# Diagnostics of LICCON System Error Codes - Liebherr LTM-1070-4.1

The **LICCON (Liebherr Computed Control)** control system in the **Liebherr LTM-1070-4.1** mobile crane constantly monitors the technical condition of electronic components, LSB/CAN bus sensors, and input/output modules. If an irregularity is detected, the system generates a dedicated error code, logs it in memory, and takes appropriate safety measures (e.g., stopping crane movements).

The following catalog contains a list of LICCON system error codes for the Liebherr LTM-1070-4.1 model, including cause descriptions, system reactions, and troubleshooting guidelines.

### Service Guide: Computer Diagnostics and LSB Bus in Liebherr Cranes

Modern Liebherr LTM-1070-4.1 mobile cranes base their operation on an advanced LSB (Liebherr-System-Bus) and CAN bus network. All sensors—from pressure transducers in luffing cylinders to angle and length sensors on the telescopic boom—communicate with central units (ZE 0, ZE 1, ZE 2) in real time.

When an LSB communication error appears on the LICCON controller display (e.g., M00020004-M00022567 series errors), first inspect signal cables physically, check for mechanical sensor damage, and verify the condition of plug connectors (e.g., X635, X635A, X635B). Contamination, moisture, or a voltage drop in the sensor power supply circuit are the most common causes of data transmission interruptions.
