I was unable to look at analyzer 2.2.x - the menu skipped from 2.1 to 2.3.

2.3.8 has pot1 = 0.25v

Looking at calibration menu 3.1 I did see c1 accel pedal. Scrolling to that brought up message - "Close seat switch".

The only 2 options showing in calibration menu is c1 accel pedal and c2 battery

It does seem the seat switch is not functioning correctly. I checked the ground attaching out of the seat to the rails because it looked corroded but had no effect.
