancelled by the dealer at 
pre-delivery inspection using T4. 
 

CRASH ILLUMINATION 

When a crash signal is received from the restraints control module, the central junction box activates the interior lamps 
once the vehicle speed has reduced to 5 km/h (3.1 mph). The lamps remain on until they are switched off manually or the 
crash signal no longer exists. For additional information, refer to

INTERIOR LIGHTING 

Interior lighting is lighting provided to enable the safe entry and departure from the vehicle for the driver and passengers 
in low ambient light conditions, without any manual switching of the interior lamps. 
 
NOTE :  

 
When the interior lighting system switches the interior lamps on, the central junction box ramps the lamps on up to full 
power over period of 1.3 seconds. When the system switches the lamps off, after the time-out delay period has expired, 
the central junction box fades the lamps off over a period of 2.6 seconds. 
 
The interior lighting system will illuminate the interior lamps when one of the following events occurs: 
 

The central junction box receives an unlock signal from the remote handset  
Any door is opened including the tailgate  
The ignition switch is turned from the ignition position (II) or the auxiliary position (I) to the off position (0).  

The interior lighting system will turn off the interior lamps when one of the following events occurs: 
 

Once the delay time-out timer has expired since the lamps were either activated or the last door is closed and the 
vehicle is not locked  
The ignition switch is in the off position (0) and an external lock (using the key or the remote handset) is requested 
with all doors closed  
The ignition switch is turned from the off position (0) or the auxiliary position (I) to the ignition position (II) with all 
doors closed  
The last door is closed while or after the vehicle is externally locked using the key or the remote handset  
The last door is closed when the ignition switch is in the ignition position.  

The interior lamps can be permanently switched off, preventing automatic operation when a door is opened or the vehicle 
is unlocked using the remote handset. This is achieved by pressing and holding the central switch of the 1st row interior 
lamp for 3 seconds. The interior lamps will remain off until the procedure is repeated.
