Introducing Bluepilot! A Ford specific fork for Comma3X / OpenPilot

[Naveen]

Hello Everyone

My Comma 3X is restarting 2-3 times when i power on my truck in the morning. Temp outside have been hovering around 24-28 degrees, not sure if that might be causing this. It runs fines all through the day afterwards.

Trying to understand if Cold weather is causing this. I typically don't unplug it from the mount,.

Good Afternoon
I cant see it under "bluepilot" menu also.

The BluePilot menu has multiple pages. Change to the steering page using the tabs on the right side of the page.

My cruise control is hosed. I started getting occasional errors, such as: blind spot system fault; cross traffic system fault; pre-collision assist not available; adaptive cruise not available. I could clear these with a code scanner, and make long trips with these only showing up maybe once or twice in a 4=5 hour trip, but they became more and more prevalent, and while I can still clear them, now, as soon as I start the truck, there they ALL are. Needless to say, my Comma 3x tells me Cruise Fault: Restart the truck to engage.

I tried to put the truck into normal cruise mode and while this shows in the settings, if I try to activate cruise control, I'm told "ADAPTIVE cruise control is not available". I've tried turning off all of the various components that make up adaptive cruise, but this doesn't change anything.

Can anyone suggest what might be happening? Could this be that the cable has failed? Or the harness? Or the unit itself?

Are there steps I can take to try to troubleshoot what might be going on?

I am still under a Ford extended warranty, but am concerned that if it turns out to be the car's modules that have failed, that this might be denied due to use of the Comma....can they tell if the Comma might be behind this?

Once you remove the comma harness they cannot tell the comma was ever there, so your warranty is good. This is most likely caused by the harness going bad or the USB-C cable going bad.

Step1: Unplug the USB-C cable from the harness box under the dash, if all the errors go away, the USB-C cable is bad, get a new one (remmember only very specific spec cables actually work).

Step2: If unplugging the USB-C doesn't make the errors go away, remove the harness from the IPMA and put the system back to stock. This should clear any issues.

Sorry for not getting back to this before you posted. I went out to swap out USB cables thinking this would be the easiest thing to check first (i.e. just going straight to the Comma from the harness (leaving the original in place in the event it wasn't the problem). In trying to get to the cable underneath, I must have tugged on the harness connection to the piece it replaced in the IPMA module and the 2 pieces just separated. I guess I never quite put them together well enough and over time, they must have gradually separated just enough to start creating problems, until they were just way too much separated to work at all. So, got a good solid click and took the truck out for a spin and it hasn't worked this well for quite some time. So, thanks for the suggestion and your troubles...it would have been spot on had I not first found the problem.

But one thing about the warranty issue....I had a Lincoln tech come out for a mobile service on my wife's Nautilus and I asked him a basic question about FORSCAN. The question really is immaterial, but something he said was news to me, and a lot concerning if he wasn't BS'ing me, but he said that the techs are able to see any changes made to modules for up to 60 days from when they were made....do you know if that is true? I haven't made any significant mods, just things like remotely putting down the windows with the fob, or activating Bambi mode, or Lincoln mode for the mirrors when I lock the car. I don;t think any of those could be blamed for any problem not directly impacting one of the parts modded by the change, in which case it shouldn't be cause to deny a warranty claim...unless ANY mod could be cause to deny a claim? I can't believe this might be the case as this would make pretty much any used vehicle's warranty (extended or regular) potentially worthless.

In the US, a manufacturer has to PROVE your modification caused a failure to deny a warranty.

Techs can tell if you made forscan changes becasue the as-built data in the cloud gets a modified date. That doesn't mean they are smart enough to figure out what you changed.

How many people would be interested in a quick release dock for the C4? Comma claims it's more robust and can be left on the windshield 24/7.

Yes, please.

Speed limit control. What settings do I look for. My truck gets the data but my truck is no longer responding. 2.2 ford control. Funny thing is I haven't touched a thing in 10 months

Dang I totally forgot about the Ford settings. Thanks.
The other day I posted about my truck over correcting in curves on interstate. Its late in correcting its center at the start of the curve. Gets close to the inside or outside of the lane marker and then decides to correct by aggressively moving back to center. That results in over shooting center and aggressively going back causing a out of control ping pong effect that ends up going out of control.
I had the opportunity all last week to observe as i had the same 90 mile trip each day for 10 days.
You mentioned it could be something in my suspension. My truck has 20k miles.
The temps were barley over 12deg.
I noticed that my steering was tighter than normal. Im wondering if my comma was late to make the slight corrections in the curve resulting in getting too close to the edge marker. Resulting in a more than normal torque output to get to center. So on and so on.
I haven't done anything other than a recalibration yet.
My speed was 76mph. When slowing to 65 its much much better.
But I still notice that its late in reacting . Gets closer to the side lane markers before reacting. Maybe it is but everything is in my linkage is tight and it takes more torque.

I agree with you that the software just doesn't rewrite itself.
It could be the stock sensitivity or steering rate is set for normal conditions.
I have another trip tomorrow of 100 miles. Morning temps will be 25 and afternoon temps around 40. I will test my theory unless you have an idea like changing lane centering settings. I remembered making a adjustment about 10 months ago when it was hugging the outside during a curve. It was a small change in numbers.
Centering right now in the straight is spot on. No wandering or ping pong. It just waits too long to correct.

Yesterday the temps were in the middle 30s
I had far less trouble in the curves. I suspect temperature has a bearing.
Is there a way to adjust sensitivity?
Or might it be torque?

It could be that cold hard tires make steering twitchy.

Increasing the PC Blend Ratio will reduce the steering torque. If you are only having trouble in curves, then only increase PC Blend Ratio High.

Didn't think about my tires.
Pc blend ratio is greyd out.

Question about break actuator release delta.
What does it do?

I haven't had v2 installed in a year, please send a picture of the menu.

Nothing, we just forgot to remove it.
