LR3/Disco 3
The above components are protected by FETs which can detect overloads and short circuits. The FETs respond to heat
generated by increased current flow caused by a short circuit. On a normal circuit this would cause the fuse to blow,
rendering that component and circuit inoperative. The FETs respond to the heat increase and disconnect the supply to
the affected circuit. When the fault is rectified or the FET has cooled, the FET will reset and operate the circuit normally.
The following interior lamps circuits are protected by Fuse 1P (10A) in the CJB:
Glove compartment lamp
Map reading lamps
Vanity mirror lamps.
Interior Lamp Time-out
The interior lamps are controlled by a timer within the CJB which allows a 60 delay period for the lamps to remain on after
the ignition has been switched off or when the vehicle is unlocked. The following interior lamps are subject to the delay
period:
Interior lamps
Footwell lamps
Luggage compartment lamps
Puddle lamps
Ignition switch glow ring.
The delay period can be adjusted to suit the driver's requirements, refer to following section for adjustment details.
The time-out delay is activated when the CJB receives one of the following signals:
The CJB receives an unlock signal from the remote handset
Ignition switch is moved from the crank position (III) or the ignition position (II) or to the auxiliary position (I) to the
off position (0).
If a second occurrence of one of the above actions occurs within the time-out period, the timer will be reset and the delay
period will start again.
The time-out delay is deactivated when the CJB receives one of the following signals:
The CJB receives a lock signal from the remote handset
Ignition switch is moved from the off position (0) or the auxiliary position (I) to the ignition position (II) or the crank
position (III).
The CJB receives a door opened signal (even if door is subsequently closed)
Interior Lamp Time-out Personalisation
The vehicles customer personalisation options allow the driver or a Land Rover or authorised dealer to adjust the interior
lamp switch-off delay period to suit their specific requirements. The default delay period of 60 seconds can be adjusted to
the following values; OFF, 10 seconds, 20 seconds, 40 seconds, 60 seconds, 120 seconds or 240 seconds.
With the vehicle stationary and the ignition switch in nay position, pressing the trip computer button on the end of the left
hand steering multifunction switch gives access to the Customer Personalisation options. Using the audio search buttons
on the steering wheel the options can be scrolled through. The options are displayed in the message center. When the
headlamp delay option is reached the settings can be changed using the audio search buttons on the steering wheel.
When the selection has been made, confirmation is performed by pressing the trip computer button. For additional
information, refer to

Battery Saver
The battery saver feature provides automatic shut-off of the interior lamps after a period of 15 minutes in order to prevent
excessive drain on the battery. The lamp(s) fade off as described in the 'Interior Lighting' section that follows.
The battery saver feature is additional to the time-out delay feature and prevents battery drain when an lamp is
accidentally left switched on, e.g. glove compartment left open.
