LICCON System Error Code Diagnostics - Liebherr LTM-1070-4.1 Mobile Crane

The LICCON (Liebherr Computed Controlling) onboard computer in the Liebherr LTM-1070-4.1 mobile crane continuously monitors the operating parameters of the hydraulic system, central unit ZE 2, winches, boom luffing mechanism, and LMB overload protection systems. In the guide below, we have compiled a detailed list of error codes along with the controller's response and the recommended service troubleshooting procedure.
