What is Hitachi ZX210LCK-5G Fault Code 13007-2?

Fault Code 13007-2 on the Hitachi ZX210LCK-5G excavator indicates a malfunction in the Engine Control Module (ECM) communication circuit, specifically related to CAN (Controller Area Network) bus communication errors between the engine controller and other machine systems. This code triggers when the ECM detects intermittent or complete loss of data transmission on the CAN bus network, which is the digital backbone connecting the engine, hydraulic system, and display monitor.

This fault is critical for the ZX210LCK-5G because the Isuzu engine in this model relies on continuous communication between multiple controllers to optimize fuel injection timing, hydraulic pump output, and emissions controls. When communication breaks down, the machine enters a protective derate mode to prevent potential damage, significantly reducing operational efficiency.

Common Symptoms

• Engine warning lamp illuminated on the instrument cluster with reduced engine power output
• Intermittent or complete loss of monitor display information (engine RPM, temperature gauges freezing or blinking)
• Machine entering limp mode with limited hydraulic functions and reduced swing speed
• Erratic throttle response or engine stalling during operation, particularly when switching between work modes
• Error messages appearing on the multi-function display indicating "Communication Error" or "ECM Fault"

Potential Causes

The most common technical causes for Code 13007-2 on used ZX210LCK-5G excavators include:

• CAN bus wiring harness damage from chafing against the engine block or frame rails, particularly near the battery box area where harnesses route through tight spaces
• Corroded or loose CAN-H and CAN-L wire connections at the ECM connector (common on machines with 4,000+ operating hours)
• Failed 120-ohm terminating resistors on either end of the CAN bus network causing signal reflection errors
• ECM internal failure or corrupted firmware, though less common than wiring issues
• Water intrusion into the main wiring harness connector behind the cab, a known vulnerability point on this model series

How to Troubleshoot and Fix Code 13007-2

Step 1: Visual Inspection of Harnesses Begin by inspecting all engine harness routing from the ECM (located under the right-hand side panel) to the instrument cluster. On used excavators, check for harness wear at known friction points: where cables pass through the bulkhead grommet and near the hydraulic pump mounting bracket. Look for abraded wire insulation, green corrosion on pins, or oil-soaked connectors.

Step 2: CAN Bus Electrical Testing Using a digital multimeter, disconnect the battery and measure terminating resistor values at the ECM connector. Between CAN-H (typically pin 23) and CAN-L (pin 24), you should read approximately 60 ohms with both terminating resistors intact. A reading of 120 ohms indicates one resistor has failed; infinite resistance means both are open or wiring is severed.

Step 3: Live Data Verification Reconnect power and use Hitachi Dr.EX diagnostic software or a compatible J1939 scanner to monitor real-time CAN bus activity. Check for communication dropouts while wiggling harness sections. If communication fails when manipulating specific harness areas, repair or replace that section with marine-grade heat-shrink connections.

Step 4: ECM and Connector Service Remove and clean the ECM connector with electrical contact cleaner, applying dielectric grease to prevent future corrosion. If the code persists after harness repairs, the ECM may require reflashing or replacement—verify with Hitachi that firmware is current for your machine's serial number range.

For used excavators, always replace damaged harness sections rather than attempting tape repairs, as vibration will cause repeat failures.
