Red face Lane departure warning and ASL for XJ

Hi guys,

First, my XJ is 2017MY. (X351)

I installed new rear-view mirror and it has a mono-camera. I think this mono-camera is called HCMB. (maybe?) It's because I found that HCMB and IPMA are different from the as-built. On SDD it looked like IPMA.



AHBA and TSR work fine. No errors.



In the case of Range Rover, I found that Intelligent Speed Limiter and LDW (Lane Departure Warning) can be used when the same HCMB is installed. The only difference is that they have physics buttons. I was giving up because I couldn't find the LDW button on XJ's parts list. This is because even if the CCF is modified, none of the LDW related menus are displayed on the Instrument cluster.

- Adding forward collision warning and lane departure? | Page 2 | Range Rovers Forum

The only case of XJ is LKA. If I change LKA value to "Fitted" in CCF, a lane appears on the cluster. But it doesn't work with error and no setting menu.


Adaptive Speed Limiter(Intelligent Speed Limiter) is little bit different. No errors, but no menus available, either.

However!!!!! I found positive examples at F-Pace. F-Pace had a menu to turn on/off LDW and ASL in Cluster. There is very little hope.

I am trying to find a workaround. Does anyone have any good ideas?

Many thanks,
KIM

Hello Kim,
First, let me ask a couple of questions:
Which version of SDD are you using?
From which file(s) are your code snippets?

Since you are a programmer, you may know:
CCF is/are configuration file(s). JLR service/training literature alternately refers to Car Configuration File or Central Configuration File.
The files are continuously broadcast on both HS and MS CAN buses.
Typically, one bit of an eight-byte CCF message line will adapt the internal program of a particular control module.
Two or more control modules may require activation of a feature for it to be fully activated.
That would require "enable" bits on different CCF messages.
Example: the CCF posted by KurtC shows two different locations enabled to complete the "rear parking camera" enable for the XK/XKR.

Also, the feature that you would like to enable may require module programming if a new/different control module is introduced to the vehicle.
Since you indicate a different module name, that would seem to be the case.

The code snippets that you provide address "qualifiers". Qualifiers are used by SDD to selectively allow model specific programming of modules that are options provided by the OEM.
Optional modules are shown using a square box in SDD diagnostics.
Where features are not qualified, it may be possible to edit SDD to allow the required module to be programmed. However, that may not be sufficient to activate the feature:
if existing modules are required to support the feature but have not been OEM programmed to do so, simply enabling CCF will accomplish nothing.

Example: the 2008+ XF has blind spot monitor as an option that may be added. The XF and XK are VERY closely related. Adding BSM to the XK has, thus far, been elusive in spite of SDD program edits to qualify XK BSM. However, it is still a work in progress.

Bill
