Facelift 3.6 TDV8 - Coding Out Cruise Radar Sensor

Was hoping to get a definitive answer/guidance/advice as despite my best effort and searching I cannot find a solid answer.

I’m getting an intermittent “forward alert not available” message on my L322. Happens at random with no real pattern - can be driving 10 mins or 1 hours, or sometimes doesn’t happen at all. GAP IID tool suggests faulty radar sensor and my local specialist has also confirmed this too.

It’s a real pain as it disables to cruise and generally speaking, my L322 is only really used for long journeys towing my track car and covered trailer.

So the question is, on a facelift L322 with the 3.6, can the radar sensor be coded out? So the cruise would just work like normal cruise?

The internet suggests it can be done with the GAP IID tool on the facelifts but the posts I’ve found never say if it’s a 3.6 or a 4.4 TDV8. The reason I ask is that according to some parts diagrams on classic Land Rover, it seems the radar sensors differ on the facelift 3.6 and 4.4. One diagram suggests the 3.6 had an extra radar sensor.

If the answer is yes - how can it be done in the GAP tool? Secondly, is this regarded as a bit of a bodge? As opposed to shelling out the £2k for a new sensor?

For reference my car is:
2010 L322 facelift Vogue SE
3.6 TDV8
ZF6 Box
Digi Dash etc
Cats/No DPF

Thanks in advance!

I've reverted to standard CC on my MY12 because the sensor failed, after having retro-fitted ACC some years earlier. There are several parameters to change but also the fuse to the radar sensor has to be removed to prevent unexpected messages from the sensor on the HS canbus.

The 4.4's ECM handles CC/ACC but the 3.6 uses an older ECM which might use a separate module for ACC, in which case either unplug the module or remove its fuse if the fuse is solely for the ACC module. Some diagrams show an ACC module near the rear fuse panel. Some diagams show a 2nd radar sensor connected to the main sensor for the 5.0 and the rear ACC control module too. However people have retrofitted to 5.0s with only 1 radar unit and no ACC module so the 5.0 information is at least sometimes incorrect.

Thanks Graeme. A lot of the searching I've done has your input on the threads.

Does the digi dash work ok when you disable the ACC element? It all seems well integrated so was worried about gremlins popping up if I removed. Standard CC would be ideal for how I use the car so I think I'm going to go down the route of just disabling the ACC.

Do you know which options I need to change in the GAP tool to remove it? Again, I'd seen on a thread about needing "full CCF access" - is this required to remove? Do you have any resources to track down the correct module/fuses to unplug/remove please?

Obviously if there is anyone who has done this specifically on a facelift 3.6 - please let me know.

My wiring diagrams don't include the 3.6 engine, possibly because I didn't download it from Topix, but I don't see a separate ACC module on the HS canbus diagram indicating that MY10-12 don't have that module.

Mine's radar sensor fuse is #17 in the engine bay auxilliary fuse box.

When I get a chance I'll connect my IIDtool to see if I can spot the parameters that I reset.

These 2 pictures show the parameters that I altered to enable ACC which would need to be changed to standard CC.

Brilliant thank you! I'll plug in my IID tool and see what options I have. In the meantime, could you advise which wiring diagram from Topix you'd suggest I download for my 3.6? I've uploaded a screenshot of whats available for my car.





Would changing those parameters in IID also totally remove all the forward alert options in the vehicle menus too?

The 3rd one, the EWD.

I don't recall if the foward alert option still shows but it's of no consequence if it does but I expect it would show Not Available.

Thanks again Graeme.

I'll dive into the engine bay fuse box and see how it differs from what you've got on the 4.4. Hopefully its the same, I can switch the CCF options in IID and it works from there.

I'll report back!

also trying to solve this

What I have noticed is that Kia and Hyundai vehicles with more of the self-driving technology in them causes my forward alert to go off / disable itself which disables the cruise control. These vehicles are so prevalent now that I can't drive 10 miles without it happening. I want to just go back to regular cruise control, never cared for the adaptive part. I have set the JAG Cruise Control to Normal from ACC and Cruise Control to Fitted and Cruise Control Speed Display to Standard speed control full display plus priority messages. However, when I turn the vehicle on now it immediately give a Forward Alert not available message...hence causing it to disable the cruise control. I've tried pulling Fuse 17 under the hood, no change in effect. If I remove that fuse 17 before configuring the settings in IID Tool it also immediately posts a Forward Alert Not Available message. I've also removed fuse 6 in the passenger compartment which is for ACC and tried combinations of only Fuse 6, Fuse 6 and Fuse 17 removed. I immediately always receive a Forward Alert error which disables the cruise control.

These are the settings I have for body control.

Has forward alert in the CCF been disabled?
Edit: There migh tnot be a CCF setting - I'll check what I changed to revert to std CC.

Is Forward Alert still enabled in the configuration menu?

I don't see anything related to Forward Alert in the CCF.

Forward collision warning is my IIDtool's parameter.

Edit: My IIDtool doesn't sort parameters by description (no CCF parameter number shown either) and Forward collision warning is the last parameter on my special ACC CCF list. Maybe Gap have changed the parameter description in a later version so you will need to check all parameters looking for a similar description.

7 parameters for ACC and 2 for Stop and Go, noting that Stop and go wasn't factory-enabled on the L322.

Thank you GraemeS, i've read all of your posts on here and always noticed your settings available via IID Tool were different than mine. I'll reach out to Gap Diagnostic and see if there is a setting not available on mine that needs to be exposed to disable this.

I am surprised not to see more posts from ppl getting interference from Kia and Hyundia driver assistance technologies. Thats what spurred all of this. I'm also considering a recalibration of the sensor (via IID Tool) to see if that resolves the issue as I think I would see more people reporting this issue if it was a broader issue with the radar unit.

I have turned mine off now, as I hate the adaptive cruise control. Why not give us a choice, Land Rover?

Anyway, I had to mess with some CCFs that are not in the standard list, so you have to ask GAP to give you the full list.

I get an error saying Forward Alert is not available, so there's still something I need to tweak, but normal cruise is working perfect! Thumbs Up
