What is XCMG General Fault Code E1060?

Fault Code E1060 on XCMG excavators indicates a communication error or malfunction in the electronic control system, specifically related to CAN bus communication failure between the main controller (ECM) and other electronic modules. This diagnostic trouble code (DTC) signals that the Engine Control Module (ECM) is unable to establish or maintain proper data exchange with peripheral controllers such as the hydraulic control unit, instrument cluster, or transmission control module.

This fault is critical because modern XCMG excavators rely on continuous CAN (Controller Area Network) bus communication to coordinate engine performance, hydraulic functions, and operator interface displays. When E1060 triggers, the machine's integrated systems cannot synchronize properly, potentially leading to reduced operational capability or complete system shutdown. For used excavators, this code often points to age-related deterioration in electrical components rather than catastrophic failures.

Common Symptoms

When Code E1060 is active, operators typically experience:

• Warning lights illuminated on the instrument panel, often accompanied by communication error messages on the digital display
• Intermittent or complete loss of gauge functionality (fuel level, temperature, pressure readings showing incorrect values or freezing)
• Reduced engine power or activation of derate mode as a protective measure
• Erratic hydraulic response or unresponsive auxiliary functions due to controller miscommunication
• Difficulty starting the machine or unexpected shutdowns during operation

Potential Causes

The most common technical reasons for E1060 in used XCMG excavators include:

• Damaged or corroded CAN bus wiring harness, particularly at flex points near the cab mounting or boom pivot areas where vibration causes wire chafing
• Loose or oxidized electrical connectors at the ECM, instrument cluster, or junction boxes due to moisture intrusion over time
• Failed termination resistors in the CAN bus network (typically 120-ohm resistors at network endpoints)
• ECM or peripheral controller failure, though less common than wiring issues in used machines
• Low voltage supply from aging batteries or failing alternators causing communication dropouts
• Aftermarket component installation that disrupted proper CAN bus topology or introduced electrical noise

How to Troubleshoot and Fix Code E1060

Step 1: Visual Inspection Begin with a thorough physical examination of all wiring harnesses associated with the CAN bus system. Focus on areas where cables route through the chassis, particularly near articulation points. Look for abraded insulation, pinched wires, or connectors with visible corrosion. On used excavators, pay special attention to connector seals that may have degraded, allowing moisture penetration.

Step 2: Electrical Testing Using a digital multimeter, verify that the CAN-High and CAN-Low lines show proper resistance. With the system powered off, measure between CAN-H and CAN-L terminals at the ECM connector—you should read approximately 60 ohms (two 120-ohm termination resistors in parallel). Check for short circuits to ground on each CAN line individually; readings should show infinite resistance. Verify battery voltage is above 12.5V, as low voltage commonly causes communication faults.

Step 3: Advanced Diagnostics Connect XCMG diagnostic software (or compatible equipment like a CANbus analyzer) to monitor real-time communication traffic. Identify which specific module is failing to respond. Check termination resistors at both ends of the CAN bus network—these frequently fail in older machines. Inspect the ECM ground connections and clean all grounding points, as poor grounds cause intermittent communication issues.

Step 4: Component Replacement If testing identifies a faulty harness section, replace the entire affected segment rather than splicing repairs, which can introduce resistance. When replacing connectors, apply dielectric grease to prevent future corrosion. If a controller module is confirmed defective, ensure replacement units match the machine's software version to avoid compatibility issues.

For complex electrical diagnostics or safety-critical repairs, engage qualified heavy equipment technicians with proper training and calibrated diagnostic tools.
