The radar fuse can be removed at any time but a restart is required before standard CC will work.
Yes, select the non-ACC option on those parameters, such as 'standard speed control' or simply 'speed control'. 1 or more parameters have multiple ACC options so best to note them before changing in case you want to re-activate ACC. Other CCF parameters exist that are only used if ACC is fitted/enabled so those should be left untouched.

Well a 400 mile round trip today gave me plenty of time to try all combinations of CC switches. Nothing I did turned the dreaded "adaptive" off. Double clicking the set switch just increases the speed by an MPH or two. Multiple clicking increases the effect. Holding no different. Minus does the opposite as you'd expect. Holding the distance buttons full in, full out or both together doesn't do it. I'm guessing that if there is a method it will be one of those weird ones (like the old phone paring methodology) which has to be described in a 17 point tech bulletin as its so counter intuitive.

I'll fire up the IID tool next week and see if I can beat the system that way.... Mike - MPx

I assume that your vehicle doesn't have ACC otherwise you would have tried disabling it. Mine's ecm is down at least 2 update levels on what's currently available so there's a remote chance that the very latest L322 s/w might have the feature.

Thanks Stan!
Adaptive CC can be totally disabled by removing the fuse for the radar unit then changing several CCF parameters using your IIDtool, having only recently retro-fitted ACC to my MY12 TDV8. However Stan's suggestion would be preferable although ACC might be restored on next start-up. I'm going to try Stan's suggestion as sometimes I would prefer mine's original, standard CC.

Was the radar unit bumped during the grille change? Maybe the radar unit needs to be recalibrated for the new grille, which could be an IIDtool function if the function exists for your vehicle.

As far as I know the radar unit was not bumped during the grille change. I tried the calibration today and even during the calibration it says radar is blocked so I have a feeling it won't calibrate.

I guess my next steps is to try and disable through the IID tool with CCF functionality and not take out the fuse. Hoping I can still disable it while leaving the radar connected with fuse on.

If that doesn't work I'll try to disconnect the radar sensor, and leave the fuse on because I don't want the ACE system to stop working I need the active sway bars.

Okay I was able to disable the radar / adaptive cruise control / emergency braking with the IID tool on my 2015 Range Rover Sport L494 autobiography.

I was getting some parking brake errors during the process, it turns out I just needed the right set of settings, so here are all of the settings I used. I did not need to remove any fuses for this to work. I only had to do this because I had an aftermarket front bumper that blocked the grille, and I never liked that adaptive cruise control feature / emergency braking.

Adaptive speed control ECU - Unchanged - North America, Canada, Mexico, Australia
Adaptive speed control ECU - Unchanged - Standard blockage level -40dB
Adaptive speed control ECU - Unchanged - Follow mode off
Standard speed control display type - Changed - No speed control display
Adaptive cruise control indiction in instrument cluster - Changed - Disabled
Speed control - Unchanged - Adaptive speed control, stop and go (this was required to get the parking brake fault to go away)
Intelligent cruise control - Changed - Not fitted
Speed control - Changed - No speed control is fitted
Speed control - Changed - Speed control not fitted
Low speed intelligent emergency braking - Unchanged - Not fitted
Low speed intelligent emergency braking - Unchanged - Not fitted
Collision mitigation by braking - Changed - Not fitted
Collision mitigation by braking - Changed - Without collision mitigation by braking

For members over this side of the pond, be careful not to copy the above otherwise your car might want to drive on tuther side of the road

Australia is RHD and I haven't noticed my RR preferring the other side.

Mine works fine and I like it, the adaptive bit stops me running into the back of someone when I fall asleep  Geoff

that's a bummer, i'm sure i read that procedure worked...

That’s interesting that you can’t get in with it, I’ve come from normal cc to the acc and I love it, I found that you have to read the road ahead a bit so I anticipate the car in front slowing and move out before the system detects the slower car to maintain my set speed then move back in when I can, sometimes I can’t move out as the next lane is travelling faster then the speed I’ve set so I just sit behind and wait until a gap opens then move out.
