I have this electric pallet truck, and on start-up shows errors 26,56,84,88.
If i put the ignition with the foot brake pressed only shows 2 errors (56,88). But when i release the brake all errors reappear.
I mention that battery indicator and direction arrows is doing initialization on start-up but after that didn't show anything, battery indicator turns off completly, and if i switch direction lever, the arrows on the display didn't react. The position of the turning wheels are shown on display (working).
And i have the hydraulics sign cuted on display...
