Description and Operation

The headlamp switch is located on the driver side of the instrument panel. It also operates the sidelamps, fog lamps, "Auto Mode",
headlamp levelling and the trip switch.

Each headlamp assembly consists of two lamps. The side lamp and the high beam lamp are the inner and the low beam and turn signal
lamp are the outer. Access for bulb replacement is from the engine compartment.

High intensity discharge (HID) lighting is fitted as an option.

WARNING: Voltages of up to 25 KV are possible with HID lighting.

Burner wear for HID lamps is so low that the burner lasts the lifetime of the vehicle under normal use. The HID bulbs are dealer replaceable
only.

• NOTE: After replacement of a sensor or module the HID lamps will need to be calibrated using a Jaguar Approved Diagnostic System.

The front fog lamps are located in recesses in the front bumper. The two retaining screws are located behind the splitter vane and are
accessible after removing the radiator splash shield.

The license plate lamp bulbs on all vehicles can be accessed by releasing the retaining tangs on the side of the lamps.

Each rear lamp assembly incorporates a stop/tail lamp, a fog lamp, a reversing lamp and a turn signal lamp. Access for bulb replacement is
from the luggage compartment.

The high mounted stop lamps for both 4-door vehicles and wagon are replaceable as units. On 4-door vehicles, the two retaining screws are
located behind the headliner and are accessible after the headliner has been removed. On wagon, the three retaining screws are located
below the tailgate spoiler, and are accessible after the tailgate spoiler has been removed.

On vehicles up to 2009MY, the side repeater lamps are located in the front fender. On vehicles from 2009MY, the side repeater lamps are
located in the door mirrors.

The side marker lamps on 4-door vehicles are located in the front bumper and rear bumper cover. These are located in each bumper cover by
tangs on one side of the unit and held in position by a spring clip on the other side. The rear side marker lamps on wagon are incorporated
in to each rear lamp assembly.

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, verify the symptom and refer to the Jaguar Approved Diagnostic System.

DTC Index

WARNING: Voltages of up to 25 KV are possible with HID lighting

• CAUTIONS:

Observe all recommended safety precautions relating to the operation and repair of headlamp systems. Refer to health and safety

guidance in the owner guide and repair manual for further details.

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

• NOTE: If the control module/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 program is in operation, prior to the installation of a new
module/component.

• NOTE: 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.

• NOTE: Check and rectify basic faults before beginning diagnostic routines that involve pinpoint tests.

• NOTE: Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.

• NOTE: 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.
