2010 JAGUAR XFR fuses

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 is received by the CJB from one of the following:
Ignition mode changed from off power mode 0 to accessory power mode 4, ignition power mode 6 or crank power mode
9.
Any door, including the luggage compartment lid is opened
An unlock request is received from the Smart Key via the keyless vehicle module
Overhead console interior lamp is switched on via the JaguarSense function.

INTERIOR LAMPS

When the interior lighting system switches the interior lamps on, the CJB ramps the lamps up to full power over a period of 1.3 seconds. When the system switches the lamps off, after the time-out period has expired, the CJB 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 CJB receives an unlock signal from the Smart Key via the keyless vehicle module Any door is opened including the luggage compartment lid
The ignition mode is changed from ignition power mode 6 or accessory power mode 4 to off power mode 0.
The interior lighting system will turn off the interior lamps when one of the following events occurs:

Once the time-out timer delay has expired since the lamps were either activated or the last door is closed and the
vehicle is not locked
The ignition is in off power mode 0 and an external lock is requested (using either the door lock buttons or the Smart
Key) with all doors closed
The ignition mode is changed from the off power mode 0 or the accessory power mode 4 to the ignition power mode 6
The last door is closed and the vehicle is externally locked, on receipt of an unlock request from the Smart Key or door
handle operation detected when the time-out timer is still active.

DELIVERY MODE

Delivery mode is set at the factory on vehicles to minimize battery drain. The mode enables the switching off of non-critical
electrical components, including the interior lighting system. The delivery mode feature is cancelled by the dealer during the
Pre-Delivery Inspection using an approved Jaguar diagnostic system.

CRASH ILLUMINATION

When a crash signal is received from the RCM (restraints control module), the CJB activates the interior lamps once the vehicle speed has reduced to 5 km/h (3.1 mph). The hazard flashers are also activated and the doors are prevented from being locked.
The lamps remain on until the crash signal is removed, they cannot be switched off using the JaguarSense feature. The crash
signal is removed by completing one ignition on and off cycle.



INTERIOR BULB TYPE/RATING Component Description

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


NOTE: The front overhead console and the front door ambience lighting is illuminated by LED's and are non-serviceable components.

The CJB is an integrated unit located on the RH 'A' pillar, below the instrument panel. The CJB contains fuses, relays and number of microprocessors which control the power supply and functionality of the interior lighting system and other vehicle
systems.

The RJB is located on the RH side of the luggage compartment. The RJB contains fuses, relays and microprocessors which in conjunction with the CJB control the interior lighting system and other vehicle systems. Circuit Protection

The CJB and the RJB provide circuit protection for all interior lamp circuits. The lamps are protected by fuses in the CJB and the RJB.

Inspection and Verification


CAUTION: 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.
1. Verify the customer concern.
2. Visually inspect for obvious signs of damage and system integrity.

Visual Inspection
Mechanical Electrical
Bulbs
Fuses/relays (refer to electrical guide)
Wiring harness
Correct engagement of electrical connectors
Loose or corroded connections
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

DTC Index


CAUTION: 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 five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give extra information read by
the manufacturer-approved diagnostic system).


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


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


If DTCs 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.

CAN harness loops into the module (via two connector pins) and then loops out of the module (via another two connector
pins). In the 'spur' type configuration, a harness spur is spliced into the main 'backbone' of the CAN harness and the module is
connected to the harness spur via two connector pins. Electrical

If DTCs 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


The DTC index containing an actions list is for guidance only any reference to “check and install new blower unit” should
only be carried out following failure confirmation using the pin out diagnostics and/or the over temperature and fluid/air leak
diagnostics contained below. The recording of a DTC does NOT signify a permanently failed unit


The climate system functions in a manner that means any detected error state either intermittent or permanent will shut
down the complete seat climate system until the next ignition cycle, this does not mean that both climate units within the one
seat have failed. This shut down is design intent to protect the system to ensure that the fault detected does not damage the
units, it is possible that both units are functioning correctly and that the fault lies elsewhere within the system. The following
process can be carried out without removing either the seats or the climate units from the vehicle and should correctly identify
any failed units, this should ensure that only failed units are changed under warranty. Any units exhibiting the correct reading
as per process below, should NOT be changed under warranty. If all units have a correct reading then re-confirm customer
symptom, if customer symptom is still present then carry out further system checks
