JUNCTION BOXES

Inputs System Operation
The CJB receives the following inputs which affect the operation of the interior lamps: Ignition mode
Lock/unlock
Luggage compartment lid latch switch
Door latch switches.
Outputs
The RJB outputs the following for the interior lighting system: Luggage compartment lamp power supply
Driver and passenger door module power supplies
Fade on and off grounds for front and rear overhead console interior lamps and footwell lamps
PWM (pulse width modulation) power output for the ambience lighting.
Interior Lamp Time-Out

The interior lamps are controlled by a timer within the CJB which allows a 60 second delay period for the lamps to remain active after the ignition mode has been changed to off power mode 0 or the vehicle has been unlocked. The interior lamp fade
off is controlled by the RJBvia a delayed power off relay in the CJB. The following interior lamps are subject to the delay period:

Front overhead console interior lamp
Rear interior lamps
Footwell lamps
Door mirror approach lamps.
The timer delay is activated when the CJB receives one of the following signals: An unlock signal from the Smart Key via the keyless vehicle module.
Ignition mode is changed from the crank power mode 9 or ignition power mode 6 to the accessory power mode 4 to the
off power mode 0.

If a second occurrence of the above actions occurs within the timer period, the timer will be rest and the delay period timer will
restart.
The timer delay is deactivated when the CJB receives one of the following signals: A lock signal from the Smart Key via the keyless vehicle module
Ignition mode is changed from the off power mode 0 to the accessory power mode 4 or ignition power mode 6
The CJB receives a door opened signal (even if that door is subsequently closed). Battery Saver

The battery saver provides an automatic shut-off of the interior lamps after a period of 15 minutes in order to prevent
excessive power drain on the battery.

When the ignition mode is changed from the ignition power mode 6 or accessory power mode 4 to the off power mode 0, the
CJB starts a timer which de-energizes a delayed power off relay in the CJB, removing the power supply to the interior lamps after a period of 15 minutes, switching off all or any interior lamps which have remained on for any reason.

1 LH map reading lamp bulb 2 Interior lamp bulb 3 RH map reading lamp bulb 4 Printed Circuit Board (PCB) - JaguarSense 5 Ambience lighting LED's 6 RH map reading lamp 7 Interior lamp 8 LH map reading lamp The overhead console is located near the windshield in the head lining. The console can be removed by carefully levering out
the rear edge of the housing to release 2 spring clips, and then pulling the console rearwards to release 2 locating tabs.
Removal of the console is required to replace any of the interior or map reading lamp bulbs.

The interior lamps and air bag off warning lamp in the front overhead console are common to all vehicles. The overhead
console can also contain security system intrusion detection module and volumetric sensors, sunroof switch and a voice
activation microphone depending on vehicle specification and market.

The interior lamp can operated manually using the JaguarSense feature to switch the lamp on and off. The lamp is also
controlled as part of the automatic interior lighting system.
The map reading lamps only operate manually using the JaguarSense feature to activate the lamps.

The interior and map reading lamp bulbs are located in holders which locate in a PCB. The PCB also provides for the operation
of the ambience lighting LED's, the air bag off warning lamp and the JaguarSense proximity sensors which are integral with the PCB.

The overhead console also contains 2 LED's for the ambience lighting system. The ambience lighting is part of the lighting control switch functionality and is subject to the setting of the instrument panel illumination dimmer control in the auxiliary
lighting switch. The ambience lighting provides very limited illumination of the instrument panel and floor console when the
vehicle is being driven without affecting the driver's visibility. www.JagDocs.com

DTC Description Possible Cause Action U300362 Battery Voltage

of 2 volts or more, between
CJB and RJB Carry out any pinpoint tests associated with this DTC
using the manufacturer approved diagnostic system. Rear Junction Box (RJB)

CAUTIONS:


Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee
confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle


When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number
3548-1358-00
NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
warranty policy and procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to
the installation of a new module/component


Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system)


When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places and with a
current calibration certificate. When testing resistance, always take the resistance of the digital multimeter leads into account


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion


If diagnostic trouble codes are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent
concern may be the cause. Always check for loose connections and corroded terminals


Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the
manufacturers approved diagnostic system


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required
