Lane keeping, steering pilot
Hi, I loaded a stage 1 tune and now my steering pilot and lane keeping no longer work.
I have no messages in the dash.
The lights come on, on the respective driver assist switches, and the dash shows that the modes are activated but they don't do anything.
I reverted the ecu back to stock and they still don't work.
My car is hardly driven, the systems were working before the tune.
The tuner tells me it's impossible it's from the tune, as they are completely separate. (I'm not blaming them, I'm just stating that was the only event that occurred before i lost the system incase it helps anyone here understand what happened. I haven't been in rain, car wash, and the sensors are clean and free of dirt)
Is there any reset I can do, to recover the systems?

Hey Mars, a couple of questions, thoughts and ideas until someone with more experience/knowledge chimes in.
What year car and which tune? Did you notice these systems not working right after the initial install attempt or over time?
Did you fully turn car off and let sit for few seconds before starting engine after install and uninstall?
Stuff I’ve tried with electrical issues in the past: 1) Check to see if any hidden codes are thrown with appropriate ODB scanner. 2) Go into the Command system to see if there are any related systems you can toggle off/on. Sometimes a gentle reminder wakes them back up. 3) Try disconnecting negative terminal on battery for 10 minutes to see if it wakes back up after reconnecting. 4) Check to see if any related fuses may have been blown.
Just my .02 to see if any of this helps or sheds light on situation. Good luck!!!

Only way to find out is flash to stock.

Update: on a second drive I noted it was only the steering pilot assist that's not working.
Blind spot works fine.
Lane keeping vibrates the steering wheel, although its very soft and light, I didn't notice cause the suspension going over the painted lines is more aggressive than the synthetic vibrations.
Which leads me to question, what turns the wheel during steering pilot? Is it an electric motor/clutch assembly behind the steering? Could it be worn out? Cause I barely feel the lane keeping vibrations.
I checked the fuses, i disconnected the battery (for 50mins, on another note, the radio presets didn't reset, so it's seems the Comand has its own battery). There's no messages on OBD... So it's a mystery.
