Input value from lift pot in control handle fault.
One (or more) out of three things.

Analog 1 and 2 correlation greater than 0.625v
Analog 1 or 2 input value less than 0.25v
Analog 1 or 2 input value is greater than 4.75v.

You can see the input value on the display if you want but you need to be fimiliar with and able to read hexadecimal. Best to back probe the wiring at the pot on the handle to confirm voltages then confirm voltage readings at the traction/hydraulic card.
