Jungheinrich TFG 320s error code E 3321

Hi,

I am working on a 2015 Jungheinrich TFG 320s.
The machine sometimes malfunctions during use and gives error code E 3321.

The error information is: "sideshift position input" actual value implausible. See attached image below for more details.

Sometimes turning the forklift off and on will solve the problem. What could be causing this error?

The machine has DuoPilot controls (2 joysticks).

Thanks for your help!
