plugging in Soler TC controller module while driving
Today, I was driving on the interstate and decided to plug in the controller for the Soler throttle controller to see what mode I was in. I usually keep it unplugged and in the center console. Anyway, as soon as I plugged it in, the car went into limp-home mode. I pulled over, shut it down, and restarted, hoping it would come out of it, but I knew better. I didn't have my code reader or a wrench to pull the battery cable, so I drove it the rest of the way home in reduced power mode, which was only 5 miles. When I got home, I hooked up my Autel and looked up the codes. It reported P0697 and P06A3, which I understand are related to input from the throttle position sensor or the pedal. I pulled the battery cable to get a fresh start, and the car drove fine after a test drive around town.
I guess it isn't a good thing to do what I did? I'm sure it was pretty funny to the people I had passed that were now seeing me on the side of the road.

Happened to me once. No irregular driving or anything like that. When I got home after driving and reduced speed, I did two things. First of all my phone charger cord, I put that out of the way of the controller. That way I don't make a mistake by plugging in the wrong Court to the controller. The controller is in the console the wires ran up under the console and it stays that way. The charger for the phone is in the cigarette lighter charger thing and it stays separate. So I was thinking that might be the reason. The second thing I did is I went up under there where the gas pedal is and I made sure the connections were nice and tight just in case I accidentally hit something and the plugin module wasn't seating correctly. After that everything was fine. I had remembered seeing a post on tiktok or Facebook where someone says that the soler throttle body connector has pin problems sometimes. I don't know if that's true or not but doing the two things I mentioned above fixed my problem.

Thanks. I thought about unplugging the TC on the side of the road and bypassing it, but I wasn't a fan of contorting myself to get down there as semis passed by, blowing dust on me.

I keep the controller plugged in all the time and haven't tried what you did with yours. Good to know that problems can occur if you plug the controller in while driving.

I had a similar issue a while back, had the dealer change the battery while in for an oil change. When I got the car back and before leaving the dealer's lot, I started checking all the stuff that could have been affected by the battery change. The display on my phone for the Soler interface looked different, so I unplugged to dongle and plugged it back in, thinking maybe it needed to be rebooted or something. The car immediately went into limp mode and through a couple of codes. I talked with the service advisor and he plugged in his fancy code reader then went back to his computer and cleared the codes, been fine ever since.
Moral of the story is if you want to unplug or plug in the dongle, make sure the ignition is OFF, open the door and let the car cycle through the power up and power down cycle so there is no power going to the dongle cable before plugging it in or unplugging it.

I'm just glad it did it as soon as I plugged it in, not later on that day or even days later. When you can correlate an action to a problem, it makes it easy. These cars do not like electrical issues at all, but we all know that. I am just glad I could maintain speed. When I had issues with a Soler throttle body putting it in limp mode, the car shook like crazy, and I thought the body panels would fall off. I couldn't go over 35. Side note, Soler fixed the throttle body problem, no charge.

I had this happen to me randomly a couple times with the older non bluetooth model. I just got under the dash, disconnected it and all was fine. I have since upgraded and don't even use the display module...
