fog light bulb JAGUAR XF 2009 1.G Lighting In Detail Manual

When a crash signal is transmitted from the RCM (restraints control module), the RJB activates the hazard flashers. The hazard flashers continue to operate until the ignition is in the off
power mode 0 or accessory power mode 6. Once this ignition state has occurred, the RCM will cease to transmit the crash signal.
LIGHTING CONTROL SWITCH
The instrument cluster outputs 2 reference voltages to the rotary lighting control switch; one feed being supplied to the light selection function of the switch and the second feed being
supplied to the auto headlamp exit delay function. The switch position is determined by instrument cluster by the change in returned signal voltage which is routed through up to 4
resistors in series depending on the selection made.
OFF - When the lighting control switch is in the off position, the reference voltage flows through 1 of the resistors. The returned signal voltage is detected by the instrument cluster which
outputs a message on the medium speed CAN bus to the CJB that no lighting selection is made. The reference voltage to the auto headlamp exit delay switch is routed through 4 resistors
which is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that auto headlamp or exit delay has not been selected.
SIDE LAMPS - When the lighting control switch is in the side lamp position, the reference voltage flows through 2 of the resistors. The returned signal voltage is detected by the instrument
cluster which outputs a message on the medium speed CAN bus to the CJB to activate the side lamps. The reference voltage to the autolamp exit delay switch is routed through 4 resistors
which is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that auto headlamp or exit delay has not been selected.
HEADLAMPS - When the lighting control switch is in the headlamp position, the reference voltage flows through 3 of the resistors. The returned signal voltage is detected by the instrument
cluster which outputs a message on the medium speed CAN bus to the CJB to activate the headlamps. The reference voltage to the auto headlamp exit delay switch is routed through 4
resistors which is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that auto headlamp or exit delay has not been selected.
AUTOLAMPS - When the lighting control switch is in the auto headlamp position, the reference voltage flows through 4 of the resistors. The returned signal voltage is detected by the
instrument cluster which outputs a message on the medium speed CAN bus to the CJB to activate the autolamp function. The reference voltage to the autolamp exit delay switch is routed
through 4 resistors which is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that auto headlamp has been selected.
AUXILIARY LIGHTING SWITCH
Headlamp Leveling Rotary Thumbwheel (Halogen headlamps only)
A power supply is passed to the headlamp leveling thumbwheel from the ignition relay in the EJB. Depending on the position of the thumbwheel, the voltage passes through 1, 2 or 3
resistors connected in series. The voltage through the resistors is passed to the headlamp leveling motor controller in each headlamp. The received voltage is determined as a request for
the appropriate level position and the controller powers the headlamp level motors to the applicable position for each headlamp.
Rear Fog Lamp Switch
The instrument cluster supplies a reference voltage and return to the rear fog lamp switch. The fog lamp switch is a non-latching, momentary switch.
When the fog lamp switch is off the reference voltage is passed through a 1Kohm resistor. The voltage through the resistor is returned to the instrument cluster that determines that no
request for fog lamp operation has been made.
When the driver presses the fog lamp switch, the reference voltage is passed through a 330 ohm resistor. The change is return voltage is sensed by the instrument cluster which
determines fog lamp operation has been requested. The instrument cluster transmits a medium speed CAN bus signal to the RJB providing the lighting control switch is in the correct
position. The RJB reacts to the message and provides a power supply to the 3 LED (light emitting diode)'s in each rear fog lamp. A fog lamp warning lamp in the instrument cluster will also
be illuminated when the fog lamps are operating.
The RJB will only activate the rear fog lamps if the headlamps are selected on or are active with auto headlamp activation. When the headlamps are turned off the fog lamps are also
turned off. When the headlamps are next switched on, the fog lamps will not be activated until the driver requests fog lamp operation.
• NOTE: The fog lamps do operate when DRL (daytime running lamps) are active.
HEADLAMP LEVELING
Manual Headlamp Leveling - Halogen headlamps only
A power supply is passed to the headlamp leveling motor in each headlamp from the ignition relay in the EJB. When a signal voltage is received from the headlamp leveling rotary
thumbwheel, the headlamp leveling motor controller in each headlamp uses the power supply to operate the motors and move the headlamp to the requested position.
Static Dynamic Headlamp Leveling - Xenon headlamps only
The headlamp leveling module receives a power supply from the ignition relay in the EJB. The same power supply is also supplied to the headlamp leveling motor in each headlamp
assembly. The front and rear height sensors are connected to the headlamp leveling module and receive a power and ground from the module. Each sensor has a signal line to the
headlamp leveling module to return height information to the module. The module uses the height signals from the sensors to calculate the vehicle attitude and supplies a signal to each
motor to power the headlamp to the required position.

ItemDescription Headlamp leveling rotary thumbwheel (halogen headlamps only)
Instrument panel illumination dimmer thumbwheel
Luggage compartment lid release switch
Forward alert switch (if fitted)
Rear fog lamp switch
The auxiliary lighting switch is located in the instrument panel, adjacent to the steering column. The switch has a rear fog lamp switch and a rotary thumbwheel to adjust headlamp
leveling on vehicles with halogen headlamps. The auxiliary lighting switch also has a forward alert switch (if fitted) and a rotary thumbwheel for instrument panel illumination dimming.
The rear fog lamp switch is a non-latching switch which provides a momentary signal to the instrument cluster. The fog lamps can only be activated if the ignition is in power mode 6 and
the headlamp or auto headlamps are selected on. If the fog lamp switch is pressed when the fog lamps are operating, they will be switched off. If the lighting control switch is moved to
the side lamp or off position or if the auto headlamps turns off the headlamps the rear fog lamps will be extinguished. If the headlamps are subsequently turned on the rear fog lamp
operation will not be active and the rear fog lamp switch must be pressed to activate the lamps.
HEADLAMP ASSEMBLY
Two types of headlamp are available; xenon or halogen. The headlamp is secured in the front of the vehicle with three bolts; one outboard bolt is screwed into the front upper cross
member, one inboard bolt in the front upper body gusset and one bolt located at the rear of the headlamp assembly which locates in the front fender reinforcing panel. Bulb replacement
requires the removal of the 3 bolts and the headlamp assembly.
The rear of the headlamp has removable panels which allow access to the bulbs for replacement. A large cover can be rotated counter-clockwise for removal allows access the headlamp
low beam halogen or xenon D1S bulb. Another large removable cover can be rotated for removal to provide access to the high beam bulb, side lamp bulb and cornering/static bending
lamp bulb (if fitted).
The headlamps have 2 adjustment screws on the rear which allow for the manual setting of the vertical and horizontal alignment.
On NAS vehicles, the headlamp is regarded as 'Visual Optically Left' aiming. The adjustment screws must be turned equal amounts to maintain the correlation in the vertical axis only.
There is no horizontal adjustment. Refer to the Service Repair Procedures manual for headlamp alignment data and procedures.
Each headlamp has an integral 16 pin connector which provides inputs and outputs for the various functions of the headlamp assembly.

Rear Stop and Side Lamp
The turn signal indicator, side and stop lamps and reverse lamps are located in each outer rear lamp assembly. The side lamps and stop lamps use 24 LED's. The 24 LED's are illuminated
at a higher intensity than the side lamp when the stop lamp switch is operated by pressing the brake pedal. A side marker lamp is fitted to the outer rear lamp assembly and is fitted in all
markets. The side marker lamp also uses 4 LED's and are active at all times when the side lamps are selected on.
The stop lamps can also be activated by the adaptive speed control system. A signal from the adaptive speed control module is sent via the high speed CAN bus to the RJB which activates
the stop lamps until an off message is received.
Turn Signal Indicator
The turn signal indicator lamp uses a Phillips Hypervision glass filament bulb. The bulb is located in a holder which has contacts which mate with contacts on lamp body. The holder locates
in the lamp body and is rotated to lock.
If a bulb fails, the remaining turn signal indicator lamps continue to flash at the normal speed. The applicable turn signal indicator in the instrument cluster will flash at double speed to
indicate the bulb failure to the driver.
Reverse Lamp
The reverse lamp also uses a Phillips Hypervision glass filament bulb. The bulb is located in a holder which has contacts which mate with contacts on lamp body. The holder locates in the
lamp body and is rotated to lock.
The reverse lamps are activated on receipt of a reverse selected message sent on the medium speed CAN bus to the RJB.
Rear Fog Lamp
The rear fog lamps are located in separate units attached to the luggage compartment lid. The rear fog lamps each use 3 high intensity LED's. The fog lamp locates in a recess in the
luggage compartment lid has a seal to prevent the ingress of water into the luggage compartment. The lamp is secured in the recess with a metal securing clip. The rear fog lamp is
activated using a button located on the auxiliary lighting switch in the instrument panel.
LICENCE PLATE LAMPS
Two licence plate lamps are located in the luggage compartment lid trim finisher. One is located adjacent to the emergency luggage compartment lid release key barrel cover and the other is adjacent to the rear view camera (if fitted). The licence plate lamps are active at all times when the side lamps are operating. Each lamp can be removed from the finisher by inserting a
wide, flat screwdriver blade or similar tool in a slot between the lamp lens and the finisher and gently levering the lamp from the surround. The bulb is a push fit in a holder which in turn is a press fit in the lamp housing.
