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.

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.

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.


Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.

1. Verify the customer concern

2. Visually inspect for obvious signs of damage and system integrity



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
