Posted this on the raptor forums, but wanted to post it here as well for advice

I wanted to see if any one has any experienced this/ and or if it is worth a trip to the dealer. I have a 2019 with 6K miles. Forscan and pedal commander are my only mods. No issues at all up to this point. I was running around today and I parked for ten minutes. I used the app to start my truck, and when I got in the dash was like a Christmas tree with the following faults:

• Wrench Icon
• Collision Warning Not Available
• Traction Control On
• Hill Start Assist Not Available
• Collision Sensor Fault
• Hill Start Assist Fault
• Supplemental Restraint Fault
• Powertrain System Fault
• Hill Descent Fault
• Emergency break functionality limited

I had no throttle response. Multiple quick succession restarts, and the faults remained. I turned it off, and let it sit for 5 minutes. I restarted it and everything was fine, and has been since. I pulled my codes, which are below. Do you think this is a transient gremlin? or should I get this checked out? seems to me like there was a crazy communication error and a restart cleared it?

Just going to say the obvious... try removing the pedal commander. The only lag that thing reduces is the lag time of your foot pushing the pedal. And is most likely the cause of your faults.

I know this is an old post, but my truck is doing the same thing. What ended up being your trucks problem?
