Hello, in my BT RRE160 sn6257537(2013)
first of all I have 2 errors:
-after freelift when I try to lowering forks reachtruck do it very slow and i see 4:180 and sometimes i see error 4:195 and display shows a box with a question mark ? and 2 arrows pointing up after this.
The values on the hight indicator display are lost

I see in CID diagnostic (4) pos. 7&8 inputs change when B19 is rotated.
I replace valve Q2 - the error was not lost;
I replace MCU and after this error 3:314 appeared. although the fuse 73 is closed...

maybe someone has an idea how to fix it
Thanks
