While using Sunnypilot, multiple engine lights turn on, including lane departure and collision protection lights, these functions are deactivated, as is the comma 3 autonomic driving. I have to turn engine off and back on. Most times engine lights disappear and it takes a few ignitions before the issue recurs. This occurred before, these engine lights appeared, then another engine light appeared regarding exhaust pressure readings. I ended up taking to dealership and they had to change the PCM. The moment I reconnected the comma, these engine lights reappeared (with exception of exhaust pressure light). I hope comma not the cause of my PCM malfunction and it's bound to happen again, not to mention the risk entailed with inactivation of protection systems.
Car model is 2020 RAM 1500 Limited.
