Trying to use a pair of adaptive headlights in my non adaptive 2008 xk.
Bill400 told me I could enable the adaptive function with sdd but I would still need the other modules, etc.

I am not concerned with incorporating the adaptive ability, only want to be able to use the headlights. A quick glance confirmed that the pin in/out configuration is different.

Does anyone know where I might find a diagram showing the pin locations or each different unit?

Thanks

Sorry, I was looking at 2010. 2008 may use different designations for the connectors.
The connector designations for the XKR are different for the same connector which adds confusion.
Consider paper copies to markup, side by side.

Additional CHARM pages will be required as you proceed.

 

thank you Bill400,

trying to decipher everything...I cannot find a wire chart for the adaptive headlights, do they both use the same wiring layout and through multiplexing the signals are being sent to the l-r motor?

@wymjym

Gus Glikas' Jagrepair.com has the best electrical manual. I have printed pages on 11 x 17 (native size) for side-by-side use and readability. OfficeMax, Office Depot, etc. can print that from a USB drive.

Free Service Manuals for 2008 Jaguar vehicles | Operation CHARM is another source. XK and XKR (non-AFS & AFS) electrical manuals are shown separately but are the same.

Under the heading "Locations", Charm shows the connectors with images and pinouts.

The non-AFS and AFS systems are shown on adjacent pages of the electrical manuals. If you use JagRepair and Charm intermittently (as I do), be sure that the connector designations are the same before referring to the Locations/Pinouts. My preference for paper has caused confusion on occasion.
Note also that the connector designations (for the same connector) may change between the adjacent non-AFS and AFS pages! (Not a problem when I checked FL030 and FR008)
So, review/compare connector designations on different wiring diagram/plans before referring to the Location/pinout.

When faced with a then new to me XK with one non-ASF and one ASF, I took the easy way out and sourced a non-ASF.
Prior to that, the ASF headlight worked without wiring modification. But side marker and cornering light did not work.

If I had two ASF that I believed in working condition, I would have sourced the ASF control module, edited wiring thus converting to ASF, then edited CCF to have an upgraded lighting system.
The steering sensor is existing/present (for DSC), and no other modifications should be required to upgrade the headlight system.

PS: Headlight pins 8, 10 and 12 and supply from CJB are common to non-AFS and AFS. However, the elevation motor control is different.
If the residual headlight position is within the range of manual adjustment, it appears that the AFS could work in place of the non-AFS without modification. But not recommended as a permanent solution.

Keep us posted on your progress.

 

So much info! Thanks.
After studying the schematics plus your explanation @ editing I've decided to take a more rudimentary approach. I don't have the editing equipment but two original hl assemblies (still installed and working-but with damaged adjustment mechanisms) and two like new afs assemblies in a box.
When I have time I'll pull the installed units, compare the internal wiring of both types, make appropriate physical changes and install the 'modified' afs ones.
thanks again for your time!

You can install the AFS in place of the non-AFS, as-is, and they will work (light).
If the internal motors stop close enough for the manual adjustments to acheive alignment, you are done (but without motor operation/adjustment).

If you were to successfully rewire the HL internals to control the non-ASF (up and down) motor, you still have the inoperable horizontal tracking motor (potential problem).
The internal modification of AFS to non-AFS would be quite (very) difficult and would be incomplete, as mentioned.

If you want to use the nice AFS headlights, source an AFS controller (with socket), edit the wiring to the controller and HL sockets and then edit CCF.
That will be much easier than modifying HL internals.

Or you might consider swapping the AFS for non-ASF.

PS: There is likely someone nearby with SDD or there is another way.

 

I assumed that if I removed the l- r mechanism, mimicked the non afs wiring I would be good to go.
Then I found an explanation of everything the afs does and all the inputs. My assumption was wrong!
I'll post the info I found later in this thread, it is quite interesting.

AFS data from the workshop manual.

ADAPTIVE FRONT LIGHTING SYSTEM (AFS)

The AFS headlamp is similar in its construction to the Xenon, non-AFS headlamp. The projector

module is constructed and functions as described for the Xenon headlamp but with the addition of

the AFS system which allows the projector module to be moved vertically and horizontally. The AFS

system is controlled by a AFS control module which is integral with the headlamp levelling module.

The AFS headlamp assembly contains an additional carrier frame which provides location for the AFS

actuators. The remaining lamps are as described previously. The carrier frame is attached to the AFS

vertical actuator. The projector module has a central pivot point which allows the module to move

horizontally in response to operation of the AFS horizontal actuator.

The AFS actuators are bi-polar (2 phase) dc stepper motors which are driven by a power output from

the AFS power module located on the rear of the headlamp assembly. Each stepper motor receives

its position information from the AFS control module via the applicable AFS power module. When

the actuators are powered to their requested positions, a holding current is applied to maintain the

actuator position.

The actuators do not supply a positional feedback signal to the AFS control module. Each stepper

motor requires referencing each time the AFS system becomes active. When the AFS system is

active, each vertical actuator is driven to the low beam position and each horizontal actuator is

driven to an inboard position until a mechanical stop in the actuator is reached. Once the stop is

reached a step counter in the AFS control module is set to zero and the actuator is then powered to

the operating position as determined by the AFS control module software.

The AFS control module receives front and rear vehicle height data from the height sensors to

provide headlamp levelling adjustment via the vertical actuator motor. The AFS control module also

receives vehicle speed signals from the ABS module to adjust the projector module vertically to

increase the beam range as the vehicle speed increases. (wow)

AFS Control Module

The AFS control module is located on the bulkhead, at the bottom of the RH (right-hand) 'A' pillar.

The AFS control module is a dual functionality unit which also incorporates software to control the

headlamp leveling. The AFS control module is connected to the high speed CAN (controller area

network) bus and receives inputs from other vehicle systems on the status of the following parameters:

• Steering angle

• Vehicle speed

• Headlamp status

• Engine running

• Reverse gear selected

• AUTO lights on.

The AFS will only operate when the AFS control module receives an engine running signal on the high

speed CAN (controller area network) bus from the ECM (engine control module) . When the engine

running signal is received the AFS control module performs its initialisation routine.

The AFS will also function when the lighting control switch is in the AUTO position and the AFS

control module receives a lights on signal from the light sensor and an engine running signal.

The AFS control module then monitors the inputs from the other vehicle systems to control the AFS

functionality according to cornering angles and vehicle speed.

The AFS control module is connected to each AFS power module on a private Local Interconnect

Network (LIN) bus. The power modules read operating values supplied from the AFS control module

and control the output drivers for the stepper motor actuators inside the headlamp assembly.

The AFS controls the swiveling angle of each projector module using speed and steering angle signals.

The angles of each projector module differ to give the correct spread of light, for example, when

turning left, the LH (left-hand) projector module will have a greater swiveling angle than the RH

(right-hand) projector module.

Initialisation Procedure

When the AFS control module receives an ignition mode on signal, the control module performs the

initialisation procedure which ensures that the headlamps are correctly aligned on both their vertical

and horizontal axes.

The headlamp leveling motors are powered from their current position, which can be either the

upper or lower limit or somewhere in between, to their lower position and then back to the 0

degrees position.

The AFS swivel initialisation starts less than 1 second after the headlamp leveling initialisation is

activated to ensure that the headlamps are at or below the 0 degree position in the vertical axis, thus

preventing glare to oncoming vehicles. The AFS swivel initialisation is completed in less than 2.5

seconds. The LH (left-hand) and RH (right-hand) AFS actuator motors are powered from the 0 degree

position to their fully inboard position, then to their fully outboard position and then back to the 0

degree position.

Failure Mode

In the event of a failure of the AFS system, a warning indicator in the instrument cluster is illuminated

to warn the driver. The AFS warning indicator illuminates when the ignition is in the ignition on mode

and will flash continuously until the fault is rectified. The AFS warning indicator will also be

illuminated if a failure of the steering angle sensor or the vehicle speed signal is detected.

Illumination of the warning indicator does not necessarily mean that there is a fault with the AFS

system. The fault may be caused by a failure of another system preventing the AFS system from

operating correctly.

The AFS control module performs a diagnostic routine every time AFS is requested. If any fault is

found, the AFS control module will suspend the operation of the AFS function.

If the AFS leveling system has failed with the projector module in a position other than the correct

straight ahead position, the AFS control module will attempt to drive the projector module to a

position a small amount lower than the standard position. If the swivel function has failed, the AFS

control module will lower the projector module using the leveling actuator to a position much lower

than standard to prevent excess glare to oncoming vehicles.

The AFS control module software can detect an internal failure of the control module control circuits.

The control module will power the projector modules to the zero position and prevent further

operation.

Faults can be investigated by interrogating the AFS control module using an approved Jaguar

diagnostic system to check for fault codes.
