Ok, that rules out the motor speed sensor as a cause of a erronious input from a 5 volt powered sensor, but the walkaway prevention during Tow does present a puzzle. The negative 100 reading in Mapped Throttle I've seen before in controllers that were damaged by shorting the SOC socket with a voltmeter probe, but changing controllers would have fixed that... unless the short is from one or more bent pins in the SOC socket, still shorting out. Grey wire terminal contacting either power lead terminal for the SOC meter would certainly do it.
And 5V bus splice harness corrosion issues causing encoder undervolt would have been resolved by changing the harness... unless both harnesses have the exact same corrosion. The chances of that are slim. Too bad you can't access the deep error logs, that would show the sequence of events that led up to this. There is no tool to view those logs, they must be downloaded as a file dump from the controller then use Grep to extract/view the entries.
