Diagnostics of LICCON system error codes - Liebherr LTM-1070-4.1 Crane

The Liebherr LTM-1070-4.1 mobile crane is equipped with an advanced LICCON control and diagnostic system. This system continuously monitors operating parameters of hydraulic and electrical components, safety sensors (LMB), and the LSB/CAN data bus. In case of abnormalities, central computers generate detailed error codes stored in the diagnostic log.

The following catalog contains a list of LICCON system error codes for the Liebherr LTM-1070-4.1 model. The tips facilitate quick fault identification, indicate the appropriate plug connectors, and recommended repair procedures.
