Open to any guidance. I reset to previous condition and started over. Based on Hairy Dan's sticky post, I enabled these 3. the buttons on the right hand side of the steering wheel light up. Nothing else happens. The button on the left hand side does not light up. Are there additional procedures necessary to get it to work? Calibrating cruise ecu, or something like that?

I’ve had a couple activations still not work after a couple Pivi resets, but then start working in the next day or two. Configurable Terrain Response was one. Enabled with a G4, nada. Pivi reset nada. Repeat, nada. Next day, works.

Here's what I did on mine last week.
This is a copy/paste from someone else's work that I followed along with. Once it was done I had to manually clear the DADC errors by going into the faults tab and clearing them after leaving the car sit for an hour locked with the alarm set. As far as operations... I do wonder if you did activate it, but aren't using it right? Once you see the two arrow buttons enabled on the right side of the wheel you should be ready to go. Get onto a motorway and set the cruise for slightly higher than the car in front of you. Now select the short arrow button to draw down the distance between the two of you. You should get a graphic on the dash that shows some big green blocks that you add and subtract with the short and long arrow buttons. That's it.. it's on. When you are locked onto the car in front of you, you will see a green indicator light on the dash that is different than the "cruise on" indicator. There are no buttons related to the cruise or ACC on the left side of the steering wheel. Give these files a look and let us know how it goes. Don't give up yet, you're close! Start here... Activate ACC Auto Cruise Control 1,2,3,4 first, then any optional ones if it doesn’t work 1 EUCD-023 Cruise Control Standard: Without cruise control Changed to: Adaptive Cruise Control Stop & Go 2 MultiCAN-580 PTCruiseFitment Standard: Normal cruise fitted Changed to: ACC with Queue Assist fitted 3 MultiCAN-809 ACC Stop Gap Setting Standard: Not fitted Change to: Fitted 4 MultiCAN-712 ACC Lead Car Dist Disp Standard: Fitted Changed to: Fitted * this was already set on my car ____________________________________________________________________ I also set these parameters, cause I read about it somewhere. But what does this really it do? MultiCAN-753 Adaptive Prog Mode Standard: Not fitted Changed to: Fitted And I found other settings, which are listed as unsupported, but sounded interesting to ACC. Perhaps some defaults to set in the PIVI – but did not find anything yet ?MultiCAN-712 MultiCAN-712 ACC Stop Gap Select ?Standard: Not supported ?Changed to: Fitted ?MultiCAN-712 ACC Accel Profile Select ?Standard: Not supported ?Changed to: Fitted Optional?

I had the exact same issue but after updating the firmware on the G4 two days ago I did the same thing again and it worked.

Thanks. i've given up for the moment trying to get it to work/engage. I'm sure as more folks do it we'll see more guidance or specifics on any process nuance. 2020 SE First Edition

Quick update to close this out. Updated to latest build (as of Monday), build 98 from build 80 and tried again. It now reflects a lot more steps in resetting ecu’s, etc (these may have been happening before but there was no visual feedback, now there is). Now the functions work as expected for the most part.
Now that I have it activated fully, ACC works great for me. There is none of the surging and abruptness that some have reported and it’s pretty smooth on my regular 100mile trip. 2020 SE First Edition 2004 Disco2 1986 110 V8 1971 Series IIa 88” |
