Hello All,

i have a L14. Most time the lifting dont work. After readout the error code it is shown

77 Synchronisation between uC1 and uC2 failed
87 Different checksum between uC1 and UC2
69 commuication error between main and safety controller

What can be happed? Is the uC1 and uC2 Error the Potentiometer in the steering for lifitig?
What can be the Communication Error? Where is the Saftey controller located? Is there a short cut in the cable?

Many thanks for your help

Andreas
