HI We have this 2009 model ETVQ 25.
Start up truck and no errors and hydraulic and steer works as soon as i release handbrake switch it fails with this error 42 brake pot.

The Left leg steer magnet switches on and off and i can switch off and on through the Judit software. The one below the seat does not move during power up or when pressing the brake switch. I have tried another brake magnet and a pot still same.

The strange issue was even without errors when i check with judit it shows the steer 2 unit in green and the steer 1 unit in red. So i replaced the steer 1 unit and still the same issue. I have the truck driving ok if i physically disable brake off the motor.

Really confused me this one any ideas and suggestions would be really appreciated thanks.
